Increased demands on the protein folding capacity of the endoplasmic reticulum (ER) trigger the unfolded protein response (UPR). Comprised of a tripartite signaling system, the UPR regulates translation and gene transcription to manifest pro-adaptive and, if necessary, pro-apoptotic outcomes. The three UPR pathways, initiated by activating transcription factor 6, inositol requiring enzyme 1, and protein kinase RNA-activated-like ER kinase (PERK), direct distinct downstream signaling events. However, it is becoming increasingly clear that interplay between the cascades is vital in shaping the UPR. In particular, recent discoveries have revealed that PERK-dependent signals mediate both inter- and intra-pathway regulation within the UPR, underscoring the critical role of the PERK pathway in the cellular response to ER stress. © 2013 Springer Basel.

The Warfield version of systems science supports a wide variety of application areas, and is useful to practitioners who use the work program of complexity (WPOC) tool. In this article, WPOC is applied to information technology service management (ITSM) for managing the complexity of projects. In discussing the application of WPOC to ITSM, we discuss several steps of WPOC. The discovery step of WPOC consists of a description process and a diagnosis process. During the description process, 52 risk factors are identified, which are then narrowed to 20 key risk factors. All of this is done by interviews and surveys. Root risk factors (the most basic risk factors) consist of 11 kinds of common 'mindbugs' which are selected from an interpretive structural model. This is achieved by empirical analysis of 25 kinds of mindbugs. (A lesser aim of this research is to affirm that these mindbugs developed from a Western mindset have corresponding relevance in a completely different culture: the Peoples Republic of China.) During the diagnosis process, the relationships among the root risk factors in the implementation of the ITSM project are identified. The resolution step of WPOC consists of a design process and an implementation process. During the design process, issues related to the ITSM application are compared to both e-Government operation and maintenance, and software process improvement. The ITSM knowledge support structure is also designed at this time. During the implementation process, 10 keys to the successful implementation of ITSM projects are identified. © 2013 Copyright Taylor and Francis Group, LLC. Source

When a depolarizing event occurs across a cell membrane there is a remarkable change in its electrical properties. A complete depolarization event produces a considerably rapid increase in voltage that propagates longitudinally along the axon and is accompanied by changes in axial conductance. A dynamically changing magnetic field is associated with the passage of the action potential down the axon. Over 75 years of research has gone into the quantification of this phenomenon. To date, no unified model exist that resolves transmembrane polarization in a closed-form description. Here, a simple but formative description of propagated signaling phenomena in the membrane of an axon is presented in closed-form. The focus is on using both biophysics and mathematical methods for elucidating the fundamental mechanisms governing transmembrane polarization. The results presented demonstrate how to resolve electromagnetic and thermodynamic factors that govern transmembrane potential. Computational results are supported by well-established quantitative descriptions of propagated signaling phenomena in the membrane of an axon. The findings demonstrate how intracellular conductance, the thermodynamics of magnetization, and current modulation function together in generating an action potential in a unified closed-form description. The work presented in this paper provides compelling evidence that three basic factors contribute to the propagated signaling in the membrane of an axon. It is anticipated this work will compel those in biophysics, physical biology, and in the computational neurosciences to probe deeper into the classical and quantum features of membrane magnetization and signaling. It is hoped that subsequent investigations of this sort will be advanced by the computational features of this model without having to resort to numerical methods of analysis. © 2015 AIP Publishing LLC.
