This paper investigates the feasibility of maintaining a social information system to support attendees at an academic conference. The main challenge of this work was to create an infrastructure where users' social activities, such as bookmarking, tagging, and social linking could be used to enhance user navigation and maximize the users' ability to locate two important types of information in conference settings: presentations to attend and attendees to meet. We developed Conference Navigator 3, a social conference support system that integrates a conference schedule planner with a social linking service. We examined its potential and functions in the context of a medium-scale academic conference. In this paper, we present the design of the system's socially enabled features and report the results of a conference-based study. Our study demonstrates the feasibility of social information systems for supporting academic conferences. Despite the low number of potential users and the short timeframe in which conferences took place, the usage of the system was high enough to provide sufficient data for social mechanisms. The study shows that most critical social features were highly appreciated and used, and provides direction for further research.

Conducting community-partnered research conferences is a powerful yet underutilized approach to translating research into practice and improving result dissemination and intervention sustainability strategies. Nonetheless, detailed descriptions of conference features and ways to use them in empirical research are rare. We describe how community-partnered conferences may be integrated into research projects by using an example of Community Partners in Care (CPIC), a large, cluster-randomized, controlled, trial (RCT) that uses community-partnered participatory research (CPPR) principles. Our conceptual model illustrates the role community-partnered research conferences may play in three study phases and describes how different conference features may increase community engagement, build two-way capacity, and ensure equal project ownership. As the number of community-partnered studies grows, so too does the need for practical tools to support this work. Community-partnered research conferences may be effectively employed in translational research to increase two-way capacity building and promote long-term intervention success.

Riboswitches are RNA elements that control gene expression through metabolite binding. The preQ1 riboswitch exhibits the smallest known ligand-binding domain and is of interest for its economical organization and high affinity interactions with guanine-derived metabolites required to confer tRNA wobbling. Here we present the crystal structure of a preQ1 aptamer domain in complex with its precursor metabolite preQ0. The structure is highly compact with a core that features a stem capped by a well organized decaloop. The metabolite is recognized within a deep pocket via Watson-Crick pairing with C15. Additional hydrogen bonds are made to invariant bases U6 and A29. The ligand-bound state confers continuous helical stacking throughout the core fold, thus providing a platform to promote Watson-Crick base pairing between C9 of the decaloop and the first base of the ribosome-binding site, G33. The structure offers insight into the mode of ribosome-binding site sequestration by a minimal RNA fold stabilized by metabolite binding and has implications for understanding the molecular basis by which bacterial genes are regulated.

In recent years, tremendous progress has been made in the development of novel drugs targeting the basic defect in patients with cystic fibrosis (CF). This breakthrough is based on a solid foundation of knowledge on CFTR's function in health and how mutations in CFTR cause CF multi-organ disease. This knowledge has been collected and continuously expanded by an active and persistent CF research community and has paved the way for precision medicine for CF. Since 2004, the European Cystic Fibrosis Society (ECFS) has held an annual Basic Science Conference that has evolved as an international forum for interdisciplinary discussion of hot topics and unsolved questions related to CF research. This Special Issue reviews CF research topics featured at the 14th ECFS Basic Science Conference and provides an up-to-date overview of recent progress in our understanding of CFTR structure and function, disease mechanisms implicated in airway mucus plugging, inflammation and abnormal host-pathogen interactions, and advancements with enhanced cell and animal model systems and breakthrough therapies directed at mutant CFTR or alternative targets. In addition, this Special Issue also identifies a number of fundamental questions and hurdles that still have to be overcome to realize the full potential of precision medicine and develop transformative therapies for all patients with CF.

The crystal structure of Bla g 2 was solved in order to investigate the structural basis for the allergenic properties of this unusual protein. This is the first structure of an aspartic protease in which conserved glycine residues, in two canonical DTG triads, are substituted by different amino acid residues. Another unprecedented feature revealed by the structure is the single phenylalanine residue insertion on the tip of the flap, with the side-chain occupying the S1 binding pocket. This and other important amino acid substitutions in the active site region of Bla g 2 modify the interactions in the vicinity ofmore » the catalytic aspartate residues, increasing the distance between them to {approx}4 {angstrom} and establishing unique direct contacts between the flap and the catalytic residues. We attribute the absence of substantial catalytic activity in Bla g 2 to these unusual features of the active site. Five disulfide bridges and a Zn-binding site confer stability to the protein, which may contribute to sensitization at lower levels of exposure than other allergens.« less

PREFACE: International Conference on Dynamics of Systems on the Nanoscale (DySoN 2012)

NASA Astrophysics Data System (ADS)

Solov'yov, Andrey V.

2013-06-01

Conference logo The Second International Conference 'Dynamics of Systems on the Nanoscale' (DySoN 2012) took place in Saint Petersburg, Russia between 30 September and 4 October 2012. The venue was the Courtyard by Marriott St Petersburg Vasilievsky Hotel, 2nd line of Vasilievsky Island 61/30A, 199178. The conference was organized by the Frankfurt Institute for Advanced Studies - Goethe University, A F Ioffe Physical-Technical Institute and Saint Petersburg State Polytechnic University. This DySoN conference has been built upon a series of International Symposia 'Atomic Cluster Collisions: structure and dynamics from the nuclear to the biological scale' (ISACC 2003, ISACC 2007, ISACC 2008, ISACC 2009 and ISACC 2011). During these meetings it has become clear that there is a need for an interdisciplinary conference covering a broader range of topics than just atomic cluster collisions, related to the Dynamics of Systems on a Nanoscale. Therefore, in 2010 it was decided to launch a new conference series under the title 'Dynamics of Systems on the Nanoscale'. The first DySoN conference took place at the National Research Council, Rome, Italy in 2010. The DySoN 2012 is the second conference in this series. The DySoN 2012 Conference promoted the growth and exchange of interdisciplinary scientific information on the structure, formation and dynamics of animate and inanimate matter on the nanometer scale. There are many examples of complex many-body systems of micro- and nanometer scale size exhibiting unique features, properties and functions. These systems may have very different nature and origin, e.g. atomic and molecular clusters, nanoobjects, ensembles of nanoparticles, nanostructures, biomolecules, biomolecular and mesoscopic systems. A detailed understanding of the structure and dynamics of these systems on the nanometer scale is an important fundamental task, the solution of which is necessary in numerous applications of nano- and biotechnology, material science and medicine. Although mesoscopic, nano- and biomolecular systems differ in their nature and origin, a number of fundamental problems are common to all of them: what are the underlying principles of self-organization and self-assembly of matter on the micro- and nanoscale? Are these principles classical or quantum? How does function emerge on the nano- and the mesoscale in systems of different origin? What criteria govern the stability of these systems? How do their properties change as a function of size and composition? How are their properties altered by their environment? Seeking answers to these questions is at the core of a new interdisciplinary field that lies at the intersection of physics, chemistry and biology, a field called Meso-Bio-Nano (MBN) Science. Both experimental and theoretical aspects of the mentioned problems were discussed at the DySoN 2012 Conference. Particular attention was devoted to dynamical phenomena and many-body effects taking place in various MBN systems, which include problems of structure formation, fusion and fission, collision and fragmentation, collective electron excitations, reactivity, nanoscale phase transitions, nanoscale insights into biodamage, channeling phenomena and many more. This volume is a collection of the contributions received from the participants of the DySoN 2012 Conference. It provides an overview of the topics, new results and ideas that have been discussed at the conference. I would like to thank all the authors of these proceedings, as well as all the participants of the conference for making it so successful. The third DySoN Conference will be held in Edinburgh in May 2014.

Stable, biocompatible, multifunctional and multicompartment nanocarriers are much needed in the field of nanomedicine. Here, we report a simple, novel strategy to design an engineered nanocarrier system featuring an oil-core/hybrid polymer/silica-shell. Silica shells with a tunable thickness were grown in situ, directly around a highly mono-disperse and stable oil-in-water emulsion system, stabilized by a double bio-functional polyelectrolyte heparin/chitosan layer. Such silica showed a complete degradation in a physiological medium (SBF) in a time frame of three days. Moreover, the outer silica shell was coated with polyethyleneglycol (PEG) in order to confer antifouling properties to the final nanocapsule. The outer silica layer combined its properties (it is an optimal bio-interface for bio-conjugations and for the embedding of hydrophilic drugs in the porous structure) with the capability to stabilize the oil core for the confinement of high payloads of lipophilic tracers (e.g. CdSe quantum dots, Nile Red) and drugs. In addition, polymer layers - besides conferring stability to the emulsion while building the silica shell - can be independently exploited if suitably functionalized, as demonstrated by conjugating chitosan with fluorescein isothiocyanate. Such numerous features in a single nanocarrier system make it very intriguing as a multifunctional platform for smart diagnosis and therapy.Stable, biocompatible, multifunctional and multicompartment nanocarriers are much needed in the field of nanomedicine.

2010-04-01

Aperiodic Logo Aperiodic'09, the sixth International Conference on Aperiodic Crystals, took place in Liverpool 13-18 September 2009. It was the first major conference in this interdisciplinary research field held in the UK. The conference, which was organised under the auspices of the Commission on Aperiodic Crystals of the International Union of Crystallography (IUCr), followed on from Aperiodic'94 (Les Diablerets, Switzerland), Aperiodic'97 (Alpe d'Huez, France), Aperiodic'2000 (Nijmegen, The Netherlands), Aperiodic'03 (Belo Horizonte, Brazil) and Aperiodic'06 (Zao, Japan). The next conference in the series will take place in Australia in 2012. The Aperiodic conference series is itself the successor to a series of Conferences on Modulated Structures, Polytypes and Quasicrystals (MOSPOQ), which were held in Marseilles (France) in 1984, Wroclaw (Poland) in 1986, Varanasi (India) in 1988 and Balatonszeplak (Hungary) in 1991. The remit of the conference covers two broad areas of research on aperiodic crystals, incommensurately modulated and composite crystals on the one hand, and quasicrystals on the other hand, sharing the property that they are aperiodically ordered solids. In addition, the conference also featured recent research on complex metal alloys, which are in fact periodically ordered solids. However, the term complex refers to their large unit cells, which may contain thousands of atoms, and as a consequence complex metal alloys share some of the properties of quasicrystalline solids. Aperiodic'09 attracted about 110 participants from across the world, including 20 UK-based scientists (the second largest group after Japan who sent 21 delegates). A particular feature of the conference series is its interdisciplinary character, and once again the range of disciplines of participants included mathematics, physics, crystallography and materials science. The programme started with three tutorial lectures on Sunday afternoon, presenting introductory overviews on quasicrystals (Eiji Abe), complex metal alloys (Alessandra Beni) and incommensurately modulated structures (Gervais Chapuis). While these were mainly aimed at younger researchers in the field, the lectures were very well attended and appreciated by the participants. The main programme ran from Monday morning until Friday lunchtime. It comprised 13 invited and 40 contributed plenary talks, and more than 40 posters, which were presented at two afternoon/evening poster sessions. The topics covered in the programme range from mathematical foundations, mathematical models, new materials, sample preparation, structure determination, physical properties and surface properties to industrial applications. Every presenter was invited to submit an article for this proceedings volume, and the 36 peer-reviewed papers in this volume present a cross-section of the range of presentations at the conference. They have been arranged into four categories, (i) quasicrystals, (ii) modulated structures, (iii) mathematical and theoretical aspects of aperiodic order, and (iv) approximants and complex phases. Prizes for best student presentations were awarded to Heinrich Orsini-Rosenberg (ETH Zurich) for his poster Tailor-made sevenfold approximants: ab-initio investigations on formation and stability and to Holger Euchner (Universität Stuttgart) for his contributed talk on Lattice dynamics in complex metallic alloys - vibrational properties of Zn11Mg2. In addition to a cash prize, Heinrich Orsini-Rosenberg received an icosahedral teapot, which was manufactured and donated by David Warrington, and Holger Euchner received a book prize. The meeting started with a welcome reception in the University's recently refurbished Victoria Gallery and Museum. A public lecture Simple sets of shapes that tile the plane but cannot ever repeat by Professor Sir Roger Penrose FRS attracted a wide audience and gave a fascinating insight into the discovery of the Penrose tiling, which is still the paradigm of aperiodic order in two dimensions and used in modelling quasicrystalline materials, some ten years before quasicrystals were first seen in experiment. The conference excursion and dinner centred on the historic waterfront area of this 800-year old city that was designated European Capital of Culture in 2008. The enjoyment of the ferry trip on the Mersey and subsequent walk to the Albert dock museums was greatly enhanced by the fine weather, which lasted throughout the entire conference week. The guests of honour at the conference dinner were Professor Sir Roger Penrose FRS and Professor Alan L Mackay FRS, bringing together two distinguished UK scientists who made seminal contributions to the subject. Besides the scientific programme, the conference also offered a presentation by the author Ann Lingard, whose latest novel The Embalmer's Book of Recipes features a mathematician working on quasicrystals at the University of Liverpool as its main character. A related EPSRC-supported workshop on Mathematical Aspects of Aperiodic Order, organised by Alex Clark, John Hunton and Uwe Grimm, was held in Leicester in the week preceding the conference, and attracted about 40 participants. It is not possible to organise a conference without the help and support of a large number of people, and we would like to take this opportunity to acknowledge the support of everyone who was involved in organising and running this conference. We would like to thank the IUCr Aperiodic Commission, and in particular its chair Professor Marc de Boissieu, who not only entrusted us with hosting the event, but acted as the International Advisory Committee and provided valuable advice and guidance. We are indebted to the members of the International Programme Committee, who helped to put together an exciting programme by suggesting invited speakers and selecting presentations for contributed plenary talks. We are immensely grateful to all members of the National Organising Committee, who provided essential support during the organising stage and during the conference itself, and we would particularly like to thank the conference secretary, Mrs Angie Reid, for her excellent administrative support before, during and after the conference, and for her help in the production of this volume. We are very much indebted to out co-editors, Dr Olga Degtyareva (Edinburgh) and Dr Hem Raj Sharma (Liverpool), for their contributions to the editing of this volume. Finally, and most of all, we would like to thank all participants of the conference for coming to Liverpool, for contributing by presenting their recent work and taking part in discussions, and for creating such an enjoyable and fruitful collegiate atmosphere throughout the week. Last but not least we would like to express our gratitude for the generous financial support we received from the Open University, the University of Liverpool and the Institute of Physics (Mathematical and Theoretical Physics Group and Thin Films and Surfaces Group). The International Union of Crystallography provided financial sponsorship which was allocated to support the participation of 15 young scientists. The European Network of Excellence on Complex Metallic Alloys provided travel and subsistence support to members of participating organisations. Rónán McGrath Uwe Grimm Conference photograph

Morphological optimization for access to dual oxidants in biofilms

A major theme driving research in biology is the relationship between form and function. In particular, a longstanding goal has been to understand how the evolution of multicellularity conferred fitness advantages. Here we show that biofilms of the bacterium Pseudomonas aeruginosa produce structures that maximize cellular reproduction. Specifically, we develop a mathematical model of resource availability and metabolic response within colony features. This analysis accurately predicts the measured distribution of two types of electron acceptors: oxygen, which is available from the atmosphere, and phenazines, redox-active antibiotics produced by the bacterium. Using this model, we demonstrate that the geometry of colony structures is optimal with respect to growth efficiency. Because our model is based on resource dynamics, we also can anticipate shifts in feature geometry based on changes to the availability of electron acceptors, including variations in the external availability of oxygen and genetic manipulation that renders the cells incapable of phenazine production.

Three marine macroalgae, i.e., Grateloupia filicina, Ulva pertusa and Sargassum qingdaoense, were selected as the deputies of Rhodophyta, Chlorophyta and Ochrophyta for comparative analysis of the molecular structures and biological activities of sulfated polysaccharides (SP). The ratio of water-soluble polysaccharides, the monosaccharide composition and the sulfated contents of three extracted SPs were determined, and their structures were characterized by Fourier transformation infrared spectroscopy. In addition, biological activity analysis showed that all three SPs had immune-modulatory activity both in vitro and in vivo, and SPs from S. qingdaoense had the best effect. Further bioassays showed that three SPs could not only enhance the immunity level stimulated by inactivated avian influenza virus (AIV) in vivo but also significantly inhibited the activity of activated AIV (H9N2 subtype) in vitro. G. filicina SP exhibited the strongest anti-AIV activity. These results revealed the variations in structural features and bioactivities among three SPs and indicated the potential adjuvants for immune-enhancement and anti-AIV. PMID:26729137

The fifth annual meeting of the ASME/AIAA Smart Materials, Adaptive Structures and Intelligent Systems Conference (SMASIS) was held in beautiful Stone Mountain near Atlanta, GA. It is the conference's objective to provide an up-to-date overview of research trends in the entire field of smart materials systems. This was reflected in keynote speeches by Professor Eduard Arzt (Institute of New Materials and Saarland University, Saarbrücken, Germany) on 'Micro-patterned artificial 'Gecko' surfaces: a path to switchable adhesive function', by Professor Ray H Baughman (The Alan G MacDiarmid NanoTech Institute, University of Texas at Dallas) on 'The diverse and growing family of carbon nanotube and related artificial muscles', and by Professor Richard James (University of Minnesota) on 'The direct conversion of heat to electricity using multiferroic materials with phase transformations'. SMASIS 2012 was divided into eight symposia which span basic research, applied technological design and development, and industrial and governmental integrated system and application demonstrations. • SYMP 1. Development and characterization of multifunctional materials. • SYMP 2. Mechanics and behavior of active materials. • SYMP 3. Modeling, simulation and control of adaptive systems. • SYMP 4. Integrated system design and implementation. • SYMP 5. Structural health monitoring/NDE. • SYMP 6. Bio-inspired materials and systems. • SYMP 7. Energy harvesting. • SYMP 8. Structural and materials logic. This year we were particularly excited to introduce a new symposium on energy harvesting, which has quickly matured from a special track in previous years to an independent symposium for the first time. The subject cuts across fields by studying different materials, ranging from piezoelectrics to electroactive polymers, as well as by emphasizing different energy sources from wind to waves and ambient vibrations. Modeling, experimental studies, and technology applications all belong to the symposium topics. In addition, the conference also featured a special symposium dedicated to DARPA's structural and materials/logic program. The program seeks to enable structural systems to adapt to varying loads and simultaneously exhibit both high stiffness and high damping. Authors of selected papers in the materials areas (symposia 1, 2, and 6) as well as energy harvesting (symposium 7) were invited to write a full journal article on their presentation topic for publication in this special issue of Smart Materials and Structures . This collection of papers demonstrates the exceptional quality and originality of the conference presentations. We are very appreciative of their efforts to produce this collection of highly relevant articles on smart materials.

We have recently identified a new class of compounds that selectively kill cells that express P-glycoprotein (P-gp, MDR1), the ATPase efflux pump that confers multidrug resistance on cancer cells. Several isatin-β-thiosemicarbazones from our initial study have been validated, and a range of analogs synthesized and tested. A number demonstrated improved MDR1-selective activity over the lead, NSC73306 (1). Pharmacophores for cytotoxicity and MDR1-selectivity were generated to delineate the structural features required for activity. The MDR1-selective pharmacophore highlights the importance of aromatic/hydrophobic features at the N4 position of the thiosemicarbazone, and the reliance on the isatin moiety as key bioisosteric contributors. Additionally, a quantitative structure-activity relationship (QSAR) model that yielded a cross-validated correlation coefficient of 0.85 effectively predicts the cytotoxicty of untested thiosemicarbazones. Together, the models serve as effective approaches for predicting structures with MDR1-selective activity, and aid in directing the search for the mechanism of action of 1. PMID:19397322

Iridescent colours have been fascinating to humans throughout history; they are flashy, shimmering, dynamic, and examples surround us, from the commonly seen iridescent sheen of oily street puddles to the exotic, gaudy displays of birds-of-paradise featured in nature documentaries. Iridescent colours and the structures that produce them have unique properties in comparison with other types of colourants found in nature. Scientists from a variety of disciplines study the optics, development, heritability, chemical make-up, origin, evolution, functions and biomimetic technological applications of naturally occurring iridescent colours. For the first time, graduate students at Arizona State University brought together these scientists, along with educators and artists, at 'Iridescence: more than meets the eye', a conference to promote interdisciplinary communication and collaboration in the study of iridescent coloration from all of these perspectives. Here, we summarize the outcomes of this conference, introduce the papers that follow in this special journal issue and briefly review the current status of our understanding of iridescence.

The beginning of Francoist psychiatry: the National Neurology and Psychiatry Conference (Barcelona, 1942).

PubMed

Huertas, Rafael

While there has been some research into Francoist psychiatry, much work still needs to be done on the reorganization of the mental health profession within the new state. Held in Barcelona on 12, 13 and 14th January 1942, the National Neurology and Psychiatry Conference undoubtedly played a major role in the attempt to overthrow the dominant ideas in the field of Spanish psychiatry and displace its most influential figures. This article seeks to analyse the Conference's main organizational features and examine its most significant content, with the aim of evaluating its strategic importance in the context of both the psychiatrists' professional and scientific interests and their ideological and political concerns. Conference papers tackled issues such as neurology and psychiatry in wartime, vitamin deficiency and the nervous system, and new psychiatric treatments, including shock therapy. The Conference's marked ideological nature represented the beginning of a new professional dynamic, featuring the emergence or establishment of new leaders intent on laying the foundations of psychiatry during the early years of the Franco regime.

Photosynthesis is the biological process that converts solar energy into chemical energy. Elucidation of the mechanisms of photosynthetic energy conversion at a molecular level is fundamentally important for understanding the biology of photosynthetic organisms, for optimizing biological solar fuels production, and for developing biologically inspired approaches to solar energy conversion. The 2011 Gordon Conference on Photosynthesis will present cutting-edge research focusing on the biochemical aspects of photosynthesis, including: (1) structure, assembly, and function of photosynthetic complexes; (2) the mechanism of water splitting by PSII; (3) light harvesting and quenching; (4) alternative electron transport pathways; (5) biosynthesis of pigments and cofactors;more » and (6) improvement of photosynthesis for bioenergy and food production. Reflecting the interdisciplinary nature of photosynthesis research, a diverse group of invited speakers will represent a variety of scientific approaches to investigate photosynthesis, such as biochemistry, molecular genetics, structural biology, systems biology, and spectroscopy. Highly interactive poster sessions provide opportunities for graduate students and postdocs to present their work and exchange ideas with leaders in the field. One of the highlights of the Conference is a session featuring short talks by junior investigators selected from the poster presentations. The collegial atmosphere of the Photosynthesis GRC, with programmed discussion sessions as well as informal gatherings in the afternoons and evenings, enables participants to brainstorm, exchange ideas, and forge new collaborations. For the second time, this Conference will be immediately preceded by a Gordon Research Seminar on Photosynthesis (June 11-12, 2011, at the same location), with a focus on 'Photosynthesis, Bioenergy, and the Environment.' The GRS provides an additional opportunity for graduate students and postdocs to present their research, and it provides a mechanism to encourage active participation by junior scientists interested in photosynthesis and its applications.« less

Augmentation of symptom severity is the main complication of dopaminergic treatment of restless legs syndrome (RLS). The current article reports on the considerations of augmentation that were made during a European Restless Legs Syndrome Study Group (EURLSSG)-sponsored Consensus Conference in April 2006 at the Max Planck Institute (MPI) in Munich, Germany, the conclusions of which were endorsed by the International RLS Study Group (IRLSSG) and the World Association of Sleep Medicine (WASM). The Consensus Conference sought to develop a better understanding of augmentation and generate a better operational definition for its clinical identification. Current concepts of the pathophysiology, clinical features, and therapy of RLS augmentation were evaluated by subgroups who presented a summary of their findings for general consideration and discussion. Recent data indicating sensitivity and specificity of augmentation features for identification of augmentation were also evaluated. The diagnostic criteria of augmentation developed at the National Institutes of Health (NIH) conference in 2002 were reviewed in light of current data and theoretical understanding of augmentation. The diagnostic value and criteria for each of the accepted features of augmentation were considered by the group. A consensus was then developed for a revised statement of the diagnostic criteria for augmentation. Five major diagnostic features of augmentation were identified: usual time of RLS symptom onset each day, number of body parts with RLS symptoms, latency to symptoms at rest, severity of the symptoms when they occur, and effects of dopaminergic medication on symptoms. The quantitative data available relating the time of RLS onset and the presence of other features indicated optimal augmentation criteria of either a 4-h advance in usual starting time for RLS symptoms or a combination of the occurrence of other features. A paradoxical response to changes in medication dose also indicates augmentation. Clinical significance of augmentation is defined. The Consensus Conference agreed upon new operational criteria for the clinical diagnosis of RLS augmentation: the MPI diagnostic criteria for augmentation. Areas needing further consideration for validating these criteria and for understanding the underlying biology of RLS augmentation are indicated.

