Cytochrome b562 is a periplasmic Escherichia coli protein; previous work has shown that heme can be attached covalently in vivo as a consequence of introduction of one or two cysteines into the heme-binding pocket. A heterogeneous mixture of products was obtained, and it was not established whether the covalent bond formation was catalyzed or spontaneous. Here, we show that coexpression from pl...

The cyanobacterium Synechocystis sp. strain PCC6803 possesses three modes of inorganic carbon (Ci) uptake that are inducible under Ci stress and that dramatically enhance the efficiency of the CO(2)-concentrating mechanism (CCM). The effects of Ci limitation on the mRNA transcript abundance of these inducible uptake systems and on the physiological expression of the CCM were investigated in det...

The encorporation of a custom computing machine (CCM) into the pipeline of a su-perscalar processor has been shown to allow signiicant gains in performance for general-purpose codes 1,2,3]. This paper describes the architectural features necessary for such an in-pipeline CCM to achieve maximum potential performance gains when all mapping is done automatically by the compiler. We nd that a CCM w...

− MRI of the knee is the most frequently requested MR joint study in musculoskeletal radiology. MRI gives a comprehensive examination of the knee, providing surgeons with information they cannot obtain clinically or invasively. In this paper there is estimated the sensitivity of the articulation cartilage defects imaging using MR. There were examined two animal and two human specimen knees usin...

An ongoing trend of e-learning systems is to not only concentrate on the management of learning materials and other information, but instead to focus on learning processes. Thus a stronger focus is put on the people engaged in learning activities: the learners which shall be served by an e-learning system and the teachers who instruct and guide the learners. The Conceptual Content Management (C...

China is now entering a new era of marketing. Two dramatic changes are occurring: 1) The Internet is becoming a “virtual living place;” and 2) Corporations are transforming into service-oriented enterprises. The Creative Communications Management (CCM) theory is born from the IMC theory. It proposes a change from “communication is marketing” to “communication is management,” encouraging corpora...

Cyanobacteria are photosynthetic bacteria with a unique CO2 concentrating mechanism (CCM), enhancing carbon fixation. Understanding the CCM requires a systems level perspective of how molecular components work together to enhance CO2 fixation. We present a mathematical model of the cyanobacterial CCM, giving the parameter regime (expression levels, catalytic rates, permeability of carboxysome s...

We analyze the security of the CTR + CBC-MAC (CCM) encryption mode. This mode, proposed by Doug Whiting, Russ Housley, and Niels Ferguson, combines the CTR (“counter”) encryption mode with CBC-MAC message authentication and is based on a block cipher such as AES. We present concrete lower bounds for the security of CCM in terms of the security of the underlying block cipher. The conclusion is t...

We introduce a new model called CCM+ that rectifies the inability of previous sequencebased methods to generalize across cell-types. We permit generalization by introducing arbitrary base-pair resolution covariates. We show that the addition of base-pair resolution chromatin accessibility covariate greatly aids in the prediction of cis-regulatory marks. Additionally, we show that by using cell-...

Background: Aging is accompanied by the mitigation of sleep quality in the elderly, thereby affecting their physical and social dimensions and quality of life. However, studies have not addressed sleep problems in the elderly by means of a holistic approach, such as continuous care model (CCM). Aim: The aim of this study was to determine the effects of CC...
