The Development of a smart metering scheme

Paper no. O-036Collaboration is a term to characterize contemporary relationship between a supplier and a consumer. In the old days, an energy meter is the interface service-counter that prompts the double-coincidence of wants between the parties. Nowadays a meter can have smartness beyond registration of consumption units by the supplier. It can carry intelligence to serve demand side management. When the electrical-load-signature technology has been efficiently developed, then a user has to accept that the barrier to load monitoring and surveillance by other parties is no longer a technical issue, but primarily an ethical issue only. On the other hand, it is anticipated that experience curves shall drag down the cost of intelligent home management system to an extent that most of the homes can equip one system to enhance installation operation efficiency and human comfort. It is perceived that when a platform can be developed to permit the intelligence of two sides to share information, then each of them may support the other as a neighboring aide. This paper discusses on philosophies and models that shall develop the concepts.postprintThe International Conference on Electrical Engineering (ICEE) 2008, Okinawa, Japan, 6-10 July 2008

Are patients' and doctors' accounts of the first specialist consultation for chronic back pain in agreement?

INTRODUCTION: The first consultation at a specialist pain clinic is potentially a pivotal event in a patient’s pain history, affecting treatment adherence and engagement with longer term self-management. What doctors communicate to patients about their chronic pain and how patients interpret doctors’ messages and explanations in pain consultations are under-investigated, particularly in specialist care. Yet, patients value personalized information about their pain problem. PATIENTS AND METHODS: Sixteen patients in their first specialist pain clinic consultation and the doctors they consulted were interviewed shortly after the consultation. Framework analysis, using patient themes, was used to identify full match, partial match, or mismatch of patient–doctor dyads’ understandings of the consultation messages. RESULTS: Patients and doctors agreed, mainly implicitly, that medical treatment aiming at pain relief was primary and little time was devoted to discussion of self-management. Clinically relevant areas of mismatch included the explanation of pain, the likelihood of medical treatments providing relief, the long-term treatment plan, and the extent to which patients were expected to be active in achieving treatment goals. DISCUSSION: Overall, there appears to be reasonable concordance between doctors and patients, and patients were generally satisfied with their first consultation with a specialist. Two topics showed substantial mismatch, the estimated likely outcome of the next planned intervention and, assuming (as doctors but not patients did) that this was unsuccessful, the long-term treatment plan. It appeared that more complex issues often generate divergence of understanding or agreement. Despite the widespread recommendations to medical practitioners to check patients’ understanding directly, it does not appear to be routine practice. CONCLUSION: It is hoped that this research encourages more detailed examination of shared and divergent experiences of pain consultations and also their influence on the subsequent course of intervention and adherence to treatment (not addressed here)

Solution structure of the dimerization domain of the eurkaryotic stalk P1/P2 complex reveals the structural organization of the eukaryotic stalk

Poster Presentation: abstract A01The lateral ribosomal stalk is responsible for the kingdom‐specific binding of translation factors and activation of GTP hydrolysis during protein synthesis. The eukaryotic stalk consists of the scaffold P0 protein which binds two copies of P1/P2 hetero‐dimers to form a P0(P1/P2)2 pentameric P‐complex. The structure of the eukaryotic stalk is currently not known. To provide a better understanding on the structural organization of eukaryotic stalk, we have determined the solution structure of the N‐terminal dimerization domain …postprin

Oxygen-Vacancy-Induced Orbital Reconstruction of Ti Ions at the Interface of LaAlO3/SrTiO3 Heterostructures: A Resonant Soft-X-Ray Scattering Study

Resonant soft-x-ray scattering measurements have been performed to investigate interface electronic structures of (LaAlO3/SrTiO3) superlattices. Resonant scattering intensities at superlattice reflections show clear evidence of degeneracy lifting in t(2g) states of interface Ti ions. Polarization dependence of intensities indicates the energy of d(xy) states is lower by similar to 1 eV than two other t(2g) states. The energy splitting is insensitive to epitaxial strain. The orbital reconstruction is induced by oxygen vacancies and confined to the interface within two unit cells, indicating charge compensation at the polar interfaces.