A quark model analysis of the transversity distribution

NASA Astrophysics Data System (ADS)

Scopetta, Sergio; Vento, Vicente

1998-04-01

The feasibility of measuring chiral-odd parton distribution functions in polarized Drell-Yan and semi-inclusive experiments has renewed theoretical interest in their study. Models of hadron structure have proven successful in describing the gross features of the chiral-even structure functions. Similar expectations motivated our study of the transversity parton distributions in the Isgur-Karl and MIT bag models. We confirm, by performing a NLO calculation, the diverse low x behaviors of the transversity and spin structure functions at the experimental scale and show that it is fundamentally a consequence of the different behaviors under evolution of these functions. The inequalities of Soffer establish constraints between data and model calculations of the chiral-odd transversity function. The approximate compatibility of our model calculations with these constraints confers credibility to our estimates.

A distance constrained synaptic plasticity model of C. elegans neuronal network

NASA Astrophysics Data System (ADS)

Badhwar, Rahul; Bagler, Ganesh

2017-03-01

Brain research has been driven by enquiry for principles of brain structure organization and its control mechanisms. The neuronal wiring map of C. elegans, the only complete connectome available till date, presents an incredible opportunity to learn basic governing principles that drive structure and function of its neuronal architecture. Despite its apparently simple nervous system, C. elegans is known to possess complex functions. The nervous system forms an important underlying framework which specifies phenotypic features associated to sensation, movement, conditioning and memory. In this study, with the help of graph theoretical models, we investigated the C. elegans neuronal network to identify network features that are critical for its control. The 'driver neurons' are associated with important biological functions such as reproduction, signalling processes and anatomical structural development. We created 1D and 2D network models of C. elegans neuronal system to probe the role of features that confer controllability and small world nature. The simple 1D ring model is critically poised for the number of feed forward motifs, neuronal clustering and characteristic path-length in response to synaptic rewiring, indicating optimal rewiring. Using empirically observed distance constraint in the neuronal network as a guiding principle, we created a distance constrained synaptic plasticity model that simultaneously explains small world nature, saturation of feed forward motifs as well as observed number of driver neurons. The distance constrained model suggests optimum long distance synaptic connections as a key feature specifying control of the network.

The replication of enterovirus 71 (EV71) and coxsackievirus A16 (CVA16), which are the major cause of hand, foot and mouth disease (HFMD) in children, can be inhibited by the capsid binder GPP3. Here, we present the crystal structure of CVA16 in complex with GPP3, which clarifies the role of the key residues involved in interactions with the inhibitor. Based on this model, in silico docking was performed to investigate the interactions with the two next-generation capsid binders NLD and ALD, which we show to be potent inhibitors of a panel of enteroviruses with potentially interesting pharmacological properties. A meta-analysis was performed using the available structural information to obtain a deeper insight into those structural features required for capsid binders to interact effectively and also those that confer broad-spectrum anti-enterovirus activity.

The aim of the review was to obtain information on specific activities undertaken by professional nursing organizations, in order to promote and develop Evidence-Based Nursing (EBN). The foreign organizations featured in the study actively promote EBN within their countries of origin. This activity is currently focused on the structural and financial measures (focused on extrinsic factors). Some organizations are lobbying governments for grants and general support, in order to further their use and development of EBN. Educational activities are still ongoing, which include the creation of the creation of new guidelines and publishing research in journals, along with the organization of periodic conferences. Polish Nurses Association was the only one not involved in any structural and financial activities.

Architecture of conference control functions

Kausar, Nadia; Crowcroft, Jon

1999-11-01

Conference control is an integral part in many-to-many communications that is used to manage and co-ordinate multiple users in conferences. There are different types of conferences which require different types of control. Some of the features of conference control may be user invoked while others are for internal management of a conference. In recent years, ITU (International Telecommunication Union) and IETF (Internet Engineering Task Force) have standardized two main models of conferencing, each system providing a set of conference control functionalities that are not easily provided in the other one. This paper analyzes the main activities appropriate for different types of conferences and presents an architecture for conference control called GCCP (Generic Conference Control Protocol). GCCP interworks different types of conferencing and provides a set of conference control functions that can be invoked by users directly. As an example of interworking, interoperation of IETF's SIP and ITU's H.323 call control functions have been examined here. This paper shows that a careful analysis of a conferencing architecture can provide a set of control functions essential for any group communication model that can be extensible if needed.

Identification of upstream and intragenic regulatory elements that confer cell-type-restricted and differentiation-specific expression on the muscle creatine kinase gene

DOE Office of Scientific and Technical Information (OSTI.GOV)

Sternberg, E.A.; Spizz, G.; Perry, W.M.

1988-07-01

Terminal differentiation of skeletal myobalsts is accompanied by induction of a series of tissue-specific gene products, which includes the muscle isoenzymte of creatine kinase (MCK). To begin to define the sequences and signals involved in MCK regulation in developing muscle cells, the mouse MCK gene has been isolated. Sequence analysis of 4,147 bases of DNA surrounding the transcription initiation site revealed several interesting structural features, some of which are common to other muscle-specific genes and to cellular and viral enhancers.

Ancestral multipartite units in light-responsive plant promoters have structural features correlating with specific phototransduction pathways.

PubMed Central

Argüello-Astorga, G R; Herrera-Estrella, L R

1996-01-01

Regulation of plant gene transcription by light is mediated by multipartite cis-regulatory units. Previous attempts to identify structural features that are common to all light-responsive elements (LREs) have been unsuccessful. To address the question of what is needed to confer photoresponsiveness to a promoter, the upstream sequences from more than 110 light-regulated plant genes were analyzed by a new, phylogenetic-structural method. As a result, 30 distinct conserved DNA module arrays (CMAs) associated with light-responsive promoter regions were identified. Several of these CMAs have remained invariant throughout the evolutionary radiation of angiosperms and are conserved between homologous genes as well as between members of different gene families. The identified CMAs share a gene superfamily-specific core that correlates with the particular phytochrome-dependent transduction pathway that controls their expression, i.e. ACCTA(A/C)C(A/C) for the cGMP-dependent phenylpropanoid metabolism-associated genes, and GATA(A/T)GR for the Ca2+/calmodulin-dependent photosynthesis-associated nuclear genes. In addition to suggesting a general model for the functional and structural organization of LREs, the data obtained in this study indicate that angiosperm LREs probably evolved from complex cis-acting elements involved in regulatory processes other than photoregulation in gymnosperms.

Structural Basis for the Species-Selective Binding of N,C-Capped Dipeptides to the Mycobacterium tuberculosis Proteasome

DOE Office of Scientific and Technical Information (OSTI.GOV)

Hsu, Hao-Chi; Singh, Pradeep K.; Fan, Hao

The Mycobacterium tuberculosis (Mtb) 20S proteasome is vital for the pathogen to survive under nitrosative stress in vitro and to persist in mice. To qualify for drug development, inhibitors targeting Mtb 20S must spare both the human constitutive proteasome (c-20S) and immunoproteasome (i-20S). We recently reported members of a family of noncovalently binding dipeptide proteasome inhibitors that are highly potent and selective for Mtb 20S over human c-20S and i-20S. To understand the structural basis of their potency and selectivity, we have studied the structure–activity relationship of six derivatives and solved their cocrystal structures with Mtb 20S. The dipeptide inhibitorsmore » form an antiparallel β-strand with the active site β-strands. Selectivity is conferred by several features of Mtb 20S relative to its mouse counterparts, including a larger S1 pocket, additional hydrogen bonds in the S3 pocket, and hydrophobic interactions in the S4 pocket. Serine-20 and glutamine-22 of Mtb 20S interact with the dipeptides and confer Mtb-specific inhibition over c-20S and i-20S. The Mtb 20S and mammalian i-20S have a serine-27 that interacts strongly with the dipeptides, potentially explaining the higher inhibitory activity of the dipeptides toward i-20S over c-20S. This detailed structural knowledge will aid in optimizing the dipeptides as anti-tuberculosis drugs.« less

There were also 6 community-organized workshops featuring 30more » additional talks on topics including Frontiers in Plant Systems Biology, Sources and strategies for Gene Structure, Gene Function, and Metabolic Pathway annotation at TAIR and AraCyc, Advanced Bioinformatic Resources for Arabidopsis, Laser Microtechniques and Applications with Arabidopsis, Plant Proteomics- Tools, Approaches, Standards and Breakthroughs in Studying the Proteome, and Phytohormone Biosynthesis and Signal Transduction. Conference organizers arranged a special seminar by Jim Collins (head of the Directorate of Biosciences at NSF) to provide a community discussion forum regarding the future of Arabidopsis research. Approximately 575 posters were presented in topic areas including, among others, Development, Signal Transduction, Cell Walls, Non-Arabidopsis Systems, and Interactions with Biotic and Abiotic Factors. All conference abstracts and the full program are posted at The Arabidopsis Information Resource (TAIR), a publicly-accessibly website (www.arabidopsis.org/news/abstracts.jsp.) A survey completed by approximately 40% of the meeting attendees showed high satisfaction with the quality of the presentations, meeting organization and the city of Montreal. The conference is the largest annual international Arabidopsis venue which allowed the exchange of information at the forefront of Arabidopsis research and facilitated the establishment of new, and the strengthening of old, collaborations and networks. In addition, the conference provides the site for the annual meetings of the Multinational Arabidopsis Steering Committee (MASC) and the North American Arabidopsis Steering Committee (NAASC.) Graduate students, postdoctoral researchers, junior faculty, and underrepresented minorities made up half of the oral presentations thereby promoting the training of young scientists and facilitating important career development opportunities for speakers. Several poster sessions provided an opportunity for younger participants to freely meet with more established scientists. The NAASC continued its outreach efforts and again sponsored two special luncheons to encourage personal and professional development of young scientists and underrepresented minorities. The Emerging Scientists Luncheon featured 8 graduate students selected on the basis of scientific excellence of their submitted research abstracts. Also attending were the Keynote Speaker and faculty conference organizers. The Minority Funding Luncheon, featured 7 awardees (2 female graduate students, 2 female faculty, 2 male graduate students and 1 male faculty) selected by the NAASC through a widely-publicized application process. This luncheon was established specifically to provide an opportunity for underrepresented minorities, and/or scientists from Minority-Serving Institutions/Historically Black Colleges and Universities to network with NAASC members and representatives from federal funding agencies in an informal and intimate setting. This luncheon included introductions of each award recipient and discussion of outreach efforts and informal research and career discussions. Staff members from The Arabidopsis Information Resource (TAIR), the public U.S. Arabidopsis bioinformatics resource, led one workshop and participated in another to convey information to the community about Arabidopsis resources. Participation by young researchers was facilitated through DOE-sponsored registration awards to 10 early career applicants from the US including five graduate students, four postdoctoral scholars and one new assistant faculty member.« less

Iridescence: views from many angles

Iridescent colours have been fascinating to humans throughout history; they are flashy, shimmering, dynamic, and examples surround us, from the commonly seen iridescent sheen of oily street puddles to the exotic, gaudy displays of birds-of-paradise featured in nature documentaries. Iridescent colours and the structures that produce them have unique properties in comparison with other types of colourants found in nature. Scientists from a variety of disciplines study the optics, development, heritability, chemical make-up, origin, evolution, functions and biomimetic technological applications of naturally occurring iridescent colours. For the first time, graduate students at Arizona State University brought together these scientists, along with educators and artists, at ‘Iridescence: more than meets the eye’, a conference to promote interdisciplinary communication and collaboration in the study of iridescent coloration from all of these perspectives. Here, we summarize the outcomes of this conference, introduce the papers that follow in this special journal issue and briefly review the current status of our understanding of iridescence.

A critical stage in malaria transmission occurs in the Anopheles mosquito midgut, when the malaria parasite, Plasmodium, ingested with blood, first makes contact with the gut epithelial surface. To understand the response mechanisms within the midgut environment, including those influenced by resident microbiota against Plasmodium, we focus on a midgut bacteria species' intra-specific variation that confers diversity to the mosquito's competency for malaria transmission. Serratia marcescens isolated from either laboratory-reared mosquitoes or wild populations in Burkina Faso shows great phenotypic variation in its cellular and structural features. Importantly, this variation is directly correlated with its ability to inhibit Plasmodium development within the mosquito midgut. Furthermore, this anti-Plasmodium function conferred by Serratia marcescens requires increased expression of the flagellum biosynthetic pathway that is modulated by the motility master regulatory operon, flhDC. These findings point to new strategies for controlling malaria through genetic manipulation of midgut bacteria within the mosquito. PMID:23571408

Intakes conference: understanding the impact of resident autonomy on a morning report conference.

PubMed

Moreno, Megan A; Shaffer, David Williamson

2006-01-01

Morning report (MR) is one of the most common conferences in medical residency training. Literature has suggested that an imposed structure is necessary for success. However, studies have suggested that rigid structure may decrease resident motivation. Three goals of a successful MR include large breadth of presented cases, high resident participation, and well-formatted presentations. In this article, we present a qualitative case analysis of an unstructured resident- led MR and analyze breadth of cases, resident participation, and presentation format. We collected data that included case presentation tracking, video recording conferences, and interviewing residents and faculty. Case presentations covered a broad range of topics with little duplication (2.2%). Residents preformed most (94%) of presentations; most residents (92.3%) presented cases. Case presentations were structured in 1 of 3 formats that fulfilled suggested guidelines from MR literature. In this unstructured MR conference, structural aims were met with the relatively autonomous decisions of motivated resident participants.

[Plasticity of bacterial genomes: pathogenicity islands and the locus of enterocyte effacement (LEE)].

PubMed

Kirsch, Petra; Jores, Jörg; Wieler, Lothar H

2004-01-01

Many bacterial virulence attributes, like toxins, adhesins, invasins, iron uptake systems, are encoded within specific regions of the bacterial genome. These in size varying regions are termed pathogenicity islands (PAIs) since they confer pathogenic properties to the respective micro-organism. Per definition PAIs are exclusively found in pathogenic strains and are often inserted near transfer-RNA genes. Nevertheless, non-pathogenic bacteria also possess foreign DNA elements that confer advantageous features, leading to improved fitness. These additional DNA elements as well as PAIs are termed genomic islands and were acquired during bacterial evolution. Significant G+C content deviation in pathogenicity islands with respect to the rest of the genome, the presence of direct repeat sequences at the flanking regions, the presence of integrase gene determinants as other mobility features,the particular insertion site (tRNA gene) as well as the observed genetic instability suggests that pathogenicity islands were acquired by horizontal gene transfer. PAIs are the fascinating proof of the plasticity of bacterial genomes. PAIs were originally described in human pathogenic Escherichia (E.) coli strains. In the meantime PAIs have been found in various pathogenic bacteria of humans, animals and even plants. The Locus of Enterocyte Effacement (LEE) is one particular widely distributed PAI of E coli. In addition, it also confers pathogenicity to the related species Citrobacter (C.) rodentium and Escherichia (E.) alvei. The LEE is an important virulence feature of several animal pathogens. It is an obligate PAI of all animal and human enteropathogenic E. coli (EPEC), and most enterohaemorrhegic E. coli (EHEC) also harbor the LEE. The LEE encodes a type III secretion system, an adhesion (intimin) that mediates the intimate contact between the bacterium and the epithelial cell, as well as various proteins which are secreted via the type III secretion system. The LEE encoded virulence features are responsible for the formation of so called attaching and effacing (AE) lesions in the intestinal epithelium. Due to its wide distribution in animal pathogens, LEE encoded antigens are suitable vaccine antigens. Acquisition and structure of the LEE pathogenicity island is the crucial point of numerous investigations. However, the evolution of the LEE, its origin and further spread in E. coli, are far from being resolved.

Changes in some lexical features of language have been associated with the onset and progression of Alzheimer's disease. Here we describe a method to extract key features from discourse transcripts, which we evaluated on non-scripted news conferences from President Ronald Reagan, who was diagnosed with Alzheimer's disease in 1994, and President George Herbert Walker Bush, who has no known diagnosis of Alzheimer's disease. Key word counts previously associated with cognitive decline in Alzheimer's disease were extracted and regression analyses were conducted. President Reagan showed a significant reduction in the number of unique words over time and a significant increase in conversational fillers and non-specific nouns over time. There was no significant trend in these features for President Bush.

Mn@Si14+: a singlet fullerene-like endohedrally doped silicon cluster.

The electronic structure of Mn@Si14(+) is determined using DFT and CASPT2/CASSCF(14,15) computations with large basis sets. The endohedrally Mn-doped Si cationic cluster has a D3h fullerene-like structure featuring a closed-shell singlet ground state with a singlet-triplet gap of ~1 eV. A strong stabilizing interaction occurs between the 3d(Mn) and the 2D-shell(Si14) orbitals, and a large amount of charge is transferred from the Si14 cage to the Mn dopant. The 3d(Mn) orbitals are filled by encapsulation, and the magnetic moment of Mn is completely quenched. Full occupation of [2S, 2P, 2D] shell orbitals by 18 delocalized electrons confers the doped Mn@Si14(+) cluster a spherically aromatic character.

Following the 2010 conference held at ETH Zurich, the 13th renowned International Mechatronics Forum Conference--Mechatronics 2012--took place from 17-19 September 2012. Held in Austria for the first time, it was jointly organized by the Johannes Kepler University and the Austrian Center for Competence in Mechatronics (ACCM). In accordance with the Local and International Organizing Committee, we opened new avenues to make this conference more attractive, particularly to industry. Mini-symposia were set up devoted to specific topics. This proved successful in attracting certain scientific communities and groups and gave the conference a broader scope and a more colourful appearance. Another successful attempt was to involve industry more strongly than in previous conferences. The conference's character was influenced by the approach and the specific mechatronic problems of the Linz area in industry, teaching and research. This concept of showcasing the local situation in mechatronics in these areas could be valuable for the future conferences; the international mechatronics community could get an overview about the different interpretations of mechatronics and could form informed opinions about different approaches. Around 150 lecturers from 23 countries around the world covered a broad spectrum of approaches to mechatronic problem solutions, of new technologies, scientific and engineering methods and methodologies. Authors of conference papers in the area of sensors and measurement technology were invited to submit extended papers for publication in this special feature in Measurement Science and Technology , which were all fully peer-reviewed. The topics of the papers that are now collected in this special feature illustrate this variety, from the application of measurement systems to microsystems and algorithms. We are grateful to the editors of Measurement Science and Technology for the opportunity to provide a glimpse of the results presented at the conference and would like to thank IOP Publishing staff for the efficient handling of the entire publication process!

The inaugural conference on Nanoscale Devices and System Integration (NDSI-2004) was held in Miami, Florida, 15-19 February, 2004. The focus of the conference was `real-life' devices and systems that have recently emerged as a result of various nanotechnology initiatives in chemistry and chemical engineering, physics, electrical engineering, materials science and engineering, biomedical engineering, computer science, robotics, and environmental science. The conference had a single session all-invited speaker format, with the presenters making the `Who's Who in Nanotechnology' list. Contributed work was showcased at a special poster session. The conference, sponsored by the Institute of Electrical and Electronics Engineers (IEEE) and the US Air Force, and endorsed by Materials Research Society (MRS), drew more than 160 participants from fourteen countries. To strengthen the connection between fundamental research and `real-life' applications, the conference featured a large number of presenters from both academia and industry. Among the participating companies were NEC, IBM, Toshiba, AMD, Samsung, Seagate, and Veeco. Nanotechnology has triggered a new wave of research collaborations between researchers from academia and industry with a broad range of specializations. Such a global approach has resulted in a number of breakthrough accomplishments. One of the main goals of this conference was to identify these accomplishments and put the novel technology initiatives and the emerging research teams on the map. Among the key nanotechnology applications demonstrated at NDSI-2004 were carbon-nanotube-based transistors, quantum computing systems, nanophotonic devices, single-molecule electronic devices and biological magnetic sources. Due to the unprecedented success of the conference, the organizing committee of NDSI has unanimously chosen to turn NDSI into an annual international nanotechnology event. The next NDSI is scheduled for 4-6 April, 2005, in Houston, Texas. Details can be found on the conference web site at http://www.nanointernational.org.

Fassina, Alessandro; Gobbin, Marco; Franz, Paolo; Marrelli, Lionello; Ruzzon, Alberto

2012-10-01

QSH (Quasi Single Helicity) states have gained a growing interest in RFP research since they show improved confinement and transport features with respect to standard discharges. However, ITBs associated with QSH states can be obtained only in a transient way, and in general with a shorter lifetime with respect to that of the QSH phase [1]. In this work the analysis has essentially the purpose of confirming, with TS data, the Te dynamics seen with the double filter, multichord SXR spectrometer in [1]: TS data allow a better spatial definition of temperature profile and a more reliable description of plasma edge. Te profile features in rising and crashing phases are determined via ensemble averaging, possible precursors of thermal crashes are identified, while q(r) behavior is studied identifying the thermal structures associated with rational surfaces.

Controlled Folding, Motional, and Constitutional Dynamic Processes of Polyheterocyclic Molecular Strands.

Barboiu, Mihail; Stadler, Adrian-Mihail; Lehn, Jean-Marie

2016-03-18

General design principles have been developed for the control of the structural features of polyheterocyclic strands and their effector-modulated shape changes. Induced defined molecular motions permit designed enforcement of helical as well as linear molecular shapes. The ability of such molecular strands to bind metal cations allows the generation of coiling/uncoiling processes between helically folded and extended linear states. Large molecular motions are produced on coordination of metal ions, which may be made reversible by competition with an ancillary complexing agent and fueled by sequential acid/base neutralization energy. The introduction of hydrazone units into the strands confers upon them constitutional dynamics, whereby interconversion between different strand compositions is achieved through component exchange. These features have relevance for nanomechanical devices. We present a morphological and functional analysis of such systems developed in our laboratories. © 2016 WILEY-VCH Verlag GmbH & Co.

Cai, Wenshan

2016-09-01

Metamaterials can be designed to exhibit extraordinarily strong chiral responses. Here we present a chiral metamaterial that produces both distinguishable linear and nonlinear features in the visible to near-infrared range. In additional to the gigantic chiral effects in the linear regime, the metamaterial demonstrates a pronounced contrast between second harmonic responses from the two circular polarizations. Linear and nonlinear images probed with circularly polarized lights show strongly defined contrast. Moreover, the chiral centers of the nanometallic structures with enhanced hotspots can be purposely opened for direct access, where emitters occupying the light-confining regions produce chiral-selective enhancement of two-photon luminescence.

Local statistics are widely utilized for quantification and image processing of OCT. For example, local mean is used to reduce speckle, local variation of polarization state (degree-of-polarization-uniformity (DOPU)) is used to visualize melanin. Conventionally, these statistics are calculated in a rectangle kernel whose size is uniform over the image. However, the fixed size and shape of the kernel result in a tradeoff between image sharpness and statistical accuracy. Superpixel is a cluster of pixels which is generated by grouping image pixels based on the spatial proximity and similarity of signal values. Superpixels have variant size and flexible shapes which preserve the tissue structure. Here we demonstrate a new superpixel method which is tailored for multifunctional Jones matrix OCT (JM-OCT). This new method forms the superpixels by clustering image pixels in a 6-dimensional (6-D) feature space (spatial two dimensions and four dimensions of optical features). All image pixels were clustered based on their spatial proximity and optical feature similarity. The optical features are scattering, OCT-A, birefringence and DOPU. The method is applied to retinal OCT. Generated superpixels preserve the tissue structures such as retinal layers, sclera, vessels, and retinal pigment epithelium. Hence, superpixel can be utilized as a local statistics kernel which would be more suitable than a uniform rectangle kernel. Superpixelized image also can be used for further image processing and analysis. Since it reduces the number of pixels to be analyzed, it reduce the computational cost of such image processing.

