Salmonella FliI is the ATPase that drives flagellar protein export. It normally exists as a complex together with the regulatory protein FliH. A fliH null mutant was slightly motile, with overproduction of FliI resulting in substantial improvement of its motility. Mutations in the cytoplasmic domains of FlhA and FlhB, which are integral membrane components of the type III flagellar export appar...

over 200 known cases in the area covered by the V.D. scheme in Edinburgh during the last seven years. The number is large because of an epidemic which occurred in an institution during August 1927 in which 16 cases were affected. Undoubtedly other cases occurred which have been treated by private practitioners. The first recorded epidemic occurred in 1877 and was reported by Suchard.1 Since the...

John C. S. Harding Department of Large Animal Clinical Sciences Western College of Veterinary Medicine University of Saskatchewan Introduction Since its discovery and characterization in western Canada in 1995, the significance and dissemination of post-weaning multisystemic wasting syndrome (PMWS) has grown and the syndrome is undoubtedly a serious issue in the global swine industry. More rece...

Modern macroscopic electromagnetism employs four differential equations containing four vector fields, a source charge density, and a source current density. Two of the four fields (i.e., Ẽ (x, t) and B̃ (x, t)) are primitive fields, while the remaining two (i.e., D̃ (x, t) and H̃ (x, t)) are induction fields. Unlike the primitive fields, the induction fields do not have microscopic existence and ...

We would like to thank our reviewers and the authors of the commentaries on our paper. Though we may have scientific differences, the criticisms raised in the commentaries will undoubtedly improve our understanding of the neural basis of decision making and provide a springboard for future experiments. In our response, we clarify why our data are incompatible with both the error likelihood and ...

One image is worth 1,000 words… Undoubtedly, images are the most widespread MM data type, second only to text data Thus, it's not surprising that most efforts related to the management of MM data have concentrated on images, in particular: Automatic extraction of features Similarity measures Indexing … In the following we will provide basic information on the basic features of images Sistemi In...

The problem of regulating cell division and cell growth is undoubtedly one of the most fundamental problems of both theory and practice of contemporary biology and medicine. Modern theories of aging suggest a close relationship of aging and the processes of growth and development, also consider the age-related decrease in cellular self-renewal of tissues due to their decreased growth potential ...

Providing a reliable technology and architecture for determining the location of real world objects and people will undoubtedly enable applications, customization, and inference not currently possible. This paper documents the creation of SpotON, a new tagging technology for three dimensional location sensing based on radio signal strength analysis. Although there are many aspects to the topic ...

FK506 undoubtedly improved the survival advantage of hepatic allotransplantation. Hepatic-intestinal and multivisceral transplantation has also become a feasible therapy for patients with combined intestinal and liver failure. With better understanding of the immunologic and metabolic aspects of allo- and xenotransplantation, further clinical attempts to transplant animal organs to humans may b...

Dielectric dispersions on the Kerr constant of two polymer-stabilized blue phase liquid crystals (BPLCs) are investigated. An extended Cole-Cole model is proposed to fit the experimental results and good agreement is obtained. As the electric field frequency increases, Kerr constant decreases and the associated dielectric heating effect gradually increases. These results will undoubtedly affect...