A simple and robust method for connecting small-molecule drugs using gene-expression signatures

Interaction of a drug or chemical with a biological system can result in a gene-expression profile or signature characteristic of the event. Using a suitably robust algorithm these signatures can potentially be used to connect molecules with similar pharmacological or toxicological properties. The Connectivity Map was a novel concept and innovative tool first introduced by Lamb et al to connect small molecules, genes, and diseases using genomic signatures [Lamb et al (2006), Science 313, 1929-1935]. However, the Connectivity Map had some limitations, particularly there was no effective safeguard against false connections if the observed connections were considered on an individual-by-individual basis. Further when several connections to the same small-molecule compound were viewed as a set, the implicit null hypothesis tested was not the most relevant one for the discovery of real connections. Here we propose a simple and robust method for constructing the reference gene-expression profiles and a new connection scoring scheme, which importantly allows the valuation of statistical significance of all the connections observed. We tested the new method with the two example gene-signatures (HDAC inhibitors and Estrogens) used by Lamb et al and also a new gene signature of immunosuppressive drugs. Our testing with this new method shows that it achieves a higher level of specificity and sensitivity than the original method. For example, our method successfully identified raloxifene and tamoxifen as having significant anti-estrogen effects, while Lamb et al's Connectivity Map failed to identify these. With these properties our new method has potential use in drug development for the recognition of pharmacological and toxicological properties in new drug candidates.Comment: 8 pages, 2 figures, and 2 tables; supplementary data supplied as a ZIP fil

Nonlinear Sigma Model for Disordered Media: Replica Trick for Non-Perturbative Results and Interactions

In these lectures, given at the NATO ASI at Windsor (2001), applications of the replicas nonlinear sigma model to disordered systems are reviewed. A particular attention is given to two sets of issues. First, obtaining non-perturbative results in the replica limit is discussed, using as examples (i) an oscillatory behaviour of the two-level correlation function and (ii) long-tail asymptotes of different mesoscopic distributions. Second, a new variant of the sigma model for interacting electrons in disordered normal and superconducting systems is presented, with demonstrating how to reduce it, under certain controlled approximations, to known ``phase-only'' actions, including that of the ``dirty bosons'' model.Comment: 25 pages, Proceedings of the NATO ASI "Field Theory of Strongly Correlated Fermions and Bosons in Low - Dimensional Disordered Systems", Windsor, August, 2001; to be published by Kluwe

Liquid-infiltrated photonic crystals - enhanced light-matter interactions for lab-on-a-chip applications

Optical techniques are finding widespread use in analytical chemistry for chemical and bio-chemical analysis. During the past decade, there has been an increasing emphasis on miniaturization of chemical analysis systems and naturally this has stimulated a large effort in integrating microfluidics and optics in lab-on-a-chip microsystems. This development is partly defining the emerging field of optofluidics. Scaling analysis and experiments have demonstrated the advantage of micro-scale devices over their macroscopic counterparts for a number of chemical applications. However, from an optical point of view, miniaturized devices suffer dramatically from the reduced optical path compared to macroscale experiments, e.g. in a cuvette. Obviously, the reduced optical path complicates the application of optical techniques in lab-on-a-chip systems. In this paper we theoretically discuss how a strongly dispersive photonic crystal environment may be used to enhance the light-matter interactions, thus potentially compensating for the reduced optical path in lab-on-a-chip systems. Combining electromagnetic perturbation theory with full-wave electromagnetic simulations we address the prospects for achieving slow-light enhancement of Beer-Lambert-Bouguer absorption, photonic band-gap based refractometry, and high-Q cavity sensing.Comment: Invited paper accepted for the "Optofluidics" special issue to appear in Microfluidics and Nanofluidics (ed.

Pathophysiology of acute experimental pancreatitis: Lessons from genetically engineered animal models and new molecular approaches

The incidence of acute pancreatitis is growing and worldwide population-based studies report a doubling or tripling since the 1970s. 25% of acute pancreatitis are severe and associated with histological changes of necrotizing pancreatitis. There is still no specific medical treatment for acute pancreatitis. The average mortality resides around 10%. In order to develop new specific medical treatment strategies for acute pancreatitis, a better understanding of the pathophysiology during the onset of acute pancreatitis is necessary. Since it is difficult to study the early acinar events in human pancreatitis, several animal models of acute pancreatitis have been developed. By this, it is hoped that clues into human pathophysiology become possible. In the last decade, while employing molecular biology techniques, a major progress has been made. The genome of the mouse was recently sequenced. Various strategies are possible to prove a causal effect of a single gene or protein, using either gain-of-function (i.e., overexpression of the protein of interest) or loss-of-function studies (i.e., genetic deletion of the gene of interest). The availability of transgenic mouse models and gene deletion studies has clearly increased our knowledge about the pathophysiology of acute pancreatitis and enables us to study and confirm in vitro findings in animal models. In addition, transgenic models with specific genetic deletion or overexpression of genes help in understanding the role of one specific protein in a cascade of inflammatory processes such as pancreatitis where different proteins interact and co-react. This review summarizes the recent progress in this field. Copyright (c) 2005 S. Karger AG, Basel