Design principles of hair-like structures as biological machines

PubMed Central

2018-01-01

Hair-like structures are prevalent throughout biology and frequently act to sense or alter interactions with an organism's environment. The overall shape of a hair is simple: a long, filamentous object that protrudes from the surface of an organism. This basic design, however, can confer a wide range of functions, owing largely to the flexibility and large surface area that it usually possesses. From this simple structural basis, small changes in geometry, such as diameter, curvature and inter-hair spacing, can have considerable effects on mechanical properties, allowing functions such as mechanosensing, attachment, movement and protection. Here, we explore how passive features of hair-like structures, both individually and within arrays, enable diverse functions across biology. Understanding the relationships between form and function can provide biologists with an appreciation for the constraints and possibilities on hair-like structures. Additionally, such structures have already been used in biomimetic engineering with applications in sensing, water capture and adhesion. By examining hairs as a functional mechanical unit, geometry and arrangement can be rationally designed to generate new engineering devices and ideas. PMID:29848593

The β-like globin genes are transcribed in a developmental stage specific fashion in erythroid cells. The specific transcription of globin genes is conferred by the locus control region (LCR), but the chromatin structure of the LCR in the human adult β-globin locus transcribing the δ- and β-globin genes is not clear. Here, we employed hybrid MEL cells that contain a human chromosome 11. The δ- and β-globin genes were highly transcribed in hybrid MEL/ch11 cells after transcriptional induction. LCR HS3 and HS2 were strongly occupied by erythroid specific transcriptional activators and co-factors in the induced locus. These HSs, but not HS4 and HS1, were in close proximity with the active globin genes as revealed by high resolution 3C experiments. The active features at HS3 were markedly established after transcriptional induction, while HS2 was in a relatively active conformation before the induction. Unexpectedly, HS1 did not show notable active features except histone hyperacetylation. Taken together, the LCR of the human β-globin locus transcribing the adult δ- and β-globin genes has HS specific chromatin structure. The structure at each HS, which is different from the locus transcribing the fetal globin genes, might relate to its role in transcribing the adult genes. Copyright © 2011 Elsevier Ltd.

Mitosis count is one of the factors that pathologists use to assess the risk of metastasis and survival of the patients, which are affected by the breast cancer. We investigate an application of a set of generic features and an ensemble of cascade adaboosts to the automated mitosis detection. Calculation of the features rely minimally on object-level descriptions and thus require minimal segmentation. The proposed work was developed and tested on International Conference on Pattern Recognition (ICPR) 2012 mitosis detection contest data. We plotted receiver operating characteristics curves of true positive versus false positive rates; calculated recall, precision, F-measure, and region overlap ratio measures. WE TESTED OUR FEATURES WITH TWO DIFFERENT CLASSIFIER CONFIGURATIONS: 1) An ensemble of single adaboosts, 2) an ensemble of cascade adaboosts. On the ICPR 2012 mitosis detection contest evaluation, the cascade ensemble scored 54, 62.7, and 58, whereas the non-cascade version scored 68, 28.1, and 39.7 for the recall, precision, and F-measure measures, respectively. Mostly used features in the adaboost classifier rules were a shape-based feature, which counted granularity and a color-based feature, which relied on Red, Green, and Blue channel statistics. The features, which express the granular structure and color variations, are found useful for mitosis detection. The ensemble of adaboosts performs better than the individual adaboost classifiers. Moreover, the ensemble of cascaded adaboosts was better than the ensemble of single adaboosts for mitosis detection.

The 22nd International Conference on Optical Fibre Sensors, OFS-22

2013-09-01

In October 2013, the 22nd International Conference on Optical Fibre Sensors was held in Beijing, attracting about 500 participants with 417 presentations. The conference began in 1983 in London, and in the subsequent 30 years has defined the subject. The conference is held approximately every 18 months, and rotates between three world regions: Asia/Pacific, Europe and the Americas. The conference is not 'owned' by any learned society or professional institution, but is organized by a self-sustaining international steering committee. This special feature represents the sixth occasion on which Measurement Science and Technology has published papers based on a development of a cross-section of work presented at the conference. The subject of optical fibre sensors has its beginnings in the enabling technologies of the optical fibre itself and the development of laser technologies suitable for practical use in demanding real-world applications. But the real driver for the subject in its early years was in the development of systems for defence applications, most notably for strategic-grade sea-bed hydrophone arrays for submarine detection, and the optical fibre gyroscope (the community has recently celebrated the 35th anniversary of its earliest publication) for aerospace navigation. Both applications continue to be important, but now with extensive civil applications: hydrophones for oil exploration and reservoir monitoring and management, and fibre gyroscopes for applications ranging from those requiring low cost and mass production (such as industrial robots and in agricultural machinery) to the most exotic and highest performance for space applications. The articles in this special feature exemplify the principal themes of the subject: enabling technologies, application-specific developments and systems considerations. In recent years, perhaps the most important—indeed, dominant—enabling technologies have been based on structuring of fibres: longitudinally, as in Bragg gratings, or transversely, using the science of metamaterials to produce microstructured fibres (e.g. photonic crystal fibres). In-fibre gratings continue to provide new types of sensor based on wavelength encoding, or for wavelength control for specialized sources or detection techniques. Microstructured fibres, meanwhile, provide materials with dispersion characteristics unattainable with conventional materials, as well as otherwise unfeasible physical characteristics that can be tailored to specific sensing applications. Examples of these types of technologies can be found in the following articles. The fields of application of optical fibre sensors, even if restricted to those presented at the conference, would be too lengthy to enumerate here. However, in this issue there are examples from medicine, transport, chemical sensing and electric power distribution, amongst others. An important advantage conferred by optical fibre sensors is the ability with which they can be multiplexed to form large arrays, interrogated via a single fibre, a topic that forms the subject of a number of papers in the issue. Lastly, as fibre sensors become the technology of choice in widespread applications, the issue of formal measurement standards begins to become important, and it is evidence of the maturity of the field that the subject is addressed in one of the papers published here: optical fibre sensors can now surely be said to have progressed from the physics laboratory to become a mainstream engineering reality.

Venus - Three-Dimensional Perspective View of Alpha Regio

NASA Technical Reports Server (NTRS)

1992-01-01

A portion of Alpha Regio is displayed in this three-dimensional perspective view of the surface of Venus. Alpha Regio, a topographic upland approximately 1300 kilometers across, is centered on 25 degrees south latitude, 4 degrees east longitude. In 1963, Alpha Regio was the first feature on Venus to be identified from Earth-based radar. The radar-bright area of Alpha Regio is characterized by multiple sets of intersecting trends of structural features such as ridges, troughs, and flat-floored fault valleys that, together, form a polygonal outline. Directly south of the complex ridged terrain is a large ovoid-shaped feature named Eve. The radar-bright spot located centrally within Eve marks the location of the prime meridian of Venus. Magellan synthetic aperture radar data is combined with radar altimetry to develop a three-dimensional map of the surface. Ray tracing is used to generate a perspective view from this map. The vertical scale is exaggerated approximately 23 times. Simulated color and a digital elevation map developed by the U. S. Geological Survey are used to enhance small scale structure. The simulated hues are based on color images recorded by the Soviet Venera 13 and 14 spacecraft. The image was produced at the JPL Multimission Image Processing Laboratory by Eric De Jong, Jeff Hall, and Myche McAuley, and is a single frame from the movie released at the March 5, 1991, press conference.

Constitutively active mutants of the alpha 1B-adrenergic receptor: role of highly conserved polar amino acids in receptor activation.

1996-01-01

Site-directed mutagenesis and molecular dynamics simulations of the alpha 1B-adrenergic receptor (AR) were combined to explore the potential molecular changes correlated with the transition from R (inactive state) to R (active state). Using molecular dynamics analysis we compared the structural/dynamic features of constitutively active mutants with those of the wild type and of an inactive alpha 1B-AR to build a theoretical model which defines the essential features of R and R. The results of site-directed mutagenesis were in striking agreement with the predictions of the model supporting the following hypothesis. (i) The equilibrium between R and R depends on the equilibrium between the deprotonated and protonated forms, respectively, of D142 of the DRY motif. In fact, replacement of D142 with alanine confers high constitutive activity to the alpha 1B-AR. (ii) The shift of R143 of the DRY sequence out of a conserved 'polar pocket' formed by N63, D91, N344 and Y348 is a feature common to all the active structures, suggesting that the role of R143 is fundamental for mediating receptor activation. Disruption of these intramolecular interactions by replacing N63 with alanine constitutively activates the alpha 1B-AR. Our findings might provide interesting generalities about the activation process of G protein-coupled receptors. Images PMID:8670860

The International Society of Urological Pathology held a conference on issues in testicular and penile pathology in Boston in March 2015, which included a presentation by the testis macroscopic features working group. The presentation focused on current published guidance for macroscopic handling of testicular tumors and retroperitoneal lymph node dissections with a summary of results from an online survey of members preceding the conference. The survey results were used to initiate discussions, but decisions on practice were made by expert consensus rather than voting. The importance of comprehensive assessment at the time of gross dissection with confirmation of findings by microscopic assessment was underscored. For example, the anatomic landmarks denoting the distinction of hilar soft tissue invasion (pT2) from spermatic cord invasion (pT3 category) can only be determined by careful macroscopic assessment in many cases. Other recommendations were to routinely sample epididymis, rete testis, hilar soft tissue, and tunica vaginalis in order to confirm macroscopic invasion of these structures or if not macroscopically evident, to exclude subtle microscopic invasion. Tumors 2 cm or less in greatest dimension should be completely embedded. If the tumor is >2 cm in greatest dimension, 10 blocks or a minimum of 1 to 2 additional blocks per centimeter should be taken (whichever is greater).

Structural features of influenza A virus panhandle RNA enabling the activation of RIG-I independently of 5′-triphosphate

Retinoic acid-inducible gene I (RIG-I) recognizes specific molecular patterns of viral RNAs for inducing type I interferon. The C-terminal domain (CTD) of RIG-I binds to double-stranded RNA (dsRNA) with the 5′-triphosphate (5′-PPP), which induces a conformational change in RIG-I to an active form. It has been suggested that RIG-I detects infection of influenza A virus by recognizing the 5′-triphosphorylated panhandle structure of the viral RNA genome. Influenza panhandle RNA has a unique structure with a sharp helical bending. In spite of extensive studies of how viral RNAs activate RIG-I, whether the structural elements of the influenza panhandle RNA confer the ability to activate RIG-I signaling has been poorly explored. Here, we investigated the dynamics of the influenza panhandle RNA in complex with RIG-I CTD using NMR spectroscopy and showed that the bending structure of the panhandle RNA negates the requirement of a 5′-PPP moiety for RIG-I activation.

2005-03-01

The Feature Article [1] describes how structural changes in metallic nanostructures can be followed with fast scanning tunneling microscopy (STM). The title page shows the same spot of a Ag(111) surface at room temperature, imaged with STM approximately one hour apart. Intrinsic changes to prepared nano-structures are marked as Brownian motion of vacancy islands (rectangle), coalescence of two vacancy islands (hexagon), and decay of an adatom island (circle).Karina Morgenstern is now professor at the University of Hannover. Her research is placed within the field of nanoscience and is in particular devoted to thermally activated processes of metallic nanostructures, electronically activated reactions of molecules on metallic surfaces, and water-metal interactions.The present issue of physica status solidi (b) also contains the article Apperance of copper d9 defect centres in wide-gap CdSe nanoparticles: A high-fequency EPR study by N.

Voltage Sensing in Membranes: From Macroscopic Currents to Molecular Motions

PubMed Central

Freites, J. Alfredo; Tobias, Douglas J.

2015-01-01

Voltage-sensing domains (VSDs) are integral membrane protein units that sense changes in membrane electric potential, and through the resulting conformational changes, regulate a specific function. VSDs confer voltage-sensitivity to a large superfamily of membrane proteins that includes voltage-gated Na+, K+, Ca2+, and H+ selective channels, hyperpolarization-activated cyclic nucleotide-gated channels, and voltage-sensing phosphatases. VSDs consist of four transmembrane segments (termed S1 through S4). Their most salient structural feature is the highly conserved positions for charged residues in their sequences. S4 exhibits at least three conserved triplet repeats composed of one basic residue (mostly arginine) followed by two hydrophobic residues. These S4 basic side chains participate in a state-dependent internal salt-bridge network with at least four acidic residues in S1–S3. The signature of voltage-dependent activation in electrophysiology experiments is a transient current (termed gating or sensing current) upon a change in applied membrane potential as the basic side chains in S4 move across the membrane electric field. Thus, the unique structural features of the VSD architecture allow for competing requirements: maintaining a series of stable transmembrane conformations, while allowing charge motion, as briefly reviewed here.

Origami-based mechanical metamaterials with tunable frequency band structures (Conference Presentation)

NASA Astrophysics Data System (ADS)

Yasuda, Hiromi; Pratt, Riley; Yang, Jinkyu

2017-04-01

We investigate wave dynamics in origami-based mechanical metamaterials composed of bellows-like origami structures, specifically the Tachi-Miura Polyhedron (TMP). One of the unique features of the TMP is that its structural deformations take place only along the crease lines, therefore the structure can be made of rigid plates and hinges. By utilizing this feature, we introduce linear torsional springs to model the crease lines and derive the force and displacement relationship of the TMP structure along the longitudinal direction. Our analysis shows strain softening/hardening behaviors in compression/tensile regions respectively, and the force-displacement curve can be manipulated by altering the initial configuration of the TMP (e.g., the initial folding angle). We also fabricate physical prototypes and measure the force-displacement behavior to verify our analytical model. Based on this static analysis on the TMP, we simplify the TMP structure into a linkage model, preserving the tunable strain softening/hardening behaviors. Dynamic analysis is also conducted numerically to analyze the frequency response of the simplified TMP unit cell under harmonic excitations. The simplified TMP exhibits a transition between linear and nonlinear behaviors, which depends on the amplitude of the excitation and the initial configuration. In addition, we design a 1D system composed of simplified TMP unit cells and analyze the relationship between frequency and wave number. If two different configurations of the unit cell (e.g., different initial folding angles) are connected in an alternating arrangement, the system develops frequency bandgaps. These unique static/dynamic behaviors can be exploited to design engineering devices which can handle vibrations and impact in an efficient manner.

Multimodal, 3D pathology-mimicking bladder phantom for evaluation of cystoscopic technologies (Conference Presentation)

Optical coherence tomography (OCT) and blue light cystoscopy (BLC) have shown significant potential as complementary technologies to traditional white light cystoscopy (WLC) for early bladder cancer detection. Three-dimensional (3D) organ-mimicking phantoms provide realistic imaging environments for testing new technology designs, the diagnostic potential of systems, and novel image processing algorithms prior to validation in real tissue. Importantly, the phantom should mimic features of healthy and diseased tissue as they appear under WLC, BLC, and OCT, which are sensitive to tissue color and structure, fluorescent contrast, and optical scattering of subsurface layers, respectively. We present a phantom posing the hollow shape of the bladder and fabricated using a combination of 3D-printing and spray-coating with Dragon Skin (DS) (Smooth-On Inc.), a highly elastic polymer to mimic the layered structure of the bladder. Optical scattering of DS was tuned by addition of titanium dioxide, resulting in scattering coefficients sufficient to cover the human bladder range (0.49 to 2.0 mm^-1). Mucosal vasculature and tissue coloration were mimicked with elastic cord and red dye, respectively. Urethral access was provided through a small hole excised from the base of the phantom. Inserted features of bladder pathology included altered tissue color (WLC), fluorescence emission (BLC), and variations in layered structure (OCT). The phantom surface and underlying material were assessed on the basis of elasticity, optical scattering, layer thicknesses, and qualitative image appearance. WLC, BLC, and OCT images of normal and cancerous features in the phantom qualitatively matched corresponding images from human bladders.

Summary Primate motor cortex projects to spinal interneurons and motor neurons, suggesting that motor cortex activity may be dominated by muscle-like commands. Extensive observations during reaching lend support to this view, but evidence remains ambiguous and much-debated. To provide a different perspective, we employed a novel behavioral paradigm that affords extensive comparison between time-evolving neural and muscle activity. We found that single motor cortex neurons displayed many muscle-like properties, but the structure of population activity was not muscle-like. Unlike muscle activity, neural activity was structured to avoid ‘tangling’: moments where similar activity patterns led to dissimilar future patterns. Avoidance of tangling was present across tasks and species. Network models revealed a potential reason for this consistent feature: low tangling confers noise robustness. Finally, we were able to predict motor cortex activity from muscle activity alone, by leveraging the hypothesis that muscle-like commands are embedded in additional structure that yields low tangling.

Scanning Probe Recognition Microscopy is a new scanning probe capability under development within our group to reliably return to and directly interact with a specific nanobiological feature of interest. In previous work, we have successfully recognized and classified tubular versus globular biological objects from experimental atomic force microscope images using a method based on normalized central moments [ref. 1]. In this paper we extend this work to include recognition schemes appropriate for cellular and sub-cellular structures. Globular cells containing tubular actin filaments are under investigation. Thus there are differences in external/internal shapes and scales. Continuous Wavelet Transform with a differential Gaussian mother wavelet is employed for multi- scale analysis. [ref. 1] Q. Chen, V.

Paralogous enzymes arise from gene duplication events that confer a novel function, although it is unclear how cross-reaction between the original and duplicate protein interaction network is minimized. We investigated HPr:EIsugar and NPr:EINtr, the initial complexes of paralogous phosphorylation cascades involved in sugar import and nitrogen regulation in bacteria, respectively. Although the HPr:EIsugar interaction has been well characterized, involving multiple complexes and transient interactions, the exact nature of the NPr:EINtr complex was unknown. We set out to identify the key features of the interaction by performing binding assays and elucidating the structure of NPr in complex with the phosphorylation domainmore » of EINtr (EINNtr), using a hybrid approach involving X-ray, homology, and sparse nuclear magnetic resonance. We found that the overall fold and active-site structure of the two complexes are conserved in order to maintain productive phosphorylation, however, the interface surface potential differs between the two complexes, which prevents cross-reaction.« less

EMAG2013 was certainly the biggest EMAG conference I can remember in my twenty years of going to EMAG conferences. We had a total of about 180 scientific delegates, not including exhibitors. The conference also benefited from the York conference centre allowing us to integrate the scientific sessions, refreshments and exhibition in one building. This all made for a very vibrant and focused conference. The quality of the presentations was again very high and judging by many of the student talks given, there is plenty of hope for an excellent future for electron microscopy in the UK. A unique feature of this conference was a chance to organise a session to commemorate the 80th year of one of the pioneers of electron microscopy in the UK, Professor Archie Howie. An excellent symposium was organised in his honour by one of his former students, Professor Pratibha Gai of the University of York. This was dedicated to one field that he made some important initial contributions to: in-situ microscopy. The symposium gave a depth and breadth of overview to this field unusual at an EMAG conference, with speakers from the UK, Europe, Japan and the USA and gave a real taste of some of the possibilities in the latest instruments to observe real materials at work at nanometre or even atomic resolution. Professor Howie himself gave a highly entertaining retrospective of his time working in microscopy from the 1950s until the present in his talk after the conference dinner on the Thursday evening at the excellent York National Railway Museum. We also had excellent plenary lectures from Professor Wolfgang Baumeister on a topic perhaps novel to many at EMAG, TEM in Structural Biology; from Professor Prathibha Gai on atomic resolution in-situ studies of chemical reactions in the TEM; and Professor Archie Howie discussing some of the important current open questions in TEM and STEM. This proceedings therefore presents a snapshot of a broad cross-section of the exciting work going on in electron microscopy in 2013. As always, the papers are ordered thematically according to the sessions organised at the conference. As ever, I have a great debt of gratitude to my fellow EMAG committee members who chaired the various sessions and who, together with the programme chair, Dr Cate Ducati of the University of Cambridge helped to put together such an excellent programme. I also gratefully acknowledge the many hours invested by Professor Pete Nellist of the University of Oxford who then edited this proceedings and ensured that the peer review and revision process ran as smoothly as possible. Finally, I hope that you enjoy reading the contributions made by many to this excellent conference. Dr Ian MacLaren, Chair of the Electron Microscopy and Analysis Group

Preface: Special issue featuring papers from the International Conference on Nonequilibrium Carrier Dynamics in Semiconductors

2004-02-01

The International Conference on Nonequilibrium Carrier Dynamics in Semiconductors (HCIS-13) celebrates 30 years since it first took place in Modena. Nonequilibrium dynamics of charge carriers, pioneered by the hot-electron concept, is an important issue for understanding electro-optic transport properties in semiconductor materials and structures. In these 30 years several topics have matured, and new ones have emerged thus fertilizing the field with a variety of physical problems and new ideas. The history of the conference is summarized in the opening paper `30 years of HCIS'. The future of the conference seems secure considering the continued lively interest of the participants. The conference addressed eleven major topics which constitute the backbone of the proceedings and are summarized as follows: carrier transport in low dimensional and nanostructure systems, nonequilibrium carriers in superlattices and devices, small devices and related phenomena, carrier dynamics and fluctuations, carrier quantum dynamics, coherent/incoherent carrier dynamics of optical excitations and ultra-fast optical phenomena, nonlinear optical effects, transport in organic matter, semiconductor-based spintronics, coherent dynamics in solid state systems for quantum processing and communication, novel materials and devices. Nanometric space scale and femtosecond time scale represent the ultimate domains of theoretical, experimental and practical interest. Traditional fields such as bulk properties, quantum transport, fluctuations and chaotic phenomena, etc, have received thorough and continuous attention. Emerging fields from previous conferences, such as quantum processing and communication, have been better assessed. New fields, such as spintronics and electron transport in organic matter, have appeared for the first time. One plenary talk, 11 invited talks, 230 submitted abstracts covering all these topics constituted a single-session conference. Following scientific selection through the Advisory and Program Committees and peer review, 162 papers were selected for publication by the Institute of Physics Publishing in this special issue of Semiconductor Science and Technology. The financial support that allowed conference organization and helped researchers with budget difficulties to attend came from the following institutions which are gratefully acknowledged: Office of Naval Research (ONR), Defense Advanced Research Project Agency (DARPA), Office of Naval Research International Field Office (ONRIFO), International Union of Pure and Applied Physics (IUPAP), Italian Ministry of Education University and Research (MIUR), National Institute for the Physics of Matter (INFM), University of Modena and Reggio Emilia, Dipartimento di Ingegneria dell’ Innovazione of the Lecce University. Finally, sincere thanks are addressed to the technical staff who provided assistance during the conference: G Angelone, M Benassi, F Grossi, M Leuzzi, A Magnani, S Montanto, L Zagni and D Zanfi. The staff of the University Press Office together with F Goggi and N Minto are acknowledged for their excellent job in printing the conference documents.

Communication within cells relies on a few protein nodes called hubs, which organize vast interactomes with many partners. Frequently, hub proteins are intrinsically disordered conferring multi-specificity and dynamic communication. Conversely, folded hub proteins may organize networks using disordered partners. In this work, the structure of the RST domain, a unique folded hub, is solved by nuclear magnetic resonance spectroscopy and small-angle X-ray scattering, and its complex with a region of the transcription factor DREB2A is provided through data-driven HADDOCK modeling and mutagenesis analysis. The RST fold is unique, but similar structures are identified in the PAH (paired amphipathic helix), TAFH (TATA-box-associated factor homology), and NCBD (nuclear coactivator binding domain) domains. We designate them as a group the αα hubs, as they share an αα-hairpin super-secondary motif, which serves as an organizing platform for malleable helices of varying topology. This allows for partner adaptation, exclusion, and selection. Our findings provide valuable insights into structural features enabling signaling fidelity. Copyright © 2018 Elsevier Ltd.

Structural Analysis of the Synaptic Protein Neuroligin and Its β-Neurexin Complex: Determinants for Folding and Cell Adhesion

SUMMARY The neuroligins are postsynaptic cell adhesion proteins whose associations with presynaptic neurexins participate in synaptogenesis. Mutations in the neuroligin and neurexin genes appear to be associated with autism and mental retardation. The crystal structure of a neuroligin reveals features not found in its catalytically active relatives, such as the fully hydrophobic interface forming the functional neuroligin dimer; the conformations of surface loops surrounding the vestigial active center; the location of determinants that are critical for folding and processing; and the absence of a macromolecular dipole and presence of an electronegative, hydrophilic surface for neurexin binding. The structure of a β-neurexin-neuroligin complex reveals the precise orientation of the bound neurexin and, despite a limited resolution, provides substantial information on the Ca2+-dependent interactions network involved in trans-synaptic neurexin-neuroligin association. These structures exemplify how an α/β-hydrolase fold varies in surface topography to confer adhesion properties and provide templates for analyzing abnormal processing or recognition events associated with autism.

SUMMARY Microvascular endothelial cells (ECs) within different tissues are endowed with distinct but as yet unrecognized structural, phenotypic, and functional attributes. We devised EC purification, cultivation, profiling, and transplantation models that establish tissue-specific molecular libraries of ECs devoid of lymphatic ECs or parenchymal cells. These libraries identify attributes that confer ECs with their organotypic features. We show that clusters of transcription factors, angiocrine growth factors, adhesion molecules, and chemokines are expressed in unique combinations by ECs of each organ. Furthermore, ECs respond distinctly in tissue regeneration models, hepatectomy, and myeloablation. To test the data set, we developed a transplantation model that employs generic ECs differentiated from embryonic stem cells. Transplanted generic ECs engraft into regenerating tissues and acquire features of organotypic ECs. Collectively, we demonstrate the utility of informational databases of ECs toward uncovering the extravascular and intrinsic signals that define EC heterogeneity. These factors could be exploited therapeutically to engineer tissue-specific ECs for regeneration. PMID:23871589

Oncogene-like induction of cellular invasion from centrosome amplification

Centrosome amplification has long been recognized as a feature of human tumors, however its role in tumorigenesis remains unclear1. Centrosome amplification is poorly tolerated by non-transformed cells, and, in the absence of selection, extra centrosomes are spontaneously lost2. Thus, the high frequency of centrosome amplification, particularly in more aggressive tumors3, raises the possibility that extra centrosomes could, in some contexts, confer advantageous characteristics that promote tumor progression. Using a three-dimensional model system and other approaches to culture human mammary epithelial cells, we find that centrosome amplification triggers cell invasion. This invasive behavior is similar to that induced by overexpression of the breast cancer oncogene ErbB24 and indeed enhances invasiveness triggered by ErbB2. We show that, through increased centrosomal microtubule nucleation, centrosome amplification increases Rac1 activity, which disrupts normal cell-cell adhesion and promotes invasion. These findings demonstrate that centrosome amplification, a structural alteration of the cytoskeleton, can promote features of malignant transformation. PMID:24739973

Many health sciences librarians as well as other professionals attend conferences on a regular basis. This study sought to link an innovative peer review process of presented research papers to long-term conference outcomes in the peer-reviewed professional journal literature. An evidence-based conference included a proof-of-concept study to gauge the long-term outcomes from research papers presented during the program. Real-time peer review recommendations from the conference were linked to final versions of articles published in the peer-reviewed literature. The real-time peer review feedback served as the basis for further mentoring to guide prospective authors toward publishing their research results. These efforts resulted in the publication of two of the four research papers in the peer-viewed literature. A third presented paper appeared in a blog because the authors wanted to disseminate their findings more quickly than through the journal literature. The presenters of the fourth paper never published their study. Real-time peer review from this study can be adapted to other professional conferences that include presented research papers.

Enterovirus 71 (EV71) is one of the most virulent enteroviruses, but the specific molecular features that enhance its ability to disseminate in humans remain unknown. We analyzed the genomic features of EV71 in an immunocompromised host with disseminated disease according to the different sites of infection. Comparison of five full-length genomes sequenced directly from respiratory, gastrointestinal, nervous system, and blood specimens revealed three nucleotide changes that occurred within a five-day period: a non-conservative amino acid change in VP1 located within the BC loop (L97R), a region considered as an immunogenic site and possibly important in poliovirus host adaptation; a conservative amino acid substitution in protein 2B (A38V); and a silent mutation in protein 3D (L175). Infectious clones were constructed using both BrCr (lineage A) and the clinical strain (lineage C) backgrounds containing either one or both non-synonymous mutations. In vitro cell tropism and competition assays revealed that the VP197 Leu to Arg substitution within the BC loop conferred a replicative advantage in SH-SY5Y cells of neuroblastoma origin. Interestingly, this mutation was frequently associated in vitro with a second non-conservative mutation (E167G or E167A) in the VP1 EF loop in neuroblastoma cells. Comparative models of these EV71 VP1 variants were built to determine how the substitutions might affect VP1 structure and/or interactions with host cells and suggest that, while no significant structural changes were observed, the substitutions may alter interactions with host cell receptors. Taken together, our results show that the VP1 BC loop region of EV71 plays a critical role in cell tropism independent of EV71 lineage and, thus, may have contributed to dissemination and neurotropism in the immunocompromised patient.

Clustered regularly interspaced short palindromic repeats (CRISPR) are inheritable genetic elements of a variety of archaea and bacteria and indicative of the bacterial ecological adaptation, conferring acquired immunity against invading foreign nucleic acids. Shigella is an important pathogen for anthroponosis. This study aimed to analyze the features of Shigella CRISPR structure and classify the spacers through bioinformatics approach. Among 107 Shigella, 434 CRISPR structure loci were identified with two to seven loci in different strains. CRISPR-Q1, CRISPR-Q4 and CRISPR-Q5 were widely distributed in Shigella strains. Comparison of the first and last repeats of CRISPR1, CRISPR2 and CRISPR3 revealed several base variants and different stem-loop structures. A total of 259 cas genes were found among these 107 Shigella strains. The cas gene deletions were discovered in 88 strains. However, there is one strain that does not contain cas gene. Intact clusters of cas genes were found in 19 strains. From comprehensive analysis of sequence signature and BLAST and CRISPRTarget score, the 708 spacers were classified into three subtypes: Type I, Type II and Type III. Of them, Type I spacer referred to those linked with one gene segment, Type II spacer linked with two or more different gene segments, and Type III spacer undefined. This study examined the diversity of CRISPR/cas system in Shigella strains, demonstrated the main features of CRISPR structure and spacer classification, which provided critical information for elucidation of the mechanisms of spacer formation and exploration of the role the spacers play in the function of the CRISPR/cas system.

2015-01-01

The 13th Anglo-French Physical Acoustics Conference (AFPAC) was held at Selsdon Park Hotel, Croydon near London, United Kingdom, on 15-17 January 2014. The venue was an excellent location to exchange ideas, regardless whether this happened in the conference room, over lunch at the drinks reception in the conservatory, in the oak panelled bar after the conference dinner or in the local pub next door. Over 45 papers were presented at the conference. There were over 60 delegates from institutions covering four countries. The invited speakers from the French side shared their knowledge about the generation of sound from supersonic jets (Prof Christophe Bailly, École Centrale de Lyon) and the application of ultrasonic microscropy in the nuclear industry (Prof Gilles Despaux, Université de Montpellier). The UK invited speakers included Prof Malcolm Povey (University of Leeds), who talked about characterisation of the nucleation of crystals using ultrasound, and Prof Bruce Drinkwater (University of Bristol), who captured the audience by speaking about "ultrasonic lassos" and ultrasonic particle manipulation. There was a strong representation of laser ultrasonics at the meeting with scientific considerations of problems and applications that range from the macro to the nanoscale. There were also numerous papers on the interaction of elastic and acoustic waves with complex materials and scattering of these waves by materials such as foams or cavitating liquids. Presentations on biomedical applications are increasingly being featured at AFPAC meetings. Talks this year covered topics such as imaging and high-intensity focused ultrasound for therapeutic applications. Finally, there were also several contributions from the field of Non-Destructive Evaluation (NDE) and Structural Health Monitoring (SHM) with talks ranging from the determination of the properties of in vivo wood to ultrasonic scattering techniques and tomographic reconstructions to recover the size and shape of defects in pipes and plates. The UK organising committee was particularly happy to welcome the many French contributors that travelled to Croydon and would like to thank Alain Lhémery and the Société Française d'Acoustique (SFA) for publicising the event in France. We are happy to announce that many of the presented papers will be published in the conference proceedings in Journal of Physics: Conference Series. We would also like to draw the reader's attention to the upcoming 14th AFPAC conference that is scheduled to take place on 14-16 of January 2015 in Fréjus, France.

Co-Conserved MAPK Features Couple D-Domain Docking Groove to Distal Allosteric Sites via the C-Terminal Flanking Tail

Mitogen activated protein kinases (MAPKs) form a closely related family of kinases that control critical pathways associated with cell growth and survival. Although MAPKs have been extensively characterized at the biochemical, cellular, and structural level, an integrated evolutionary understanding of how MAPKs differ from other closely related protein kinases is currently lacking. Here, we perform statistical sequence comparisons of MAPKs and related protein kinases to identify sequence and structural features associated with MAPK functional divergence. We show, for the first time, that virtually all MAPK-distinguishing sequence features, including an unappreciated short insert segment in the β4-β5 loop, physically couple distal functional sites in the kinase domain to the D-domain peptide docking groove via the C-terminal flanking tail (C-tail). The coupling mediated by MAPK-specific residues confers an allosteric regulatory mechanism unique to MAPKs. In particular, the regulatory αC-helix conformation is controlled by a MAPK-conserved salt bridge interaction between an arginine in the αC-helix and an acidic residue in the C-tail. The salt-bridge interaction is modulated in unique ways in individual sub-families to achieve regulatory specificity. Our study is consistent with a model in which the C-tail co-evolved with the D-domain docking site to allosterically control MAPK activity. Our study provides testable mechanistic hypotheses for biochemical characterization of MAPK-conserved residues and new avenues for the design of allosteric MAPK inhibitors. PMID:25799139

The 1993 conference hosted a wide variety of presentations and activities. Continuing the NCBPS tradition, we offered technical physics presentations, tours of physics research facilities, a career and educational fair, technical presentations by students, dinner speakers and a dance. New this, year were the interactive workshops (described in the section entitled ``New Features``). We included a ``celebrity`` speaker -- Col. Fred Gregory, an African-American NASA astronaut This presentation was featured on the local TV news. There were two last minute changes to the program They included: the replacement of Howard Adams and Tim Childs with Sylvia Wilson and Warren Buck,more » respectively. Howard Adams was ill and canceled a couple of days in advance. He recommended Sylvia Wilson, also of the GEM Program, as a replacement speaker. The substitution worked quite well, especially since our program was lacking in female speakers. Tim Childs missed his flight so Warren Buck, who attended the conference as an observer, generously filled in at the last minute. We ran a brief survey of the corporate, governmental and educational recruiters who were part of our Career/Educational Fair. Of 15 recruiters, 9 responded to the survey. All who responded said they were pleased with the conference arrangements. See Appendix C for the complete results of the Survey for Recruiters.« less

Discovering rules for protein-ligand specificity using support vector inductive logic programming.

Kelley, Lawrence A; Shrimpton, Paul J; Muggleton, Stephen H; Sternberg, Michael J E

2009-09-01

Structural genomics initiatives are rapidly generating vast numbers of protein structures. Comparative modelling is also capable of producing accurate structural models for many protein sequences. However, for many of the known structures, functions are not yet determined, and in many modelling tasks, an accurate structural model does not necessarily tell us about function. Thus, there is a pressing need for high-throughput methods for determining function from structure. The spatial arrangement of key amino acids in a folded protein, on the surface or buried in clefts, is often the determinants of its biological function. A central aim of molecular biology is to understand the relationship between such substructures or surfaces and biological function, leading both to function prediction and to function design. We present a new general method for discovering the features of binding pockets that confer specificity for particular ligands. Using a recently developed machine-learning technique which couples the rule-discovery approach of inductive logic programming with the statistical learning power of support vector machines, we are able to discriminate, with high precision (90%) and recall (86%) between pockets that bind FAD and those that bind NAD on a large benchmark set given only the geometry and composition of the backbone of the binding pocket without the use of docking. In addition, we learn rules governing this specificity which can feed into protein functional design protocols. An analysis of the rules found suggests that key features of the binding pocket may be tied to conformational freedom in the ligand. The representation is sufficiently general to be applicable to any discriminatory binding problem.

On the contributions of topological features to transcriptional regulatory network robustness

PubMed Central

2012-01-01

Background Because biological networks exhibit a high-degree of robustness, a systemic understanding of their architecture and function requires an appraisal of the network design principles that confer robustness. In this project, we conduct a computational study of the contribution of three degree-based topological properties (transcription factor-target ratio, degree distribution, cross-talk suppression) and their combinations on the robustness of transcriptional regulatory networks. We seek to quantify the relative degree of robustness conferred by each property (and combination) and also to determine the extent to which these properties alone can explain the robustness observed in transcriptional networks. Results To study individual properties and their combinations, we generated synthetic, random networks that retained one or more of the three properties with values derived from either the yeast or E. coli gene regulatory networks. Robustness of these networks were estimated through simulation. Our results indicate that the combination of the three properties we considered explains the majority of the structural robustness observed in the real transcriptional networks. Surprisingly, scale-free degree distribution is, overall, a minor contributor to robustness. Instead, most robustness is gained through topological features that limit the complexity of the overall network and increase the transcription factor subnetwork sparsity. Conclusions Our work demonstrates that (i) different types of robustness are implemented by different topological aspects of the network and (ii) size and sparsity of the transcription factor subnetwork play an important role for robustness induction. Our results are conserved across yeast and E Coli, which suggests that the design principles examined are present within an array of living systems. PMID:23194062

Molecular characterization of the staphylococcal multidrug resistance export protein QacC.

Paulsen, I T; Brown, M H; Dunstan, S J; Skurray, R A

1995-01-01

The QacC polypeptide is a member of a family of small membrane proteins which confer resistance to toxic compounds. The staphylococcal qacC gene confers resistance to toxic organic cations via proton-dependent export. The membrane topology of the QacC polypeptide was investigated by constructing and analyzing a series of qacC-phoA and qacC-lacZ fusions. From these analyses, most of the predicted features of the QacC protein were verified, although data regarding the possible orientation of the COOH region were not conclusive. The role of the sole cysteine residue, Cys-42, in QacC was studied by using the sulfhydryl reagent N-ethylmaleimide and site-directed mutagenesis. N-Ethylmaleimide was shown to inhibit qacC-mediated ethidium export. Multiple amino acid substitutions were made for Cys-42, and mutations at this location had various effects on resistance specificity. This suggests that the Cys-42 residue may be located near a region of QacC that is involved in substrate recognition. Mutagenesis of conserved residues in QacC indicated that Tyr-59 and Trp-62 also play an essential structural or functional role in QacC. PMID:7751293

Voltage Sensing in Membranes: From Macroscopic Currents to Molecular Motions.

PubMed

Freites, J Alfredo; Tobias, Douglas J

2015-06-01

Voltage-sensing domains (VSDs) are integral membrane protein units that sense changes in membrane electric potential, and through the resulting conformational changes, regulate a specific function. VSDs confer voltage-sensitivity to a large superfamily of membrane proteins that includes voltage-gated Na[Formula: see text], K[Formula: see text], Ca[Formula: see text] ,and H[Formula: see text] selective channels, hyperpolarization-activated cyclic nucleotide-gated channels, and voltage-sensing phosphatases. VSDs consist of four transmembrane segments (termed S1 through S4). Their most salient structural feature is the highly conserved positions for charged residues in their sequences. S4 exhibits at least three conserved triplet repeats composed of one basic residue (mostly arginine) followed by two hydrophobic residues. These S4 basic side chains participate in a state-dependent internal salt-bridge network with at least four acidic residues in S1-S3. The signature of voltage-dependent activation in electrophysiology experiments is a transient current (termed gating or sensing current) upon a change in applied membrane potential as the basic side chains in S4 move across the membrane electric field. Thus, the unique structural features of the VSD architecture allow for competing requirements: maintaining a series of stable transmembrane conformations, while allowing charge motion, as briefly reviewed here.

Recent advances of pyrrolopyridines derivatives: a patent and literature review.

PubMed

El-Gamal, Mohammed I; Anbar, Hanan S

2017-05-01

Several pyrrolopyridines or azaindoles have been reported in the literature as biologically-active molecules. Most of them are anticancer agents, and few possess other therapeutic effects. Areas covered: The most recent biologically-active pyrrolopyridine derivatives have been reviewed from the patents and research articles published from 2010 to the mid of 2016. Their structural and biological features have been explained. In general, the pyrrolopyridine scaffold mimics the purine ring of the ATP molecule. So the well-designed pyrrolopyridine analogues can successfully act as kinase inhibitors for treatment of cancer and/or other diseases. The most successful pyrrolopyridine derivative that is currently used in the market is vemurafenib, which is used for treatment of melanoma. Its chemical and biological features have been reviewed and explained. Expert opinion: The heterocyclic pyrrolopyridine nucleus mimics the purine ring of ATP. So they can work as inhibitors of the kinase at hinge region. Due to the structural similarity with ATP, these pyrrolopyridine derivatives are estimated to be non-selective kinase inhibitors. The selectivity is conferred mainly from the different substituents attached to the azaindole nucleus. More details are presented in the 'Expert Opinion' section at the end of this article. This section covers the chemistry and the biological properties of therapeutically-efficient pyrrolopyridine-possessing compounds.

New Insights into the In Silico Prediction of HIV Protease Resistance to Nelfinavir

The Human Immunodeficiency Virus type 1 protease enzyme (HIV-1 PR) is one of the most important targets of antiretroviral therapy used in the treatment of AIDS patients. The success of protease-inhibitors (PIs), however, is often limited by the emergence of protease mutations that can confer resistance to a specific drug, or even to multiple PIs. In the present study, we used bioinformatics tools to evaluate the impact of the unusual mutations D30V and V32E over the dynamics of the PR-Nelfinavir complex, considering that codons involved in these mutations were previously related to major drug resistance to Nelfinavir. Both studied mutations presented structural features that indicate resistance to Nelfinavir, each one with a different impact over the interaction with the drug. The D30V mutation triggered a subtle change in the PR structure, which was also observed for the well-known Nelfinavir resistance mutation D30N, while the V32E exchange presented a much more dramatic impact over the PR flap dynamics. Moreover, our in silico approach was also able to describe different binding modes of the drug when bound to different proteases, identifying specific features of HIV-1 subtype B and subtype C proteases.

Improved understanding of electromagnetic scattering by nonspherical particles is important to many science and engineering disciplines and was the subject of the Conference on Light Scattering by Nonspherical Particles: Theory, Measurements, and Applications. The conference was held 29 September-1 October 1998 at the Goddard Institute for Space Studies in New York City and brought together 115 participants from 18 countries. The main objective of the conference was to highlight and summarize the rapid advancements in the field, including numerical methods for computing the single and multiple scattering of electromagnetic radiation by nonspherical and heterogeneous particles, measurement approaches, knowledge of characteristic features in scattering patterns, retrieval and remote sensing techniques, nonspherical particle sizing, and various practical applications. The conference consisted of twelve oral and one poster sessions. The presentations were loosely grouped based on broad topical categories. In each of these categories invited review talks highlighted and summarized specific active areas of research. To ensure a high-quality conference, all abstracts submitted had been reviewed by members of the Scientific Organizing Committee for technical merit and content. The conference program was published in the June 1998 issue of the Bulletin of the American Meteorological Society and is available on the World Wide Web at http://www.giss.nasa.gov/-crmim/conference/program.html. Authors of accepted papers and review presentations contributed to a volume of preprints published by the American Meteorological Society' and distributed to participants at the conference.

In the past decade, Medical Informatics (MI) and Bioinformatics (BI) have converged towards a new discipline, called Biomedical Informatics (BMI) bridging informatics methods across the spectrum from genomic research to personalized medicine and global healthcare. This convergence still raises challenging research questions which are being addressed by researchers internationally, which in turn raises the question of how biomedical informatics publications reflect the contributions from around the world in documenting the research. To analyse the worldwide participation of biomedical informatics researchers from professional groups and societies in the best-known scientific conferences in the field. The analysis is focused on their geographical affiliation, but also includes other features, such as the impact and recognition of the conferences. We manually collected data about authors of papers presented at three major MI conferences: Medinfo, MIE and the AMIA symposium. In addition, we collected data from a BI conference, ISMB, as a comparison. Finally, we analyzed the impact and recognition of these conferences within their scientific contexts. Data indicate a predominance of local authors at the regional conferences (AMIA and MIE), whereas other conferences with a world-wide scope (Medinfo and ISMB) had broader participation. Our analysis shows that the influence of these conferences beyond the discipline remains somewhat limited. Our results suggest that for BMI to be recognized as a broad discipline, both in the geographical and scientific sense, it will need to extend the scope of collaborations and their interdisciplinary impacts worldwide.

The 13th ERS Lung Science Conference (LSC) was organised to bring academics together from all over the world to present and discuss the latest developments regarding lung infection and immunity. The conference took place in breathtaking Estoril, Portugal; however, it wasn't the beautiful surroundings that were our main motivation to attend, but instead the scientific merit of the conference and the chance to create new scientific collaborations. The scientific programme [1] was packed with the most up-to-date content in the field of lung infection and immunity and included some of the top researchers within this exciting area. Moreover, the convenient size of the LSC offered the opportunity to renew and intensify friendships and collaborations. In particular, for researchers at the start of their career, this is a great feature and we therefore warmly recommend the LSC to ERS Juniors Members!

This second and final instalment of the conference report from International Congress on Infectious Diseases 2014 follows on from part one, published in Future Microbiology (volume 9/issue 11). The 16th International Congress on Infectious Diseases was held in Cape Town this year, marking the return of the conference to Africa for the first time in 22 years. While infectious diseases such as malaria, tuberculosis and HIV--all still prevalent in the African healthcare landscape--dominated the program, the conference featured several important sessions on fungal infection and a significant number of posters devoted to this critical medical area. Within the context of the rise of antimicrobial resistance, now identified by WHO as one of the three greatest threats to human health, came the message that resistance is not limited to antimicrobials, but that antifungal resistance is also a significant and emerging threat worldwide.

The morbidity and mortality (M&M) conference is a vital event that can affect medical education, quality improvement, and peer review in academic departments. Historically, M&M conferences have emphasized cases that highlight diagnostic uncertainty or complex management conundrums. In this report, the authors describe the development, pilot, and refinement of a systems-based M&M conference model that combines the educational and clinical missions of improving quality and patient safety in the University of Colorado Department of Medicine. In 2011, a focused taskforce completed a literature review that informed the development of a framework for the redesigned systems-based M&M conference. The new model included a restructured monthly conference, longitudinal curriculum for residents, and formal channels for interaction with clinical effectiveness departments. Each conference features an in-depth discussion of an adverse event using specific quality improvement tools. Areas for improvement and suggested action items are identified during the conference and delegated to the relevant clinical departments. The new process has enabled the review of 27 adverse events over two years. Sixty-three action items were identified, and 33 were pursued. An average of 50 to 60 individuals participate in each conference, including interprofessional and interdisciplinary colleagues. Resident and faculty feedback regarding the new format has been positive, and other departments are starting to adopt this model. A more robust process for identifying and selecting cases to discuss is needed, as is a stable, sufficient mechanism to manage the improvement initiatives that come out of each conference.

A magnetic nanocomposite film with the capability of reversibly collecting functionalized magnetic particles was fabricated by simultaneously imposing two orthogonal stimuli (electrical and magnetic). We demonstrate that cathodic codeposition of chitosan and Fe3O4 nanoparticles while simultaneously applying a magnetic field during codeposition can (i) organize structure, (ii) confer magnetic properties, and (iii) yield magnetic films that can perform reversible collection/assembly functions. The magnetic field triggered the self-assembly of Fe3O4 nanoparticles into hierarchical "chains" and "fibers" in the chitosan film. For controlled magnetic properties, the Fe3O4-chitosan film was electrodeposited in the presence of various strength magnetic fields and different deposition times. The magnetic properties of the resulting films should enable broad applications in complex devices. As a proof of concept, we demonstrate the reversible capture and release of green fluorescent protein (EGFP)-conjugated magnetic microparticles by the magnetic chitosan film. Moreover, antibody-functionalized magnetic microparticles were applied to capture cells from a sample, and these cells were collected, analyzed, and released by the magnetic chitosan film, paving the way for applications such as reusable biosensor interfaces (e.g., for pathogen detection). To our knowledge, this is the first report to apply a magnetic field during the electrodeposition of a hydrogel to generate magnetic soft matter. Importantly, the simple, rapid, and reagentless fabrication methodologies demonstrated here are valuable features for creating a magnetic device interface.

Zebrafish hox paralogue group 2 genes function redundantly as selector genes to pattern the second pharyngeal arch.

PubMed

Hunter, Michael P; Prince, Victoria E

2002-07-15

The pharyngeal arches are one of the defining features of the vertebrates, with the first arch forming the mandibles of the jaw and the second forming jaw support structures. The cartilaginous elements of each arch are formed from separate migratory neural crest cell streams, which derive from the dorsal aspect of the neural tube. The second and more posterior crest streams are characterized by specific Hox gene expression. The zebrafish has a larger overall number of Hox genes than the tetrapod vertebrates, as the result of a duplication event in its lineage. However, in both zebrafish and mouse, there are just two members of Hox paralogue group 2 (PG2): Hoxa2 and Hoxb2. Here, we show that morpholino-mediated "knock-down" of both zebrafish Hox PG2 genes results in major defects in second pharyngeal arch cartilages, involving replacement of ventral elements with a mirror-image duplication of first arch structures, and accompanying changes to pharyngeal musculature. In the mouse, null mutants of Hoxa2 have revealed that this single Hox gene is required for normal second arch patterning. By contrast, loss-of-function of either zebrafish Hox PG2 gene individually has no phenotypic consequence, showing that these two genes function redundantly to confer proper pattern to the second pharyngeal arch. We have also used hoxb1a mis-expression to induce localized ectopic expression of zebrafish Hox PG2 genes in the first arch; using this strategy, we find that ectopic expression of either Hox PG2 gene can confer second arch identity onto first arch structures, suggesting that the zebrafish Hox PG2 genes act as "selector genes." 2002 Elsevier Science (USA).

Role of the Conserved Disulfide Bridge in Class A Carbapenemases*

2016-01-01

Some members of the class A β-lactamase family are capable of conferring resistance to the last resort antibiotics, carbapenems. A unique structural feature of these clinically important enzymes, collectively referred to as class A carbapenemases, is a disulfide bridge between invariant Cys69 and Cys238 residues. It was proposed that this conserved disulfide bridge is responsible for their carbapenemase activity, but this has not yet been validated. Here we show that disruption of the disulfide bridge in the GES-5 carbapenemase by the C69G substitution results in only minor decreases in the conferred levels of resistance to the carbapenem imipenem and other β-lactams. Kinetic and circular dichroism experiments with C69G-GES-5 demonstrate that this small drop in antibiotic resistance is due to a decline in the enzyme activity caused by a marginal loss of its thermal stability. The atomic resolution crystal structure of C69G-GES-5 shows that two domains of this disulfide bridge-deficient enzyme are held together by an intensive hydrogen-bonding network. As a result, the protein architecture and imipenem binding mode remain unchanged. In contrast, the corresponding hydrogen-bonding networks in NMCA, SFC-1, and SME-1 carbapenemases are less intensive, and as a consequence, disruption of the disulfide bridge in these enzymes destabilizes them, which causes arrest of bacterial growth. Our results demonstrate that the disulfide bridge is essential for stability but does not play a direct role in the carbapenemase activity of the GES family of β-lactamases. This would likely apply to all other class A carbapenemases given the high degree of their structural similarity. PMID:27590339

The material and biological characteristics of osteoinductive calcium phosphate ceramics

Tang, Zhurong; Li, Xiangfeng; Tan, Yanfei

2018-01-01

Abstract The discovery of osteoinductivity of calcium phosphate (Ca-P) ceramics has set an enduring paradigm of conferring biological regenerative activity to materials with carefully designed structural characteristics. The unique phase composition and porous structural features of osteoinductive Ca-P ceramics allow it to interact with signaling molecules and extracellular matrices in the host system, creating a local environment conducive to new bone formation. Mounting evidence now indicate that the osteoinductive activity of Ca-P ceramics is linked to their physicochemical and three-dimensional structural properties. Inspired by this conceptual breakthrough, many laboratories have shown that other materials can be also enticed to join the rank of tissue-inducing biomaterials, and besides the bones, other tissues such as cartilage, nerves and blood vessels were also regenerated with the assistance of biomaterials. Here, we give a brief historical recount about the discovery of the osteoinductivity of Ca-P ceramics, summarize the underlying material factors and biological characteristics, and discuss the mechanism of osteoinduction concerning protein adsorption, and the interaction with different types of cells, and the involvement of the vascular and immune systems.

The number of people using on-line social networks as a new way of communication is continually increasing. The messages that a user writes in these networks and his/her interactions with other users leave a digital trace that is recorded. Thanks to this fact and the use of network theory, the analysis of messages, user interactions, and the complex structures that emerge is greatly facilitated. In addition, information generated in on-line social networks is labeled temporarily, which makes it possible to go a step further analyzing the dynamics of the interaction patterns. In this article, we present an analysis of the evolution of user interactions that take place in television, socio-political, conference, and keynote events on Twitter. Interactions have been modeled as networks that are annotated with the time markers. We study changes in the structural properties at both the network level and the node level. As a result of this analysis, we have detected patterns of network evolution and common structural features as well as differences among the events. PMID:25961305

Determine the effectiveness of a structured systems-oriented morbidity and mortality conference in improving the process of reviewing and responding to adverse events in a PICU. Prospective time series analysis before and after implementation of a systems-oriented morbidity and mortality conference. Single tertiary referral PICU in Baltimore, MD. Thirty-three patients discussed before and 31 patients after implementation of a systems-oriented morbidity and mortality conference over a total of 20 morbidity and mortality conferences, from April 2013 to March 2014. Systems-oriented morbidity and mortality conference incorporating elements of medical incident analysis. There was a significant increase in meeting attendance (mean, 12 vs 31 attendees per morbidity and mortality conference; p < 0.001) after the systems-oriented morbidity and mortality conference was instituted. There was no significant difference in the mean number of cases suggested (4.2 vs 4.6) or discussed (3.3 vs 3.1) per morbidity and mortality conference. There was also no significant difference in the mean number of adverse events identified per morbidity and mortality conference (3.4 vs 4.3). However, there was an increase in the proportion of cases discussed using a standard case review tool, but this did not reach statistical significance (27% vs 45%; p = 0.231). Nevertheless, we observed a significant increase in the mean number of quality improvement interventions suggested (2.4 vs 5.6; p < 0.001) and implemented (1.7 vs 4.4; p < 0.001) per morbidity and mortality conference. All adverse event categories identified had corresponding interventions suggested after the systems-oriented morbidity and mortality conference was instituted compared with before (80% vs 100%). Intervention-to-adverse event ratios per category were also higher (mean, 0.6 vs 1.5). A structured systems-oriented PICU morbidity and mortality conference incorporating elements of medical incident analysis improves the process of reviewing and responding to adverse events by significantly increasing quality improvement interventions suggested and implemented. Future work would involve testing locally adapted versions of the systems-oriented morbidity and mortality conference in multiple inpatient settings.

Mapping the coupled role of structure and materials in mechanics of platelet-matrix composites

Farzanian, Shafee; Shahsavari, Rouzbeh

2018-03-01

Despite significant progresses on understanding and mimicking the delicate nano/microstructure of biomaterials such as nacre, decoding the indistinguishable merger of materials and structures in controlling the tradeoff in mechanical properties has been long an engineering pursuit. Herein, we focus on an archetype platelet-matrix composite and perform ∼400 nonlinear finite element simulations to decode the complex interplay between various structural features and material characteristics in conferring the balance of mechanical properties. We study various combinatorial models expressed by four key dimensionless parameters, i.e. characteristic platelet length, matrix plasticity, platelet dissimilarity, and overlap offset, whose effects are all condensed in a new unifying parameter, defined as the multiplication of strength, toughness, and stiffness over composite volume. This parameter, which maximizes at a critical characteristic length, controls the transition from intrinsic toughening (matrix plasticity driven without crack growths) to extrinsic toughening phenomena involving progressive crack propagations. This finding, combined with various abstract volumetric and radar plots, will not only shed light on decoupling the complex role of structure and materials on mechanical performance and their trends, but provides important guidelines for designing lightweight staggered platelet-matrix composites while ensuring the best (balance) of their mechanical properties.

Network video conferencing is advancing rapidly throughout the nation, and the Idaho National Engineering Laboratory (INEL), a Department of Energy (DOE) facility, is at the forefront of the development. Engineers at INEL/EG&G designed and installed a very unique DOE videoconferencing system, offering many outstanding features, that include true multipoint conferencing, user-friendly design and operation with no full-time operators required, and the potential for cost effective expansion of the system. One area where INEL/EG&G engineers made a significant contribution to video conferencing was in the development of effective, user-friendly, end station driven scheduling software. A PC at each user site is used to schedule conferences via a windows package. This software interface provides information to the users concerning conference availability, scheduling, initiation, and termination. The menus are 'mouse' controlled. Once a conference is scheduled, a workstation at the hubs monitors the network to initiate all scheduled conferences. No active operator participation is required once a user schedules a conference through the local PC; the workstation automatically initiates and terminates the conference as scheduled. As each conference is scheduled, hard copy notification is also printed at each participating site. Video conferencing is the wave of the future. The use of these user-friendly systems will save millions in lost productivity and travel cost throughout the nation. The ease of operation and conference scheduling will play a key role on the extent industry uses this new technology. The INEL/EG&G has developed a prototype scheduling system for both commercial and federal government use.

When will I see you again? The fate of research findings from international wound care conferences*.

Medical conferences provide a forum for the rapid dissemination of research directly to health professionals and academics. However, the published record of poster and oral presentations from these meetings is usually limited to abstracts. We aimed to assess how many wound studies presented as conference abstracts were eventually published in journals and to identify the factors that predicted publication. The study was a retrospective review. We identified abstracts relating to oral and poster presentation from two large wound conferences. Following data extraction from the abstracts, a systematic search was conducted to examine if the research was subsequently published as a journal article. A time-to-event analysis was conducted to assess predictive associations between features of the research reported in the conference abstracts and time to full publication. In total, 492 abstracts from two European wound care conferences were identified (467 after exclusions). Of the abstracts included, 60% (279) were for posters and 40% (188) were for oral presentations. Over half of the abstracts (53%) reported results from case studies or case series design. In total, only 57 (12%) of the abstracts included resulted in a related publication. Analysis suggested that those studies reporting positive findings were significantly more likely to be published (hazard ratio 1.79, P= 0.001, 95% CIs 1.26-2.55). Few studies presented as conference abstracts at these two wounds conferences were subsequently published. This may be because of the low methodological quality of studies accepted for poster or oral presentation.

Network video conferencing is advancing rapidly throughout the nation, and the Idaho National Engineering Laboratory (INEL), a Department of Energy (DOE) facility, is at the forefront of the development. Engineers at INEL/EG&G designed and installed a very unique DOE video conferencing system, offering many outstanding features, that include true multipoint conferencing, user-friendly design and operation with no full-time operators required, and the potential for cost effective expansion of the system. One area where INEL/EG&G engineers made a significant contribution to video conferencing was in the development of effective, user-friendly, end station driven scheduling software. A PC at each user site is used to schedule conferences via a windows package. This software interface provides information to the users concerning conference availability, scheduling, initiation, and termination. The menus are 'mouse' controlled. Once a conference is scheduled, a workstation at the hub monitors the network to initiate all scheduled conferences. No active operator participation is required once a user schedules a conference through the local PC; the workstation automatically initiates and terminates the conference as scheduled. As each conference is scheduled, hard copy notification is also printed at each participating site. Video conferencing is the wave of the future. The use of these user-friendly systems will save millions in lost productivity and travel costs throughout the nation. The ease of operation and conference scheduling will play a key role on the extent industry uses this new technology. The INEL/EG&G has developed a prototype scheduling system for both commercial and federal government use.

6th International Conference on Nanomaterials by Severe Plastic Deformation (NanoSPD6)

NASA Astrophysics Data System (ADS)

2014-08-01

''NanoSPD'' means Nano-material by Severe Plastic Deformation (SPD), which is an efficient way to obtain bulk nano-structured materials. During SPD, the microstructure of the material is transformed into a very fine structure consisting of ultra fine grains (UFG) approaching even the nano-scale. SPD is different from classical large strain forming processes in two aspects: 1. The sample undergoes extremely large strains without significant change in its dimensions, 2. In most SPD processes high hydrostatic stress is applied which makes it possible to deform difficult-to-form materials. This conference is part of a series of conferences taking place every third year; the history of NanoSPD conferences began in 1999 in Moscow (Russia), followed by Vienna in 2002 (Austria), Fukuoka in 2005 (Japan), Goslar in 2008 (Germany), Nanjing in 2011 (China), and Metz in 2014 (France).

A saponin-detoxifying enzyme mediates suppression of plant defences

NASA Astrophysics Data System (ADS)

Bouarab, K.; Melton, R.; Peart, J.; Baulcombe, D.; Osbourn, A.

2002-08-01

Plant disease resistance can be conferred by constitutive features such as structural barriers or preformed antimicrobial secondary metabolites. Additional defence mechanisms are activated in response to pathogen attack and include localized cell death (the hypersensitive response). Pathogens use different strategies to counter constitutive and induced plant defences, including degradation of preformed antimicrobial compounds and the production of molecules that suppress induced plant defences. Here we present evidence for a two-component process in which a fungal pathogen subverts the preformed antimicrobial compounds of its host and uses them to interfere with induced defence responses. Antimicrobial saponins are first hydrolysed by a fungal saponin-detoxifying enzyme. The degradation product of this hydrolysis then suppresses induced defence responses by interfering with fundamental signal transduction processes leading to disease resistance.

Conference logo On behalf of the organizing committee we welcome all participants to the 16th International Conference on Electron Dynamics In Semiconductors, Optoelectronics and Nanostructures (EDISON). Since the first meeting, organized in 1973 in Modena (Italy), this international conference has been regularly organized mostly each two years, and after 28 years EDISON is back to Montpellier for its 16th edition. This conference was previously known as 'Hot Carriers In Semiconductors' (HCIS). For some years the name was changed into 'Nonequilibrium Carrier Dynamics in Semiconductors' (keeping the acronym HCIS). Then, during the last meeting of the international advisory committee in Tokyo, the decision was taken to find a new denomination that should be more adapted to the latest evolutions in the domains covered by the conference. After several discussions and a vote within the committee, the new acronym of EDISON was chosen. Therefore EDISON 16 can be considered as the last of a long series of conferences and, at the same time, the first of a new cycle of conferences. The primary focus of EDISON is to provide an international meeting place to discuss the latest progress in the field of nonequilibrium classical and quantum carrier dynamics, from semiconductor bulk materials up to advanced structures and nanometric devices. This includes: classical incoherent transport, as well as coherent transport, usually analyzed by means of ultrafast electrical and optical excitations. To accompany the newest developments, TeraHertz phenomena, with a special attention to quantum cascade lasers, have been added to the list of topics. More recently new subjects have been included such as spintronics, transport in organic materials, graphene and carbon nanotubes. This list of topics is regularly modified and updated at each edition of the conference to represent but also anticipate the latest scientific evolutions. The distinctive features of EDISON are: A long-lasting history of 36 years. A fruitful interplay between fundamental and applied science due to a balanced participation of physicists and engineers. Emphasis is put on the physics of future devices rather than on the optimization of existing devices. A balance between theoretical and experimental contributions characterizes the scientific program. The scientific and advisory committees are composed by well-recognized scientists. This year the scientific program was composed by more than 200 contributions divided into 60 oral presentations and 2 poster sessions. To keep a high scientific level, two independent referees have reviewed all submitted abstracts. We are happy to have drawn attendance from more than 30 different countries. We hope that EDISON 16 has been an excellent opportunity for you to meet with colleagues from all over the world in an informal atmosphere, create an opportunity for networking, sharing of scientific and technical information and the building of trust relationships internationally.

We were granted NASA support for partial sponsorship of an international conference on Galactic science, held June 15-17, 2003 and hosted by the Institute for Astrophysical Research at Boston University. This conference, entitled 'Milky Way Surveys: The Structure and Evolution of Our Galaxy' drew some 125 scientific experts, researchers, and graduate students to Boston to: (1) Present large area survey plans and findings; (2) Discuss important remaining questions and puzzles in Galactic science; and (3) To inform and excite students and researchers about the potential for using large area survey databases to address key Galactic science questions. An international Scientific Organizing Committee for this conference crafted a tightly packed two-day conference designed to highlight many recent and upcoming large area surveys (including 2MASS, SDSS, MSX, VLA-HI, GRS, and SIRTF/GLIMPSE) and current theoretical understandings and questions. By bringing together experts in the conduct of Galactic surveys and leading theorists, new ways of attacking long-standing scientific questions were encouraged. The titles of most of the talks and posters presented are attached to the end of this report.

This document contains reproductions of technical papers on some of the most recent research results on aircraft loads, flutter, and structures from the NACA laboratories. These papers were presented by members of the staff of the NACA laboratories at the Conference held at the Langley Aeronautical Laboratory March 5, 6, and 7, 1957. The primary purpose of this Conference was to convey to contractors of the military services and others concerned with the design of aircraft these recent research results and to provide those attending an opportunity to discuss the results. The papers in this document are in the same form in which they were presented at the Conference in order to facilitate their prompt distribution. The original presentation and this record are considered as complementary to, rather than as substitutes for, the Committee?s more complete and formal reports. Accordingly, if information from this document is utilized it is requested that this document not be listed as a reference. Individual reports dealing with most of the information presented at the Conference will subsequently be published by NACA and will therefore be suitable as reference material.

Neuroscience is a rapidly developing area of science which has benefitted from the blurring of interdisciplinary boundaries. This was apparent in the range of papers presented at this year's Neuroscience Ireland Conference, held in Galway during August 2008. The event was attended by academics, postdoctoral and postgraduate researchers, scientists from industry and clinicians. The themes of this year's conference, neurodegeneration, neuroregeneration, pain, glial cell biology and psychopharmacology, were chosen for their reflection of areas of strength in neuroscience within Ireland. In addition to basic science, translational research also featured strongly.

Freer, Martin

2008-05-01

The Cluster Conference is a long-running conference series dating back to the 1960's, the first being initiated by Wildermuth in Bochum, Germany, in 1969. The most recent meeting was held in Nara, Japan, in 2003, and in 2007 the 9th Cluster Conference was held in Stratford-upon-Avon, UK. As the name suggests the town of Stratford lies upon the River Avon, and shortly before the conference, due to unprecedented rainfall in the area (approximately 10 cm within half a day), lay in the River Avon! Stratford is the birthplace of the `Bard of Avon' William Shakespeare, and this formed an intriguing conference backdrop. The meeting was attended by some 90 delegates and the programme contained 65 70 oral presentations, and was opened by a historical perspective presented by Professor Brink (Oxford) and closed by Professor Horiuchi (RCNP) with an overview of the conference and future perspectives. In between, the conference covered aspects of clustering in exotic nuclei (both neutron and proton-rich), molecular structures in which valence neutrons are exchanged between cluster cores, condensates in nuclei, neutron-clusters, superheavy nuclei, clusters in nuclear astrophysical processes and exotic cluster decays such as 2p and ternary cluster decay. The field of nuclear clustering has become strongly influenced by the physics of radioactive beam facilities (reflected in the programme), and by the excitement that clustering may have an important impact on the structure of nuclei at the neutron drip-line. It was clear that since Nara the field had progressed substantially and that new themes had emerged and others had crystallized. Two particular topics resonated strongly condensates and nuclear molecules. These topics are thus likely to be central in the next cluster conference which will be held in 2011 in the Hungarian city of Debrechen. Martin Freer Participants and Cluster'07

Conservation and divergence of C-terminal domain structure in the retinoblastoma protein family

DOE Office of Scientific and Technical Information (OSTI.GOV)

Liban, Tyler J.; Medina, Edgar M.; Tripathi, Sarvind

The retinoblastoma protein (Rb) and the homologous pocket proteins p107 and p130 negatively regulate cell proliferation by binding and inhibiting members of the E2F transcription factor family. The structural features that distinguish Rb from other pocket proteins have been unclear but are critical for understanding their functional diversity and determining why Rb has unique tumor suppressor activities. We describe here important differences in how the Rb and p107 C-terminal domains (CTDs) associate with the coiled-coil and marked-box domains (CMs) of E2Fs. We find that although CTD–CM binding is conserved across protein families, Rb and p107 CTDs show clear preferences formore » different E2Fs. A crystal structure of the p107 CTD bound to E2F5 and its dimer partner DP1 reveals the molecular basis for pocket protein–E2F binding specificity and how cyclin-dependent kinases differentially regulate pocket proteins through CTD phosphorylation. Our structural and biochemical data together with phylogenetic analyses of Rb and E2F proteins support the conclusion that Rb evolved specific structural motifs that confer its unique capacity to bind with high affinity those E2Fs that are the most potent activators of the cell cycle.« less

Breaking optical diffraction limit is one of the most important issues needed to be overcome for the demand of high-density optoelectronic components. Here, a multilayered structure which consists of alternating semiconductor and dielectric layers for breaking optical diffraction limitation at THz frequency region are proposed and analyzed. We numerically demonstrate that such multilayered structure not only can act as a hyperbolic metamaterial but also a birefringence material via the control of the external temperature (or magnetic field). A practical approach is provided to control all the diffraction signals toward a specific direction by using transfer matrix method and effective medium theory. Numerical calculations and computer simulation (based on finite element method, FEM) are carried out, which agree well with each other. The temperature (or magnetic field) parameter can be tuned to create an effective material with nearly flat isofrequency feature to transfer (project) all the k-space signals excited from the object to be resolved to the image plane. Furthermore, this multilayered structure can resolve subwavelength structures at various incident THz light sources simultaneously. In addition, the resolution power for a fixed operating frequency also can be tuned by only changing the magnitude of external magnetic field. Such a device provides a practical route for multi-functional material, photolithography and real-time super-resolution image.

A Food Systems and Public Health conference was convened in April 2009 to consider research supporting food systems that are healthy, green, fair, and affordable. We used a complex systems framework to examine the contents of background material provided to conference participants. Application of our intervention-level framework (paradigm, goals, system structure, feedback and delays, structural elements) enabled comparison of the conference themes of healthy, green, fair, and affordable. At the level of system structure suggested actions to achieve these goals are fairly compatible, including broad public discussion and implementation of policies and programs that support sustainable food production and distribution. At the level of paradigm and goals, the challenge of making healthy and green food affordable becomes apparent as some actions may be in conflict. Systems thinking can provide insight into the challenges and opportunities to act to make the food supply more healthy, green, fair, and affordable. PMID:23173029

Neurorehabilitation protocols based on the use of robotic devices provide a highly repeatable therapy and have recently shown promising clinical results. Little is known about how rehabilitation molds the brain to promote motor recovery of the affected limb. We used a custom-made robotic platform that provides quantitative assessment of forelimb function in a retraction test. Complementary imaging techniques allowed us to access to the multiple facets of robotic rehabilitation-induced cortical plasticity after unilateral photothrombotic stroke in mice Primary Motor Cortex (Caudal Forelimb Area - CFA). First, we analyzed structural features of vasculature and dendritic reshaping in the peri-infarct area with two-photon fluorescence microscopy. Longitudinal analysis of dendritic branches and spines of pyramidal neurons suggests that robotic rehabilitation promotes the stabilization of peri-infarct cortical excitatory circuits, which is not accompanied by consistent vascular reorganization towards pre-stroke conditions. To investigate if this structural stabilization was linked to functional remapping, we performed mesoscale wide-field imaging on GCaMP6 mice while performing the motor task on the robotic platform. We revealed temporal and spatial features of the motor-triggered cortical activation, shining new light on rehabilitation-induced functional remapping of the ipsilesional cortex. Finally, by using an all-optical approach that combines optogenetic activation of the contralesional hemisphere and wide-field functional imaging of peri-infarct area, we dissected the effect of robotic rehabilitation on inter-hemispheric cortico-cortical connectivity.

Not “Pulling up the Ladder”: Women Who Organize Conference Symposia Provide Greater Opportunities for Women to Speak at Conservation Conferences

Sardelis, Stephanie; Drew, Joshua A.

2016-01-01

The scientific community faces numerous challenges in achieving gender equality among its participants. One method of highlighting the contributions made by female scientists is through their selection as featured speakers in symposia held at the conferences of professional societies. Because they are specially invited, symposia speakers obtain a prestigious platform from which to display their scientific research, which can elevate the recognition of female scientists. We investigated the number of female symposium speakers in two professional societies (the Society of Conservation Biology (SCB) from 1999 to 2015, and the American Society of Ichthyologists and Herpetologists (ASIH) from 2005 to 2015), in relation to the number of female symposium organizers. Overall, we found that 36.4% of symposia organizers and 31.7% of symposia speakers were women at the Society of Conservation Biology conferences, while 19.1% of organizers and 28% of speakers were women at the American Society of Ichthyologists and Herpetologists conferences. For each additional female organizer at the SCB and ASIH conferences, there was an average increase of 95% and 70% female speakers, respectively. As such, we found a significant positive relationship between the number of women organizing a symposium and the number of women speaking in that symposium. We did not, however, find a significant increase in the number of women speakers or organizers per symposium over time at either conference, suggesting a need for revitalized efforts to diversify our scientific societies. To further those ends, we suggest facilitating gender equality in professional societies by removing barriers to participation, including assisting with travel, making conferences child-friendly, and developing thorough, mandatory Codes of Conduct for all conferences.

One of the most promising areas for future development is the manipulation of the rhizosphere to produce sustainable and efficient agriculture production systems. Using Omics approaches, to define the distinctive features of eDNA systems and structures, will facilitate progress in rhizo-enforcement and biocontrol studies. The relevance of these studies results clear when we consider the plethora of ecological functions in which eDNA is involved. This fraction can be actively extruded by living cells or discharged during cellular lysis and may exert a key role in the stability and variability of the soil bacterial genome, resulting also a source of nitrogen and phosphorus for plants due to the root's capacity to directly uptake short DNA fragments. The adhesive properties of the DNA molecule confer to eDNA the capacity to inhibit or kill pathogenic bacteria by cation limitation induction, and to facilitate formation of biofilm and extracellular traps (ETs), that may protect microorganisms inhabiting biofilm and plant roots against pathogens and allelopathic substances. The ETs are actively extruded by root border cells when they are dispersed in the rhizosphere, conferring to plants the capacity to extend an endogenous pathogen defence system outside the organism. Moreover, eDNA could be involved in rhizoremediation in heavy metal polluted soil acting as a bioflotation reagent.

The Y.E.S. Congress 2009 was the first international conference organized by the Y.E.S. Network, an association of early-career geoscientists who represent professional societies, geoscience companies, geoscience departments, and interested policy makers from across the world, in collaboration with the International Year of Planet Earth (IYPE). The conference, hosted by the China University of Geosciences in Beijing, focused on scientific and career challenges faced by early-career geoscientists, with a particular emphasis on how the Y.E.S. Network can work collaboratively and internationally towards solving these challenges and furthering the IYPE motto of “Earth Sciences for Society”. A key features of the Y.E.S. Congress was the implementation of “virtualized” roundtable symposia which engaged senior and early-career geoscientists via presentations, panel discussions, and working group sessions in which strategies related to scientific challenges (i.e. climate change in the polar regions, natural hazards, natural resource sustainability) and academic and career pathway challenges (i.e. academic-industry linkages, gender parity in the geosciences, geoscience education sustainability, and international licensure issues) were developed. These strategies were then tasked to the Y.E.S. Network for further development and implementation. The virtualization of the roundtable symposia facilitated active discussion between those participants and speakers who were physically located at the conference facilities in Beijing with a wider international audience of virtual participants and speakers. This talk will address the key features of the roundtable virtualization, the successes and challenges faced during the pre-conference set-up as well as during the roundtable sessions, and potential future applications.

This grant supported the Sixth International Conference on Systems Biology (ICSB 2005), held in Boston, Massachusetts from October 19th to 22nd, 2005. The ICSB is the only major, annual, international conference focused exclusively on the important emerging field of systems biology. It draws together scientists with expertise in theoretical, computational and experimental approaches to understanding biological systems at many levels. Previous ICSB meetings have been held in Tokyo (2000), at Caltech (2001), at the Karolinska Institute (2002), at Washington University in St. Louis (2003), and in Heidelberg (2004). These conferences have been increasingly successful at bringing together the growing communitymore » of established and junior researchers with interests in this area. Boston is home to several groups that have shown leadership in the field and was therefore an ideal place to hold this conference . The executive committee for the conference comprised Jim Collins (Biomedical Engineering, Boston University), Marc Kirschner (chair of the new Department of Systems Biology at Harvard Medical School), Eric Lander (director of the Broad Institute of MIT and Harvard), Andrew Murray (director of Harvard’s Bauer Center for Genomics Research) and Peter Sorger (director of MIT’s Computational and Systems Biology Initiative). There are almost as many definitions of systems biology as there are systems biologists. We take a broad view of the field, and we succeeded in one of our major aims in organizing a conference that bridges two types of divide. The first is that between traditional academic disciplines: each of our sessions includes speakers from biology and from one or more physical or quantitative sciences. The second type includes those that separate experimental biologists from their colleagues who work on theory or computation. Here again, each session included representatives from at least two of these three categories; indeed, many of the speakers combined at least two of the categories in their own research activities. We define systems biology as a widening of focus in biology from individual genes or proteins to the complex networks of these molecules that allow cells and organisms to function. In the same way that conscious thought cannot be said to reside in any single neuron in the brain, simpler biological functions such as cell division arise from the interactions among many components in a network or ‘functional module’. For us, systems biology is characterized by the recognition that a higher-order description of biological function, accompanied by quantitative methods of analysis — often borrowed from disciplines such as physics, engineering, computer science or mathematics — can lead to the identification of general principles that underlie the structure, behavior, and evolution of cells and organisms. The heart of the conference were sessions on six topics: intracellular dynamics (featuring measurements on single cells, and their interpretation); biology by design (synthetic biology); intracellular networks (signal transduction and transcriptional regulation); multicellular networks (development and pattern formation); mechanics and scale in cellular behavior (featuring work on cytoskeletal mechanics, and on scaling relationships in biology); and evolution in action (including experimental evolution, of both real and artificial life-forms). Each session had four invited speakers; 23 of the 24 invited speakers attended (see below). We have selected these speakers not only for the interest of their research, but for their skills as communicators, thereby giving us the best chance of bridging the divides mentioned above. We also made a point of including women, younger investigators and people from outside the United States among the speakers. In addition to the invited speakers, we allotted time in the program for at least five contributed talks, which were selected from the poster submissions. Our aim in selecting these contributors showcased work that is “hot off the bench” (or computer) at the time of the conference, and also created additional opportunities for younger investigators to present their work. The main conference was preceded by a day of tutorials, and followed by two days of workshops, on a range of topics in quantitative, computational and systems biology.« less

The attenuated strain of Mycobacterium bovis Bacille Calmette-Guérin (BCG), used worldwide to prevent tuberculosis and leprosy, is also clinically used as an immunotherapeutic agent against superficial bladder cancer. An anti-tumor polysaccharide has been isolated from the boiling water extract of the Tice substrain of BCG and tentatively characterized as consisting primarily of repeating units of 6-linked-glucosyl residues. Mycobacterium tuberculosis and other mycobacterial species produce a glycogen-like alpha-glucan composed of repeating units of 4-linked glucosyl residues substituted at some 6 positions by short oligoglucosyl units that also exhibits an anti-tumor activity. Therefore, the impression prevails that mycobacteria synthesize different types of anti-neoplastic glucans or, alternatively, the BCG substrains are singular in producing a unique type of glucan that may confer to them their immunotherapeutic property. The present study addresses this question through the comparative analysis of alpha-glucans purified from the extracellular materials and boiling water extracts of three vaccine substrains. The polysaccharides were purified, and their structural features were established by mono- and two-dimensional NMR spectroscopy and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry of the enzymatic and chemical degradation products of the purified compounds. The glucans isolated by the two methods from the three substrains of BCG were shown to exhibit identical structural features shared with the glycogen-like alpha-glucan of M. tuberculosis and other mycobacteria. Incidentally, we observed an occasional release of dextrans from Sephadex columns that may explain the reported occurrence of 6-substituted alpha-glucans in mycobacteria.

Structure-based methods to predict mutational resistance to diarylpyrimidine non-nucleoside reverse transcriptase inhibitors.

Resistance to non-nucleoside reverse transcriptase inhibitors (NNRTIs) is a leading cause of HIV treatment failure. Often included in antiviral therapy, NNRTIs are chemically diverse compounds that bind an allosteric pocket of enzyme target reverse transcriptase (RT). Several new NNRTIs incorporate flexibility in order to compensate for lost interactions with amino acid conferring mutations in RT. Unfortunately, even successful inhibitors such as diarylpyrimidine (DAPY) inhibitor rilpivirine are affected by mutations in RT that confer resistance. In order to aid drug design efforts, it would be efficient and cost effective to pre-evaluate NNRTI compounds in development using a structure-based computational approach. As proof of concept, we applied a residue scan and molecular dynamics strategy using RT crystal structures to predict mutations that confer resistance to DAPYs rilpivirine, etravirine, and investigational microbicide dapivirine. Our predictive values, changes in affinity and stability, are correlative with fold-resistance data for several RT mutants. Consistent with previous studies, mutation K101P is predicted to confer high-level resistance to DAPYs. These findings were further validated using structural analysis, molecular dynamics, and an enzymatic reverse transcription assay. Our results confirm that changes in affinity and stability for mutant complexes are predictive parameters of resistance as validated by experimental and clinical data. In future work, we believe that this computational approach may be useful to predict resistance mutations for inhibitors in development. Published by Elsevier Inc.

Coordinating the Structural Rearrangements Associated with Unidirectional Proton Transfer in the Bacteriorhodopsin Photocycle Induced by Deprotonation of the Proton-Release Group: A Time-Resolved Difference FTIR Spectroscopic Study†

PubMed Central

Morgan, Joel E.; Vakkasoglu, Ahmet S.; Lanyi, Janos K.; Gennis, Robert B.; Maeda, Akio

In the photocycle of bacteriorhodopsin at pH 7, proton release from the proton releasing group (PRG) to the extracellular medium occurs during formation of the M intermediate. This proton release is inhibited at acidic pH, below the pKa of the PRG, ∼6 in M, and instead occurs later in the cycle as the initial state is restored from the O intermediate. Here, structural changes related to deprotonation of the PRG have been investigated by time-resolved FTIR spectroscopy at 25°C. The vibrational features at 2100-1790 cm-1, 1730-1685 cm-1, 1661 cm-1, and 1130-1045 cm-1 have greater negative intensity in the pure M-minus-BR spectrum and even in the M-minus-BR spectrum, that is present earlier together with the L-minus-BR spectrum, at pH 7, than in the corresponding M-minus-BR spectra at pH 5 or pH 4. The D212N mutation abolishes the decreases in the intensities of the broad feature between 1730 and 1685 cm-1 and the band at 1661 cm-1. The 1730-1685 cm-1 feature may arise from transition dipole coupling of the backbone carbonyl groups of Glu204, Phe208, Asp212 and Lys216 interacting with Tyr57 and C15-H of the chromophore. The 1661 cm-1 band, which is insensitive to D2O substitution, may arise by interaction of the backbone carbonyl of Asp212 with C15-H. The 2100-1790 cm-1 feature with a trough at 1885 cm-1 could be due to a water cluster. Depletion of these bands upon deprotonation of the PRG is attributable to disruption of a coordinated structure, held in place by interactions of Asp212. Deprotonation of the PRG is accompanied also by disruption of the interaction of the water molecule near Arg82. The liberated Asp212 may stabilize the protonated state of Asp85, and thus confer uni-directionality to the transport. PMID:20232848

The 7th International Conference on Chemical Kinetics (ICCK) was held July 10-14, 2011, at Massachusetts Institute of Technology (MIT), in Cambridge, MA, hosted by Prof. William H. Green of MIT's Chemical Engineering department. This cross-disciplinary meeting highlighted the importance of fundamental understanding of elementary reactions to the full range of chemical investigations. The specific conference focus was on elementary-step kinetics in both the gas phase and in condensed phase. The meeting provided a unique opportunity to discuss how the same reactive species and reaction motifs manifest under very different reaction conditions (e.g. atmospheric, aqueous, combustion, plasma, in nonaqueous solvents, onmore » surfaces.). The conference featured special sessions on new/improved experimental techniques, improved models and data analysis for interpreting complicated kinetics, computational kinetics (especially rate estimates for large kinetic models), and a panel discussion on how the community should document/archive kinetic data. In the past, this conference had been limited to homogeneous gas-phase and liquid-phase systems. This conference included studies of heterogeneous kinetics which provide rate constants for, or insight into, elementary reaction steps. This Grant from DOE BES covered about half of the subsidies we provided to students and postdocs who attended the conference, by charging them reduced-rate registration fees. The complete list of subsidies provided are listed in Table 1 below. This DOE funding was essential to making the conference affordable to graduate students, and indeed the attendance at this conference was higher than at previous conferences in this series. Donations made by companies provided additional subsidies, leveraging the DOE funding. The conference was very effective in educating graduate students and important in fostering scientific interactions, particularly between scientists studying gas phase and liquid phase kinetics, since those two communities do not meet very often (it had been 6 years since the last time this conference had been held). The conference at MIT was so successful that European scientists decided to organize a similar conference (it will be held in Seville, Spain in July 2013). Almost 200 scientists participated, with more than 100 oral presentations and many poster presentations. A complete list of the presentations and their abstracts are given in the attachment. The conference led to many peer-reviewed papers published in several Special Issues of the International Journal of Chemical Kinetics in early 2012.« less

The crystal structure of the Leishmania infantum Silent Information Regulator 2 related protein 1: Implications to protein function and drug design.

The de novo crystal structure of the Leishmania infantum Silent Information Regulator 2 related protein 1 (LiSir2rp1) has been solved at 1.99Å in complex with an acetyl-lysine peptide substrate. The structure is broadly commensurate with Hst2/SIRT2 proteins of yeast and human origin, reproducing many of the structural features common to these sirtuin deacetylases, including the characteristic small zinc-binding domain, and the larger Rossmann-fold domain involved in NAD+-binding interactions. The two domains are linked via a cofactor binding loop ordered in open conformation. The peptide substrate binds to the LiSir2rp1 protein via a cleft formed between the small and large domains, with the acetyl-lysine side chain inserting further into the resultant hydrophobic tunnel. Crystals were obtained only with recombinant LiSir2rp1 possessing an extensive internal deletion of a proteolytically-sensitive region unique to the sirtuins of kinetoplastid origin. Deletion of 51 internal amino acids (P253-E303) from LiSir2rp1 did not appear to alter peptide substrate interactions in deacetylation assays, but was indispensable to obtain crystals. Removal of this potentially flexible region, that otherwise extends from the classical structural elements of the Rossmann-fold, specifically the β8-β9 connector, appears to result in lower accumulation of the protein when expressed from episomal vectors in L. infantum SIR2rp1 single knockout promastigotes. The biological function of the large serine-rich insertion in kinetoplastid/trypanosomatid sirtuins, highlighted as a disordered region with strong potential for post-translational modification, remains unknown but may confer additional cellular functions that are distinct from their human counterparts. These unique molecular features, along with the resolution of the first kinetoplastid sirtuin deacetylase structure, present novel opportunities for drug design against a protein target previously established as essential to parasite survival and proliferation.

The 16th International Congress on Infectious Diseases (ICID) was held in Cape Town this year, marking the return of the conference to Africa for the first time in 22 years. While infectious diseases such as malaria, tuberculosis and HIV--all still prevalent in the African healthcare landscape--dominated the program, the conference featured several important sessions on fungal infection and a significant number of posters devoted to this critical medical area. Within the context of the rise of antimicrobial resistance, now identified by the WHO as one of the three greatest threats to human health, came the message that resistance is not limited to antimicrobials, but that antifungal resistance is also a significant and emerging threat worldwide.

The opioid receptor family comprises three members, the {mu}-, {delta}- and {kappa}-opioid receptors, which respond to classical opioid alkaloids such as morphine and heroin as well as to endogenous peptide ligands like endorphins. They belong to the G-protein-coupled receptor (GPCR) superfamily, and are excellent therapeutic targets for pain control. The {delta}-opioid receptor ({delta}-OR) has a role in analgesia, as well as in other neurological functions that remain poorly understood. The structures of the {mu}-OR and {kappa}-OR have recently been solved. Here we report the crystal structure of the mouse {delta}-OR, bound to the subtype-selective antagonist naltrindole. Together with the structuresmore » of the {mu}-OR and {kappa}-OR, the {delta}-OR structure provides insights into conserved elements of opioid ligand recognition while also revealing structural features associated with ligand-subtype selectivity. The binding pocket of opioid receptors can be divided into two distinct regions. Whereas the lower part of this pocket is highly conserved among opioid receptors, the upper part contains divergent residues that confer subtype selectivity. This provides a structural explanation and validation for the 'message-address' model of opioid receptor pharmacology, in which distinct 'message' (efficacy) and 'address' (selectivity) determinants are contained within a single ligand. Comparison of the address region of the {delta}-OR with other GPCRs reveals that this structural organization may be a more general phenomenon, extending to other GPCR families as well.« less

Amino-acid coevolution can be referred to mutational compensatory patterns preserving the function of a protein. Viral envelope glycoproteins, which mediate entry of enveloped viruses into their host cells, are shaped by coevolution signals that confer to viruses the plasticity to evade neutralizing antibodies without altering viral entry mechanisms. The functions and structures of the two envelope glycoproteins of the Hepatitis C Virus (HCV), E1 and E2, are poorly described. Especially, how these two proteins mediate the HCV fusion process between the viral and the cell membrane remains elusive. Here, as a proof of concept, we aimed to take advantage of an original coevolution method recently developed to shed light on the HCV fusion mechanism. When first applied to the well-characterized Dengue Virus (DENV) envelope glycoproteins, coevolution analysis was able to predict important structural features and rearrangements of these viral protein complexes. When applied to HCV E1E2, computational coevolution analysis predicted that E1 and E2 refold interdependently during fusion through rearrangements of the E2 Back Layer (BL). Consistently, a soluble BL-derived polypeptide inhibited HCV infection of hepatoma cell lines, primary human hepatocytes and humanized liver mice. We showed that this polypeptide specifically inhibited HCV fusogenic rearrangements, hence supporting the critical role of this domain during HCV fusion. By combining coevolution analysis and in vitro assays, we also uncovered functionally-significant coevolving signals between E1 and E2 BL/Stem regions that govern HCV fusion, demonstrating the accuracy of our coevolution predictions. Altogether, our work shed light on important structural features of the HCV fusion mechanism and contributes to advance our functional understanding of this process. This study also provides an important proof of concept that coevolution can be employed to explore viral protein mediated-processes, and can guide the development of innovative translational strategies against challenging human-tropic viruses.

Extracellular matrix structure governs invasion resistance in bacterial biofilms.

PubMed

Nadell, Carey D; Drescher, Knut; Wingreen, Ned S; Bassler, Bonnie L

2015-08-01

Many bacteria are highly adapted for life in communities, or biofilms. A defining feature of biofilms is the production of extracellular matrix that binds cells together. The biofilm matrix provides numerous fitness benefits, including protection from environmental stresses and enhanced nutrient availability. Here we investigate defense against biofilm invasion using the model bacterium Vibrio cholerae. We demonstrate that immotile cells, including those identical to the biofilm resident strain, are completely excluded from entry into resident biofilms. Motile cells can colonize and grow on the biofilm exterior, but are readily removed by shear forces. Protection from invasion into the biofilm interior is mediated by the secreted protein RbmA, which binds mother-daughter cell pairs to each other and to polysaccharide components of the matrix. RbmA, and the invasion protection it confers, strongly localize to the cell lineages that produce it.

A web-based research information system was designed to enable our research team to efficiently measure health related quality of life among frail older adults in a variety of health care settings (home care, nursing homes, assisted living, PACE). The structure, process, and outcome data is collected using laptop computers and downloaded to a SQL database. Unique features of this project are the ability to transfer research to practice by instantly sharing individual and aggregate results with the clinicians caring for these elders and directly impacting the quality of their care. Clinicians can also dial in to the database to access standard queries or receive customized reports about the patients in their facilities. This paper will describe the development and implementation of the information system. The conference presentation will include a demonstration and examples of research to practice benefits.

National conference didactic lectures have traditionally featured hour-long lecture-based presentations. However, there is evidence that longer lectures can lead to both decreased attention and retention of information. The authors sought to identify trends in lecture duration, lecture types, and number of speakers at four national emergency medicine (EM) conferences over a 6-year period. The authors performed a retrospective analysis of the length, number of speakers, and format of didactic lectures at four different national EM conferences over 6 years. The authors abstracted data from the national academic assemblies for the four largest not-for-profit EM organizations in the United States: American Academy of Emergency Medicine, American College of Emergency Physicians, Council of Emergency Medicine Residency Directors, and Society for Academic Emergency Medicine. There was a significant yearly decrease in the mean lecture lengths for three of the four conferences. There was an increase in the percentage of rapid fire sessions over the preceding 2 years with a corresponding decrease in the percentage of general educational sessions. There was no significant difference in the mean number of speakers per lecture. An analysis of 4210 didactic lecture sessions from the annual meetings of four national EM organizations over a 6-year period showed significant decreases in mean lecture length. These findings can help to guide EM continuing medical education conference planning and research.

The 3 rd World Conference on Kisspeptin, "Kisspeptin 2017: Brain and Beyond" was held March 30-31 at the Rosen Centre Hotel in Orlando, Florida, providing an international forum for multidisciplinary scientists to meet and share cutting-edge research on kisspeptin biology and its relevance to human health and disease. The meeting built upon previous world conferences focused on the role of kisspeptin and associated peptides in the control of gonadotropin-releasing hormone (GnRH) secretion and reproduction. Based on recent discoveries, the scope of this meeting was expanded to include functions of kisspeptin and related peptides in other physiological systems including energy homeostasis, pregnancy, ovarian and uterine function, and thermoregulation. In addition, discussions addressed the translation of basic knowledge of kisspeptin biology to the treatment of disease, with the goal of seeking consensus about the best approaches to improve human health. The two-day meeting featured a non-traditional structure, with each day starting with poster sessions followed by lunch discussions and facilitated large-group sessions with short presentations to maximize the exchange of new, unpublished data. Topics were identified by a survey prior to the meeting, and focused on major unresolved questions, important controversies, and future directions in the field. Finally, career development activities provided mentoring for trainees and junior investigators, and networking opportunities for those individuals with established researchers in the field. Overall, the meeting was rated as a success by attendees and covered a wide range of lively and provocative discussion topics on the changing nature of the field of "kisspeptinology" and its future.

Molecular Features Underlying Selectivity in Chicken Bitter Taste Receptors.

PubMed

Di Pizio, Antonella; Shy, Nitzan; Behrens, Maik; Meyerhof, Wolfgang; Niv, Masha Y

2018-01-01

Chickens sense the bitter taste of structurally different molecules with merely three bitter taste receptors ( Gallus gallus taste 2 receptors, ggTas2rs), representing a minimal case of bitter perception. Some bitter compounds like quinine, diphenidol and chlorpheniramine, activate all three ggTas2rs, while others selectively activate one or two of the receptors. We focus on bitter compounds with different selectivity profiles toward the three receptors, to shed light on the molecular recognition complexity in bitter taste. Using homology modeling and induced-fit docking simulations, we investigated the binding modes of ggTas2r agonists. Interestingly, promiscuous compounds are predicted to establish polar interactions with position 6.51 and hydrophobic interactions with positions 3.32 and 5.42 in all ggTas2rs; whereas certain residues are responsible for receptor selectivity. Lys 3.29 and Asn 3.36 are suggested as ggTas2r1-specificity-conferring residues; Gln 6.55 as ggTas2r2-specificity-conferring residue; Ser 5.38 and Gln 7.42 as ggTas2r7-specificity conferring residues. The selectivity profile of quinine analogs, quinidine, epiquinidine and ethylhydrocupreine, was then characterized by combining calcium-imaging experiments and in silico approaches. ggTas2r models were used to virtually screen BitterDB compounds. ~50% of compounds known to be bitter to human are likely to be bitter to chicken, with 25, 20, 37% predicted to be ggTas2r1, ggTas2r2, ggTas2r7 agonists, respectively. Predicted ggTas2rs agonists can be tested with in vitro and in vivo experiments, contributing to our understanding of bitter taste in chicken and, consequently, to the improvement of chicken feed.

Despite the enormous potential in bioinspired fabrication of high-strength structure by mimicking the spinning process of spider silk, currently accessible routes (e.g., microfluidic and electrospinning approaches) still have substantial function gaps in providing precision control over the nanofibrillar superstructure, crystalline morphology or molecular orientation. Here the concept of biomimetic nanofibrillation, by copying the spiders’ spinning principles, was conceived to build silk-mimicking hierarchies in two-phase biodegradable blends, strategically involving the stepwise integration of elongational shear and high-pressure shear. Phase separation confined on nanoscale, together with deformation of discrete phases and pre-alignment of polymer chains, was triggered in the elongational shear, conferring the readiness for direct nanofibrillation in the latter shearing stage. The orderly aligned nanofibrils, featuring an ultralow diameter of around 100 nm and the “rigid-soft” system crosslinked by nanocrystal domains like silk protein dopes, were secreted by fine nanochannels. The incorporation of multiscale silk-mimicking structures afforded exceptional combination of strength, ductility and toughness for the nanofibrillar polymer composites. The proposed spider spinning-mimicking strategy, offering the biomimetic function integration unattainable with current approaches, may prompt materials scientists to pursue biopolymer mimics of silk with high performance yet light weight.

With advances in the development and application of Ames mutagenicity in silico prediction tools, the International Conference on Harmonisation (ICH) has amended its M7 guideline to reflect the use of such prediction models for the detection of mutagenic activity in early drug safety evaluation processes. Since current Ames mutagenicity prediction tools only focus on functional group alerts or side chain modifications of an analog series, these tools are unable to identify mutagenicity derived from core structures or specific scaffolds of a compound. In this study, a large collection of 6512 compounds are used to perform scaffold tree analysis. By relating different scaffolds on constructed scaffold trees with Ames mutagenicity, four major and one minor novel mutagenic groups of scaffold are identified. The recognized mutagenic groups of scaffold can serve as a guide for medicinal chemists to prevent the development of potentially mutagenic therapeutic agents in early drug design or development phases, by modifying the core structures of mutagenic compounds to form non-mutagenic compounds. In addition, five series of substructures are provided as recommendations, for direct modification of potentially mutagenic scaffolds to decrease associated mutagenic activities. PMID:26863515

The ADS Abstract Service contains over 2.3 million references in four databases: Astronomy/Astrophysics/Planetary Sciences, Instrumentation, Physics/Geophysics, and Preprints. We provide abstracts and articles free to the astronomical community for all major and many smaller astronomy journals, PhD theses, conference proceedings, and technical reports. These four databases can be queried either separately of jointly. The ADS also has scanned 1.3 million pages in 180,000 articles in the ADS Article Service. This literature archive contains all major Astronomy journals and many smaller journals, as well as conference proceedings, including the abstract books from all the LPSCs back to volume 2. A new feature gives our users the ability to see list of articles that were also read by the readers of a given article. This is a powerful tool to find out what current articles are relevant in a particular field of study. We have recently expanded the citation and reference query capabilities. It allows our users to select papers for which they want to see references or citations and then retrieve these citations/references. Another new capability is the ability to sort a list of articles by their citation count. As usual, users should be reminded that the citations in ADS are incomplete because we do not obtain reference lists from all publishers. In addition, we cannot match all references (e.g. in press, private communications, author errors, some conference papers, etc.). Anyone using the citations for analysis of publishing records should keep this in mind. More work on expanding the citation and reference features is planned over the next year.

The 2012 Gordon Research Conference on Mitochondria and Chloroplasts will assemble an international group of scientists investigating fundamental properties of these organelles, and their integration into broader physiological processes. The conference will emphasize the many commonalities between mitochondria and chloroplasts: their evolution from bacterial endosymbionts, their genomes and gene expression systems, their energy transducing membranes whose proteins derive from both nuclear and organellar genes, the challenge of maintaining organelle integrity in the presence of the reactive oxygen species that are generated during energy transduction, their incorporation into organismal signaling pathways, and more. The conference will bring together investigators working inmore » animal, plant, fungal and protozoan systems who specialize in cell biology, genetics, biochemistry, physiology, proteomics, genomics, and structural biology. As such, this conference will provide a unique forum that engenders cross-disciplinary discussions concerning the biogenesis, dynamics, and regulation of these key cellular structures. By fostering interactions among mammalian, fungal and plant organellar biologists, this conference also provides a conduit for the transmission of mechanistic insights obtained in model organisms to applications in medicine and agriculture. The 2012 conference will highlight areas that are moving rapidly and emerging themes. These include new insights into the ultrastructure and organization of the energy transducing membranes, the coupling of organellar gene expression with the assembly of photosynthetic and respiratory complexes, the regulatory networks that couple organelle biogenesis with developmental and physiological signals, the signaling events through which organellar physiology influences nuclear gene expression, and the roles of organelles in disease and development.« less

Preface: Proceedings of the 13th Conference on Liquid and Amorphous Metals (LAM13) (Ekaterinburg, Russia, 8 14 July 2007)

NASA Astrophysics Data System (ADS)

Popel, Pjotr; Gelchinskii, Boris; Sidorov, Valeriy

2008-03-01

The most recent developments in the field of liquid and amorphous metals and alloys are regularly updated through two complementary international conferences: the liquid and amorphous metals conference (LAM) and the rapidly quenched materials (RQ) conference. The first series of conferences started as LM1 in 1966 at Brookhaven for the basic understanding of liquid metals. The subsequent LM conferences were held in Tokyo (1972) and Bristol (1976). The conference was renewed in Grenoble (1980) as a LAM conference including amorphous metals and continued in Los Angeles (1983), Garmisch-Partenkirchen (1986), Kyoto (1989), Vienna (1992), Chicago (1995), Dortmund (1998), Yokohama (2001) and Metz (2004). The conferences are mainly devoted to liquid and amorphous metals and alloys. However, communications on some non-metallic systems such as semiconductors, quasicrystals etc, are also accepted. The conference tradition strongly encourages participation from junior researchers and graduate students. The 13th conference of the LAM series was organized in Ekaterinburg, Russia, by the Institute of Metallurgy of the Ural Branch of the Russian Academy of Sciences (IMet UB RAS) and the Ural State Pedagogical University (USPU), and held from 8-14 July 2007 under the chairmanship of Professors Pjotr Popel (USPU) and Boris Gelchinskii (IMet UB RAS). Two hundred and forty two active participants and about 60 guest participants from 20 countries attended the conference. There were no parallel sessions and all oral reports were separated into three groups: invited talks (40 min), full-scale oral reports (25 min), and brief oral reports (15 min). The program included ten sessions, ranging from purely theoretical subjects to the technological application of molten and amorphous alloys. The following sessions took place: A: Electronic structure and transport, magnetic properties; B: Phase transitions; C: Structure; D: Atomic dynamics and transport; E: Thermodynamics; F: Modelling, simulation; G: Surface and interface; H: Mechanical properties and new materials; I: Quasicrystals; J: Industrial applications. The largest sessions were E, C, D and F with 53, 47, 43 and 40 reports, respectively. Posters were exhibited during the first (sessions A-E) or last (sessions F-J) three days of the conference. As usual, each oral session started with an invited talk. In accordance with contemporary tendencies the first invited talk of M Yao (Kyoto University) was devoted to interrelations between liquid metal studies and nanoscience. He pointed out that the physics of disordered matter, especially liquid metals, has provided nanoscience with basic ideas and theoretical tools such as ab initio molecular dynamics (MD) simulation. K Tamura (Kyoto University) reported experimental investigation results of expanded liquid rubidium, showing that observed structural features are originated from the instability of low-density electron gas. Modern theory has predicted that interacting electron gas suffers negative compressibility and the static dielectric function (DF) becomes negative when electron density is sufficiently reduced. Negative DF is of special interest when considering the possibility of new types of superconductors. In the next invited lecture, M I Mendelev and J R Morris (USA) described how MD simulations were performed to study phase transformations in supercooled liquid Al. The authors found that the widely used EAM potential for Al enables vitrification for cooling rates achievable in classical MD simulation, while other Al potentials enable crystallization under the same conditions. The reason for this difference was discussed, as well as features of vitrification in the EA Al. P Häussler (Chemnitz Univeristy) spoke about fundamental structure-forming processes in liquid and amorphous materials. He proposed the resonance model as an autonomous missing link between the microscopic description of atoms/molecules of Schrödinger's equation, and crystals, where global concepts such as planar resonances exist and Bloch's theorem is applied. D Holland-Moritz (Institut für Materialphysik, Köln) presented the first results of the quasielastic neutron scattering experiments on electromagnetically levitated metallic melts. The studies were indicative of Arrhenius behavior of the diffusion constants over the whole temperature regime investigated, ranging from temperatures above the melting temperature up to the metastable regime of an undercooled liquid. L Son (USPU) discussed the existing analytical theories of liquid-liquid phase transitions that have been assumed for a wide variety of liquids, but are poorly understood analytically. The application of these theories to liquid metal systems was also demonstrated. An approach to the study of dynamics and kinetics of cavitation in stretched liquid metals by the classical MD method was presented in the talk of G E Norman (Institute for High Temperatures, Moscow). Both quantitative and qualitative disagreements with the classic theory of homogeneous nucleation were found. Analytic extentions of MD results beyond the space and temporal limits accessible for the MD method were also discussed. G Wilde (University of Muenster) spoke about the experimental investigation into the impact of interface properties and, more specifically, of interface morphology in matrix-encased metallic nanoparticles on macroscopic properties, such as melting transition by a combination of microscopic, microanalytical and calorimetric measurements. The results were discussed with respect to the underlying mechanisms that lead to size dependent phase equilibria. In the invited talk of V Keryvin (University of Rennes) the indentation ability was proposed as a probe for pressure sensitivity in metallic glasses. The main conclusion was that the indentation test provides a good means to study the elasto-plastic behavior of these materials as well as being a relevant tool to subject metallic glasses to multiaxial loadings. The influence of changes in local ordering of precursor melt on the formation of the amorphous state and subsequent crystallization was the subject of a report presented by P Śvec (Institute of Physics, Bratislava). The effect was shown for a rapidly quenched Fe-Mo-B system with addition of Cu and substitution of Fe by Co prepared under varying conditions of planar flow casting and using master alloys with specific melt treatment. Approximately 320 abstracts were received and 180 manuscripts were finally submitted for publication. Papers from invited lectures and full-scale oral reports are published in Journal of Physics: Condensed Matter for this special issue. All papers from brief oral reports and posters were collected for an issue of Journal of Physics: Conference Series. All were edited by staff from Ekaterinburg. It was decided during the joint meeting of both the International Advisory Board and International Program Committee that the next conference in the LAM series, LAM14, will be arranged by the groups of A Di Cicco (Camerino University) and T Scopigno (University of Rome 'La Sapienza'), and will take place in Rome, Italy, in 2010. It is no easy task to outline new scientific tendencies in the field of liquid and amorphous alloys just after the LAM conference. It takes one or two years to estimate the significance of the event. Only one conclusion is obvious: the LAM13 conference has opened a door between the global scientific community and Russian scientists, who have special expertise in the field but could not actively participate at the LAM conferences before because of the economic situation in Russia. We are grateful to the Advisory and Program Committees of the LAM12 conference in Metz and especially to Dr Monique Calvo-Dahlborg for the opportunity to manage such an event in Russia. In addition we would like to give our sincere thanks to: the authorities of the Ural Branch of the Russian Academy of Sciences and the Ural State Pedagogical University who did their best to help us with all our problems, especially to Boris Igoshev and Nikolay Vatolin; all the sponsors who supported the conference: the Russian Foundation for Basic Research, the Ural Mining and Metallurgical Company headed by Andrey Kozicyn, the Open Joint Stock Company 'Uralsvjazinform' (Alexey Ufimkin), the A A Baikov Institute of Metallurgy and Materials Science, RAS (July Kovneristii), the Institute for Physics and Power Engineering (Alexandre Ephanov), the Nuclear Power Plant 'Beloyarskaya' (Nikolay Oshkanov), the South Ural State University (German Vjatkin), Ural Technical Institute of Communications and Informatics (Evgeny Subbotin), Physical-Technical Institute UB RAS (Vladimir Lad'yanov), Metallurgical Department of the Ural State Technical University (Victor Shimov), Academy of Sciences of Chechen Republic (Raikom Dadashev) and NETZSCH-Gerätebau GmbH; the invited lecturers who immediately answered positively to the invitation and contributed to the high level of success of LAM13; the colleagues who acted as chairmen in the various sessions; Graham Douglas and Richard Palmer who kindly answered our queries and tried to satisfy our requirements; the seniors of the LAM series who could not participate at the 13th conference but helped us to manage it in the best way, namely J Dupuy, M Silbert, F Sommer, W C Pilgrim, W Freyland, K Lu, J Brmejo and F Hensel. We dedicate the LAM13 conference to the 80 year jubilee of Professor Nikolay Vatolin who is one of the leaders of Russian investigation in the field of liquid and amorphous metals, and who managed 12 similar conferences in our country. One of us (PP) commemorates his father, Professor Stanislav Popel, who was a known specialist in high temperature capillarity and sadly left us six months before the event.

Two-photon imaging combined with targeted fluorescent indicators is extensively used for visualizing critical features of brain functionality and structural plasticity. Back-scattered photons from the NIR laser provide complimentary information without introducing any exogenous labelling. Here, we describe a versatile approach that, by collecting the reflected NIR light, provides structural details on the myelinated axons and blood vessels in the brain, both in fixed samples and in live animals. Indeed, by combining NIR reflectance and two-photon imaging of a slice of hippocampus from Thy1-GFPm mice, we show the presence of randomly oriented axons intermingled with sparsely fluorescent neuronal processes. The back-scattered photons guide the contextualization of the fluorescence structure within brain atlas thanks to the recognition of characteristic hippocampal structures. Label-free detection of axonal elongations over the layer 2/3 of mouse cortex under a cranial window was also possible in live brain. Finally, blood flow could be measured in vivo, thus validating label free NIR reflectance as a tool for monitoring hemodynamic fluctuations. The prospective versatility of this label-free technique complimentary to two-photon fluorescence microscopy is demonstrated in a mouse model of photothrombotic stroke in which the axonal degeneration and blood flow remodeling can be investigated simultaneously.

This study examines the correlation between the radiologist-defined severity of normal tissue damage following radiation therapy (RT) for lung cancer treatment and a set of mathematical descriptors of computed tomography (CT) scan texture (‘texture features’). A pre-therapy CT scan and a post-therapy CT scan were retrospectively collected under IRB approval for each of the 25 patients who underwent definitive RT (median dose: 66 Gy). Sixty regions of interest (ROIs) were automatically identified in the non-cancerous lung tissue of each post-therapy scan. A radiologist compared post-therapy scan ROIs with pre-therapy scans and categorized each as containing no abnormality, mild abnormality, moderate abnormality, or severe abnormality. Twenty texture features that characterize gray-level intensity, region morphology, and gray-level distribution were calculated in post-therapy scan ROIs and compared with anatomically matched ROIs in the pre-therapy scan. Linear regression and receiver operating characteristic (ROC) analysis were used to compare the percent feature value change (ΔFV) between ROIs at each category of visible radiation damage. Most ROIs contained no (65%) or mild abnormality (30%). ROIs with moderate (3%) or severe (2%) abnormalities were observed in 9 patients. For 19 of 20 features, ΔFV was significantly different among severity levels. For 12 features, significant differences were observed at every level. Compared with regions with no abnormalities, ΔFV for these 12 features increased, on average, by 1.5%, 12%, and 30%, respectively, for mild, moderate, and severe abnormalitites. Area under the ROC curve was largest when comparing ΔFV in the highest severity level with the remaining three categories (mean AUC across features: 0.84). In conclusion, 19 features that characterized the severity of radiologic changes from pre-therapy scans were identified. These features may be used in future studies to quantify acute normal lung tissue damage following RT. Presented, in part at the IASLC 15th World Conference on Lung Conference, Sydney, AUS (2013).

This study describes the results of a multidisciplinary conference (the Baltimore Conference) that met to develop consensus guidelines for competency specification and measurement in postdoctoral training in rehabilitation psychology. Forty-six conference participants were chosen to include representatives of rehabilitation psychology training and practice communities, representatives of psychology accreditation and certification bodies, persons involved in medical education practice and research, and consumers of training programs (students). Consensus education and training guidelines were developed that specify the key competencies in rehabilitation psychology postdoctoral training, and structured observation checklists were developed for their measurement. This study continues the development of more than 50 years of thinking about education and training in rehabilitation psychology and builds on the existing work to further advance the development of guidelines in this area. The conference developed aspirational guidelines for competency specification and measurement in rehabilitation psychology postdoctoral training (i.e., for studying the outcomes of these training programs). Structured observation of trainee competencies allows examination of actual training outcomes in relation to intended outcomes and provides a methodology for studying how program outcomes are related to program structures and processes so that program improvement can occur. Best practices in applying program evaluation research methods to the study of professional training programs are discussed. (c) 2015 APA, all rights reserved).

HIV-1 protease inhibitors are part of the highly active antiretroviral therapy effectively used in the treatment of HIV infection and AIDS. Darunavir (DRV) is the most potent of these inhibitors, soliciting drug resistance only when a complex combination of mutations occur both inside and outside the protease active site. With few exceptions, the role of mutations outside the active site in conferring resistance remains largely elusive. Through a series of DRV-protease complex crystal structures, inhibition assays, and molecular dynamics simulations, we find that single and double site mutations outside the active site often associated with DRV resistance alter the structure and dynamic ensemble of HIV-1 protease active site. These alterations correlate with the observed inhibitor binding affinities for the mutants, and suggest a network hypothesis on how the effect of distal mutations are propagated to pivotal residues at the active site and may contribute to conferring drug resistance.

Prototypes for Content-Based Image Retrieval in Clinical Practice

2011-01-01

Content-based image retrieval (CBIR) has been proposed as key technology for computer-aided diagnostics (CAD). This paper reviews the state of the art and future challenges in CBIR for CAD applied to clinical practice. We define applicability to clinical practice by having recently demonstrated the CBIR system on one of the CAD demonstration workshops held at international conferences, such as SPIE Medical Imaging, CARS, SIIM, RSNA, and IEEE ISBI. From 2009 to 2011, the programs of CADdemo@CARS and the CAD Demonstration Workshop at SPIE Medical Imaging were sought for the key word “retrieval” in the title. The systems identified were analyzed and compared according to the hierarchy of gaps for CBIR systems. In total, 70 software demonstrations were analyzed. 5 systems were identified meeting the criterions. The fields of application are (i) bone age assessment, (ii) bone fractures, (iii) interstitial lung diseases, and (iv) mammography. Bridging the particular gaps of semantics, feature extraction, feature structure, and evaluation have been addressed most frequently. In specific application domains, CBIR technology is available for clinical practice. While system development has mainly focused on bridging content and feature gaps, performance and usability have become increasingly important. The evaluation must be based on a larger set of reference data, and workflow integration must be achieved before CBIR-CAD is really established in clinical practice. PMID:21892374

Genetics of hybrid male sterility among strains and species in the Drosophila pseudoobscura species group

PubMed Central

McDermott, Shannon R.; Noor, Mohamed A. F.

2011-01-01

Taxa in the early stages of speciation may bear intraspecific allelic variation at loci conferring barrier traits in hybrids such as hybrid sterility. Additionally, hybridization may spread alleles that confer barrier traits to other taxa. Historically, few studies examine within- and between-species variation at loci conferring reproductive isolation. Here, we test for allelic variation within Drosophila persimilis and within the Bogota subspecies of D. pseudoobscura at regions previously shown to contribute to hybrid male sterility. We also test whether D. persimilis and the USA subspecies of D. pseudoobscura share an allele conferring hybrid sterility in a D. pseudoobscura bogotana genetic background. All loci conferred similar hybrid sterility effects across all strains studied, though we detected some statistically significant quantitative effect variation among D. persimilis alleles of some hybrid incompatibility QTLs. We also detected allelism between D. persimilis and D. pseudoobscura USA at a 2nd chromosome hybrid sterility QTL. We hypothesize that either the QTL is ancestral in D. persimilis and D. pseudoobscura USA and lost in D. pseudoobscura bogotana, or gene flow transferred the QTL from D. persimilis to D. pseudoobscura USA. We discuss our findings in the context of population features that may contribute to variation in hybrid incompatibilities. PMID:21729052

The International Society of Urological Pathology (ISUP) held an expert-driven penile cancer conference in Boston in March 2015, which focused on the new World Health Organisation (WHO) classification of penile cancer: human papillomavirus (HPV)-related tumours and histological grading. The conference was preceded by an online survey of the ISUP members, and the results were used to initiate discussions. Because of the rarity of penile tumours, this was not a consensus but an expert-driven conference aimed at assisting pathologists who do not see these tumours on a regular basis. After a justification for the novel separation of penile squamous cell carcinomas into HPV-related and non-HPV-related-carcinomas, the histological classification of penile carcinoma was proposed; this system was also accepted subsequently by the WHO for subtyping of penile carcinomas (2016). A description of HPV-related neoplasms, which may be recognised by their histological features, was presented, and p16 was recommended as a surrogate indicator of HPV. A three-tier grading system was recommended for penile squamous carcinomas; this was also adopted by the WHO (2016). Many of the distinctive histological subtypes of squamous cell carcinoma of the penis are associated with distinct grades, based on the squamous cell carcinoma subtype histological features. © 2017 John Wiley & Sons Ltd.

A novel algorithm for delineating wetland depressions and ...

EPA Pesticide Factsheets

In traditional watershed delineation and topographic modeling, surface depressions are generally treated as spurious features and simply removed from a digital elevation model (DEM) to enforce flow continuity of water across the topographic surface to the watershed outlets. In reality, however, many depressions in the DEM are actual wetland landscape features that are seldom fully filled with water. For instance, wetland depressions in the Prairie Pothole Region (PPR) are seasonally to permanently flooded wetlands characterized by nested hierarchical structures with dynamic filling- spilling-merging surface-water hydrological processes. The objectives of this study were to delineate hierarchical wetland catchments and model their hydrologic connectivity using high-resolution LiDAR data and aerial imagery. We proposed a novel algorithm delineate the hierarchical wetland catchments and characterize their geometric and topological properties. Potential hydrologic connectivity between wetlands and streams were simulated using the least-cost path algorithm. The resulting flow network delineated putative temporary or seasonal flow paths connecting wetland depressions to each other or to the river network at scales finer than available through the National Hydrography Dataset. The results demonstrated that our proposed framework is promising for improving overland flow modeling and hydrologic connectivity analysis. Presentation at AWRA Spring Specialty Conference in Sn

Anisotropy of the Seebeck Coefficient in the Cuprate Superconductor YBa2 Cu3 Oy : Fermi-Surface Reconstruction by Bidirectional Charge Order

The Seebeck coefficient S of the cuprate YBa2 Cu3 Oy is measured in magnetic fields large enough to suppress superconductivity, at hole dopings p =0.11 and p =0.12 , for heat currents along the a and b directions of the orthorhombic crystal structure. For both directions, S /T decreases and becomes negative at low temperature, a signature that the Fermi surface undergoes a reconstruction due to broken translational symmetry. Above a clear threshold field, a strong new feature appears in Sb, for conduction along the b axis only. We attribute this feature to the onset of 3D-coherent unidirectional charge-density-wave modulations seen by x-ray diffraction, also along the b axis only. Because these modulations have a sharp onset temperature well below the temperature where S /T starts to drop towards negative values, we infer that they are not the cause of Fermi-surface reconstruction. Instead, the reconstruction must be caused by the quasi-2D bidirectional modulations that develop at significantly higher temperature. The unidirectional order only confers an additional anisotropy to the already reconstructed Fermi surface, also manifest as an in-plane anisotropy of the resistivity.

Responses of auditory-cortex neurons to structural features of natural sounds.

1999-01-14

Sound-processing strategies that use the highly non-random structure of natural sounds may confer evolutionary advantage to many species. Auditory processing of natural sounds has been studied almost exclusively in the context of species-specific vocalizations, although these form only a small part of the acoustic biotope. To study the relationships between properties of natural soundscapes and neuronal processing mechanisms in the auditory system, we analysed sound from a range of different environments. Here we show that for many non-animal sounds and background mixtures of animal sounds, energy in different frequency bands is coherently modulated. Co-modulation of different frequency bands in background noise facilitates the detection of tones in noise by humans, a phenomenon known as co-modulation masking release (CMR). We show that co-modulation also improves the ability of auditory-cortex neurons to detect tones in noise, and we propose that this property of auditory neurons may underlie behavioural CMR. This correspondence may represent an adaptation of the auditory system for the use of an attribute of natural sounds to facilitate real-world processing tasks.

Discovering the intelligence in molecular biology.

Uberbacher, E

1995-12-01

The Third International Conference on Intelligent Systems in Molecular Biology was truly an outstanding event. Computational methods in molecular biology have reached a new level of maturity and utility, resulting in many high-impact applications. The success of this meeting bodes well for the rapid and continuing development of computational methods, intelligent systems and information-based approaches for the biosciences. The basic technology, originally most often applied to 'feasibility' problems, is now dealing effectively with the most difficult real-world problems. Significant progress has been made in understanding protein-structure information, structural classification, and how functional information and the relevant features of active-site geometry can be gleaned from structures by automated computational approaches. The value and limits of homology-based methods, and the ability to classify proteins by structure in the absence of homology, have reached a new level of sophistication. New methods for covariation analysis in the folding of large structures such as RNAs have shown remarkably good results, indicating the long-term potential to understand very complicated molecules and multimolecular complexes using computational means. Novel methods, such as HMMs, context-free grammars and the uses of mutual information theory, have taken center stage as highly valuable tools in our quest to represent and characterize biological information. A focus on creative uses of intelligent systems technologies and the trend toward biological application will undoubtedly continue and grow at the 1996 ISMB meeting in St Louis.

Expansion of the aminoglycoside-resistance 16S rRNA (m(1)A1408) methyltransferase family: expression and functional characterization of four hypothetical enzymes of diverse bacterial origin.

2014-09-01

The global dissemination, potential activity in diverse species and broad resistance spectrum conferred by the aminoglycoside-resistance ribosomal RNA methyltransferases make them a significant potential new threat to the efficacy of aminoglycoside antibiotics in the treatment of serious bacterial infections. The N1 methylation of adenosine 1408 (m(1)A1408) confers resistance to structurally diverse aminoglycosides, including kanamycin, neomycin and apramycin. The limited analyses to date of the enzymes responsible have identified common features but also potential differences in their molecular details of action. Therefore, with the goal of expanding the known 16S rRNA (m(1)A1408) methyltransferase family as a platform for developing a more complete mechanistic understanding, we report here the cloning, expression and functional analyses of four hypothetical aminoglycoside-resistance rRNA methyltransferases from recent genome sequences of diverse bacterial species. Each of the genes produced a soluble, folded protein with a secondary structure, as determined from circular dichroism (CD) spectra, consistent with enzymes for which high-resolution structures are available. For each enzyme, antibiotic minimum inhibitory concentration (MIC) assays revealed a resistance spectrum characteristic of the known 16S rRNA (m(1)A1408) methyltransferases and the modified nucleotide was confirmed by reverse transcription as A1408. In common with other family members, higher binding affinity for the methylation reaction by-product S-adenosylhomocysteine (SAH) than the cosubstrate S-adenosyl-L-methionine (SAM) was observed for three methyltransferases, while one unexpectedly showed no measurable affinity for SAH. Collectively, these results confirm that each hypothetical enzyme is a functional 16S rRNA (m(1)A1408) methyltransferase but also point to further potential mechanistic variation within this enzyme family.

The XMM/Newton observations of the nearby radio galaxy, Centaurus A, have proven to be a rich data set and has given us new insights into several important processes present in Centaurus A. A list of publications, conference proceedings, and conference abstracts related to these data are attached at the end of this document. We have used the XMM/Newton observations to study the interaction between the relativistic, radio emitting plasma emitted from active nuclei with the hot interstellar medium. Centaurus A is the nearest radio galaxy, so that we have been able to study these features at a linear resolution unattainable for any similar object.

Yang, Bin; Lesicko, John; Moy, Austin J.; Reichenberg, Jason; Tunnell, James W.

2016-02-01

Skin diseases are typically associated with underlying biochemical and structural changes compared with normal tissues, which alter the optical properties of the skin lesions, such as tissue absorption and scattering. Although widely used in dermatology clinics, conventional dermatoscopes don't have the ability to selectively image tissue absorption and scattering, which may limit its diagnostic power. Here we report a novel clinical skin imaging technique called color spatial frequency domain imaging (cSFDI) which enhances contrast by rendering color spatial frequency domain (SFD) image at high spatial frequency. Moreover, by tuning spatial frequency, we can obtain both absorption weighted and scattering weighted images. We developed a handheld imaging system specifically for clinical skin imaging. The flexible configuration of the system allows for better access to skin lesions in hard-to-reach regions. A total of 48 lesions from 31 patients were imaged under 470nm, 530nm and 655nm illumination at a spatial frequency of 0.6mm^(-1). The SFD reflectance images at 470nm, 530nm and 655nm were assigned to blue (B), green (G) and red (R) channels to render a color SFD image. Our results indicated that color SFD images at f=0.6mm-1 revealed properties that were not seen in standard color images. Structural features were enhanced and absorption features were reduced, which helped to identify the sources of the contrast. This imaging technique provides additional insights into skin lesions and may better assist clinical diagnosis.

Polarization sensitive (PS) OCT measures the polarization states of the light backscattered by tissue and provides measures of tissue birefringence and depolarization in addition to the structural OCT signal. Ex vivo studies have demonstrated that birefringence is increased in tissue rich in collagen and with elevated smooth muscle cell content. Preliminary data further suggests that depolarization can identify regions of macrophage infiltration, lipid, and irregularly arranged collagen fibers. These are important aspects of the mechanical integrity and vulnerability of atherosclerotic plaques. To evaluate the potential of PS-OCT in the clinical setting, we combined our custom PS-OCT system with commercially available OCT catheters (Fastview, Terumo Corporation) and performed a pilot study in 30 patients, scheduled to undergo percutaneous coronary intervention (PCI) on the grounds of stable or unstable angina. A total of 82 pullbacks in 39 vessels were performed, either in the native coronary arteries or post procedure. Comparing consecutive pullbacks of the same coronary artery, we found excellent agreement between the polarization features in the repeat pullbacks, validating the repeatability and robustness of PS-OCT in the clinical in vivo setting. In addition we observed that the birefringence and depolarization features vary significantly across lesions with identical structural OCT appearance, suggesting morphological subtypes. This first human pilot study proved the feasibility and robustness of intravascular PS-OCT. PS-OCT achieves improved tissue characterization and may help in identifying high-risk plaques, with the potential to ultimately improve risk stratification and help guiding PCI.

Social media is the interaction among people in which they create, share or exchange information and ideas in virtual communities and web-based networks. This year, the Irish Society of Urology (ISU) expanded its involvement in social media with a preregistered Twitter hashtag (#ISU14) for the annual meeting. The aim of this study was to highlight the use of Twitter at an annual national meeting held in 2014. The Symplur healthcare analytics website was used to prospectively examine traffic related to the 2014 ISU Annual Meeting. This feature was used to generate statistics for the number of impressions, unique tweets (excluding retweets) and distinct contributors who used the indexing hashtag #ISU14. Individual tweets were assessed using the conference hashtag on the Twitter website. The total number of attendees at the conference was 119, and 99 individuals participated in Twitter using the conference hashtag (#ISU14). 31 % of attendees participated in tweeting at the conference. Over the course of the conference, a total of 798 unique tweets were generated, creating over 665,000 impressions in cyberspace. 590 (73.9 %) tweets were generated from attendees at the conference, while 26.1 % of tweets were from virtual followers. 702 (87.9 %) tweets were from urologists and 439 (55 %) tweets were of scientific nature. Tweet activity peaked during the guest lectures on both days. Twitter use at the ISU has been shown to facilitate interaction between delegates and allows users to follow as well as participate from afar.

The majority of plant disease resistance (R) genes encode proteins that share common structural features. However, the transcription activator-like effector (TALE)-associated executor type R genes show no considerable sequence homology to any known R genes. We adopted a map-based cloning approach and TALE-based technology to isolate and characterize Xa23, a new executor R gene derived from wild rice (Oryza rufipogon) that confers an extremely broad spectrum of resistance to bacterial blight caused by Xanthomonas oryzae pv. oryzae (Xoo). Xa23 encodes a 113 amino acid protein that shares 50% identity with the known executor R protein XA10. The predicted transmembrane helices in XA23 also overlap with those of XA10. Unlike Xa10, however, Xa23 transcription is specifically activated by AvrXa23, a TALE present in all examined Xoo field isolates. Moreover, the susceptible xa23 allele has an identical open reading frame of Xa23 but differs in promoter region by lacking the TALE binding element (EBE) for AvrXa23. XA23 can trigger a strong hypersensitive response in rice, tobacco, and tomato. Our results provide the first evidence that plant genomes have an executor R gene family of which members execute their function and spectrum of disease resistance by recognizing the cognate TALEs in the pathogen.

PURPOSE We wanted to identify what organizational features support innovation in Primary Care Groups (PCGs). METHODS Our study used a whole system participatory action research model. Four research teams provided complementary insights. Four case study PCGs were analyzed. Two had an intervention to help local facilitators reflect on their work. Data included 70 key informant interviews, observations of clinical governance interventions and committee meetings, analysis of written materials, surveys and telephone interviews of London Primary Care Organizations, interviews with 20 nurses, and interviews with 6 finance directors. A broad range of stakeholders reviewed data at annual conferences and formed conclusions about trustworthy principles. Sequential research phases were refocused in the light of these conclusions and in response to the changing political context. RESULTS Five features were associated with increased organizational capacity for innovation: (1) clear structures and a vision for corporate and clinical governance; (2) multiple opportunities for people to reflect and learn at all levels of the organization, and connections between these “learning spaces”; (3) both clinicians and managers in leadership roles that encourage participation; (4) the right timing for an initiative and its adaptation to the local context; and (5) external facilitation that provides opportunities for people to make sense of their experiences. Low morale was commonly attributed to 3 features: (1) overwhelming pace of reform, (2) inadequate staff experience and supportive infrastructure, and (3) financial deficits. CONCLUSIONS These features together may support innovation in other primary care bureaucracies. The research methodology enabled people from different backgrounds to make sense of diverse research insights. PMID:16046563

2005-07-01

In this paper, we present a virtual viewpoint video synthesis algorithm to satisfy the following three aims: low computing consuming; real time interpolation and acceptable video quality. In contrast with previous technologies, this method obtain incompletely 3D structure using neighbor video sources instead of getting total 3D information with all video sources, so that the computation is reduced greatly. So we demonstrate our interactive multi-view video synthesis algorithm in a personal computer. Furthermore, adopting the method of choosing feature points to build the correspondence between the frames captured by neighbor cameras, we need not require camera calibration. Finally, our method can be used when the angle between neighbor cameras is 25-30 degrees that it is much larger than common computer vision experiments. In this way, our method can be applied into many applications such as sports live, video conference, etc.

Informed and shared decision making are critical aspects of patient-centered care, which has contributed to an emphasis on decision support interventions to promote good medical decision making. However, researchers and healthcare providers have not reached a consensus on what defines a good decision, nor how to evaluate it. This position paper, informed by conference sessions featuring diverse stakeholders held at the 2015 Society of Behavioral Medicine and Society for Medical Decision Making annual meetings, describes key concepts that influence the decision making process itself and that may change what it means to make a good decision: interpersonal factors, structural constraints, affective influences, and values clarification methods. This paper also proposes specific research questions within each of these priority areas, with the goal of moving medical decision making research to a more comprehensive definition of a good medical decision, and enhancing the ability to measure and improve the decision making process.

The power of synthetic biology has enabled the expression of heterologous pathways in cells, as well as genome-scale synthesis projects. The complexity of biological networks makes rational de novo design a grand challenge. Introducing features that confer genetic flexibility is a powerful strategy for downstream engineering. Here we develop an in vitro method of DNA library construction based on structural variation to accomplish this goal. The "in vitro SCRaMbLE system" uses Cre recombinase mixed in a test tube with purified DNA encoding multiple loxPsym sites. Using a β-carotene pathway designed for expression in yeast as an example, we demonstrate top-down and bottom-up in vitro SCRaMbLE, enabling optimization of biosynthetic pathway flux via the rearrangement of relevant transcription units. We show that our system provides a straightforward way to correlate phenotype and genotype and is potentially amenable to biochemical optimization in ways that the in vivo system cannot achieve.

This document is a compilation of papers presented at the Mechanics of Textile Composites Conference in Hampton, Virginia, December 6-8, 1994. This conference was the culmination of a 3-year program that was initiated by NASA late in 1990 to develop mechanics of textile composites in support of the NASA Advanced Composites Technology Program (ACT). The goal of the program was to develop mathematical models of textile preform materials and test methods to facilitate structural analysis and design. Participants in the program were from NASA, academia, and industry.

PREFACE: 1982 International Conference on Plasma Physics

Wilhelmsson, Hans

1982-01-01

Invited Papers: The Physics of Hot Plasmas During the last decade a dramatic evolution of plasma physics has occurred. Not only have gigantic fusion plasma machines been planned, and are now being built, and elaborate spaceships and antenna systems been constructed to explore remote parts of the cosmos; new observations have revealed fascinating structures in space, ranging from pulsar plasmas under extreme conditions in very strong magnetic fields to large-scale magnetic field and electric current systems in cosmic plasmas. X-rays from very distant sources as well as radio-waves from the plasma in the magnetosphere and in the Aurora have recently been studied with new observational techniques. Ingenious laboratory experiments are continuously being carried out to exploit new fundamental processes in plasmas. These are of great interest for the basic understanding of plasmas and also have immediate consequences for applications, like plasma heating and diagnostics. The theoretical description of new plasma phenomena, and of the plasma state in general poses challenging problems, particularly in situations where high concentration of energy is located in the plasmas. Nonlinear wave analysis and turbulence theory have accordingly been extensively developed to describe in particular the collective plasma phenomena. New concepts have been envisaged like plasma solitons, which may be thought of as excitations of local concentrations of longitudinal plasma waves which turn out to be particularly stable. More and more sophisticated structures of nonlinear nature are being revealed by means of high capacity computer facilities. Simulation experiments allow for studies of chaotic behaviour of plasma particles. Related fields of activity form new trends in the development of plasma theory. The programme of the 1982 International Conference on Plasma Physics, which was held in Göteborg, Sweden, stressed the role of the Physics of Hot Plasmas. Studies of such plasmas are essential, not only for fusion energy development, but also for astro- and space research. Plasmas in different situations often have important features in common. Results obtained under various conditions, in the laboratory or in space, should therefore be compared and interrelated. The Göteborg conference emphasized more than the previous one, which was held in Nagoya, Japan, the astro- and space aspects, but there were still more contributions from the fusion and laboratory research. The fundamental plasma theory part was, however, the most extensive one in the programme. At the conference there were seventy invited talks, including six comprehensive talks addressed to all participants. The remaining sixtyfour invited talks were topical talks. Besides, we had received about 450 contributed papers. About 300 of them were given as posters, and most of the remaining ones were presented as orals. The set of one page abstracts of these contributed papers as well as the titles of the invited talks were collected in two volumes, which were sent to all participants a month before the conference. Another set, the four page papers, which had been carefully prepared by the authors for photoreproduction to one page papers, were published in a volume of proceedings of some 460 pages available at the conference. When trying to classify the contributions, it turned out that they fell naturally into four main categories, namely: General Theory Space and Astro Plasmas Fusion Laboratory Plasmas For practical reasons we had to divide the Abstracts into two Volumes, the first one including categories (1) and (2), and the second one the two remaining categories (3) and (4). In publishing the invited talks from the conference we had to handle a great number of extensive papers. It turned out to be natural to have also the invited papers published in two parts, as two separate numbers of Physica Scripta, the first one devoted to (1) General Theory, and (2) Space and Astro Plasmas, whereas the second one to (3) Fusion and (4) Laboratory Plasmas. The 1982 International Conference on Plasma Physics was organized by Chalmers University of Technology. It gathered about 500 participants from 40 countries. Large delegations came from the USA, France, West Germany, Japan, the USSR, and India, the number of participants from these countries ranging from 100 to 20. Sweden had about 50 participating scientists. There were a total of about 20 from the other Scandinavian countries. The principal sponsor of the conference was IUPAP, the International Union of Pure and Applied Physics. The conference also had a number of co-sponsors like IAU, the International Astronomical Union, URSI, the International Union of Radio Science, EPS, the European Physical Society, and EURATOM-FUSION. The conference was supported by Swedish Industry and Swedish Research Boards. The previous ICPP, held in Nagoya two years ago, was the first attempt to combine two types of conferences: the Plasma Theory Conference, first held in Kiev in the Soviet Union in 1971, and the Waves and Instabilities Congress, held for the first time in Innsbruck, Austria in 1973. As a consequence of the success of the Nagoya conference it was decided by the International Organizing Committee of the ICPP that the 1982 conference should also be of the combined type. The 1982 ICPP in Göteborg was thus a Joint Conference of the Fifth Kiev International Conference in Plasma Theory and the Fifth International Congress on Waves and Instabilities in Plasmas. During the conference in Göteborg the International Organizing Committee had a meeting and it was decided that also the next International Conference on Plasma Physics will be of the combined type. It will be held in Lausanne, Switzerland in 1984. The International Organizing Committee on the 1982 International Conference on Plasma Physics comprised about 40 plasma physics scientists from all over the world, who represented various sections of plasma physics. I would like to thank the active members of the IOC for an efficient and friendly co-operation in deciding about the program of invited speakers and for discussions on the general structure of the conference. Our most cordial thanks are extended to the invited speakers for coming to the conference to deliver such excellent talks and to provide us in good time for printing with so beautifully prepared manuscripts. Symposium on Plasma Theory: Preface Several satellite meetings were arranged following the 1982 International Conference on Plasma Physics in Göteborg. Among them a Symposium on Plasma Theory was held at Aspenäsgården outside Göteborg during three days, June 16-18, 1982. The purpose of the symposium was to discuss problems of current interest in plasma theory with applications to space and astrophysical plasmas as well as to fusion plasmas. A total of fifteen talks were given during the three days, and some very lively discussions arose, notably in the area of plasma turbulence. There were around 30 invited scientists present, about one third from the United States, one third from the Soviet Union, and the rest from England, Japan, and various other countries. This volume of Physica Scripta (2B, 506-595) includes some of the talks which were given at Aspenäsgården. Several of the authors of contributed papers to the 1982 International Conference on Plasma Physics were encouraged to write extended versions of their contributions, and these are also included in this number, as are furthermore some papers, which were prepared during prolonged stays of visiting scientists at our institute in connection with the 1982 ICPP. It is expected that the collection of papers thus assembled will give a general picture of the activities accompanying the main conference and that it will elucidate some trends in the development of plasma theory.

Purpose Research of employer policies and practices to manage and prevent disability spans many disciplines and perspectives, and there are many challenges related to stakeholder collaboration, data access, and interventions. The purpose of this article is to synthesize the findings from a conference and year-long collaboration among a group of invited researchers intended to spur new research innovations in this field. Methods A multidisciplinary team of 26 international researchers with published research in employer-based disability management or related fields were invited to attend a 3-day conference in Hopkinton, Massachusetts, USA. The conference goals were to review the status of current research of workplace disability management and prevention, examine its relevance for employer decision-making, compare conceptual frameworks or theoretical perspectives, and recommend future research directions. In this paper, we summarize key points from the 6 resulting papers, compare them with an earlier 2005 conference on improving return-to-work research, and conclude with recommendations for further overarching research directions. Results/Conclusion In comparison with the 2005 conference, a greater emphasis was placed on organizational and social factors, employer roles and responsibilities, methods of implementation, non-clinical approaches, and facilitating stay-at-work as well as return-to-work. A special panel of employer consultants and representatives who were featured at the 2015 conference reinforced the importance of organizational culture, leadership style, and financial decision-making strategies at the employer level. Based on the conference proceedings, we recommend that future research in this area should strive for: (a) broader inclusion of workers and workplaces; (b) attention to multilevel influences in the workplace; (c) a focus on social as well as physical aspects of work; (d) earlier employer collaboration efforts; (e) more attention to implementation factors; and (f) a broader assessment of possible outcome domains.

FOREWORD: Nuclear Physics in Astrophysics V

Auerbach, Naftali; Hass, Michael; Paul, Michael

2012-02-01

The fifth edition of the bi-annual 'Nuclear Physics in Astrophysics (NPA)' conference series was held in Eilat, Israel on April 3-8, 2011. This Conference is also designated as the 24th Nuclear Physics Divisional Conference of the EPS. The main purpose of this conference, as that of the four previous ones in this series, is to deal with those aspects of nuclear physics that are directly related to astrophysics. The concept of such a meeting was conceived by the Nuclear Physics Board of the European Physical Society in 1998. At that time, the idea of such a conference was quite new and it was decided that this meeting would be sponsored by the EPS. The first meeting, in January 2001, was planned and organized in Eilat, Israel. Due to international circumstances the conference was moved to Debrecen, Hungary. Subsequent conferences were held in Debrecen again, in Dresden, Germany, and in Frascati, Italy (moved from Gran Sasso due to the tragic earthquake that hit the L'Aquila region). After 10 years the conference finally returned to Eilat, the originally envisioned site. Eilat is a resort town located on the shore of the Gulf of Eilat, which connects Israel to the Red Sea and further south to the Indian Ocean. It commands spectacular views of the desert and mountains, offering unique touristic attractions. The local scientific backdrop of the conference is the fact that the Israeli scientific scene exhibits a wide variety of research activities in many areas of nuclear physics and astrophysics. A new accelerator, SARAF at Soreq Nuclear Research Center is presently undergoing final acceptance tests. SARAF will serve as a platform for production of radioactive ion beams and nuclear-astrophysics research in Israel. The meeting in Eilat was organized by four Israeli scientific institutions, Hebrew University, Soreq Nuclear Research Center, Tel Aviv University and the Weizmann Institute of Science. The welcome reception and lectures were held at the King Solomon hotel and the conference dinner banquet at the Dan hotel. An excursion to the 'Red Canyon' in the Eilat Mountains on Wednesday afternoon was one of the social highlights of the conference. A total number of 140 scientists attended NPA5 and about 30 accompanying persons; about 25% of these were young participants (less than 36 years old). 23 participants were from Israel, and 27 were from outside of Europe (including two from Africa). The subjects covered at the conference in Eilat concentrated mainly on the spirit of the original idea - to probe experimental and theoretical activity in nuclear structure and reactions that is directly related to the physics of the Universe. There were also sessions of general interest in astrophysics, as well as a poster session on Tuesday evening featuring 40 posters. The topics included: Nuclear Structure - Theory and Experiment Big-Bang Nucleosynthesis and Formation of First Stars Stellar Reactions and Solar Neutrinos Explosive Nucleosynthesis, Radioactive Beams and Exotic Nuclei-New Facilities and Future Possibilities for Astrophysics Neutrino Physics - the Low and High-Energy Frontiers Rare events, Dark Matter, Double beta-decay, Symmetries The conference started with an excellent exposé of the progress made in the discovery of super-heavy elements and the study of their properties. The progress in this field is enormous, and this subject should be communicated to more general audiences. The role of the nuclear equation of state and of the precise determination of nuclear masses in nucleosynthesis was emphasized in several talks. The role of neutrinos in astrophysics was discussed extensively in several sessions. One of the highlights of this was the presentation about the IceCube and DeepCore detectors operating deep in the Antarctic ice. These facilities are able to detect cosmogenic neutrinos in a wide energy range, from 10 GeV to 1010 GeV. The subject of solar neutrinos was discussed in a number of talks. Topics related to properties of neutrinos, such as double-beta decay and neutrino mixing were well represented at the conference. One of the central problems in modern cosmology and astrophysics is the search for dark matter. Several talks dealt with this subject and with methods to detect dark matter. Another intriguing and rather novel subject that was discussed at the meeting was time variation of fundamental physical constants. Two speakers have examined the sensitivity of Big-Bang Nucleosynthesis to the variation of the values of the fundamental constants. The role of some specific nuclei (such as Ni 56) in cosmology was pointed out. Many of the presentations at the conference described experimental studies of reactions relevant to nucleosynthesis at various stages of cosmic evolution. As reflected in the conference, these activities are widespread, encompassing many laboratories. Rare Isotope Beam (RIB) facilities are in the forefront of these studies. To understand the various processes of nucleosynthesis one has to have a good theory of nuclei far from the stability line. A number of presentations dealt with the description of such exotic nuclei. It is clear from the presentations that the future of experimental nuclear astrophysics looks promising as existing experimental facilities are being upgraded and new facilities are being built. X-Ray and Gamma-Ray Bursts and cosmic explosions were the subject of several talks. A discussion of various experiments attempting to measure time-reversal violation was the subject of one lecture. The solution of the puzzle as to why the universe is asymmetric with respect to matter-antimatter requires knowledge of the limit of time-reversal conservation. The late John Bahcall was a great astrophysicist and a supporter of the conference series 'Nuclear physics in Astrophysics'. On the last day of the conference, following a talk by Neta Bahcall from Princeton University on dark matter in the Universe, a short commemoration for John was held.

Summary Ponatinib is the only currently approved tyrosine kinase inhibitor (TKI) that suppresses all BCR-ABL1 single mutants in Philadelphia chromosome-positive (Ph+) leukemia, including the recalcitrant BCR-ABL1T315I mutant. However, emergence of compound mutations in a BCR-ABL1 allele may confer ponatinib resistance. We found that clinically reported BCR-ABL1 compound mutants center on 12 key positions and confer varying resistance to imatinib, nilotinib, dasatinib, ponatinib, rebastinib and bosutinib. T315I-inclusive compound mutants confer high-level resistance to TKIs, including ponatinib. In vitro resistance profiling was predictive of treatment outcomes in Ph+ leukemia patients. Structural explanations for compound mutation-based resistance were obtained through molecular dynamics simulations. Our findings demonstrate that BCR-ABL1 compound mutants confer different levels of TKI resistance, necessitating rational treatment selection to optimize clinical outcome. PMID:25132497

The Global Precipitation Patterns Associated with Short-Term Extratropical Climate Fluctuations

NASA Technical Reports Server (NTRS)

Huffman, George J.; Adler, Robert F.; Bolvin, David T.

1999-01-01

Two globally-complete, observation-only precipitation datasets have recently been developed for the Global Precipitation Climatology Project (GPCP). Both depend heavily on a variety of satellite input, as well as gauge data over land. The first, Version 2x79, provides monthly estimates on a 2.5 deg. x 2.5 deg. lat/long grid for the period 1979 through late 1999 (by the time of the conference). The second, the One-Degree Daily (1DD), provides daily estimates on a 1 deg. x l deg. grid for the period 1997 through late 1999 (by the time of the conference). Both are in beta test preparatory to release as official GPCP products. These datasets provide a unique perspective on the hydrological effects of the various atmospheric flow anomalies that have been identified by meteorologists. In this paper we discuss the regional precipitation effects that result from persistent extratropical flow anomalies. We will focus on the Pacific-North America (PNA) and North Atlantic Oscillation (NAO) patterns. Each characteristically becomes established on synoptic time scales, but then persists for periods that can exceed a month. The onset phase of each appears to have systematic mobile features, while the mature phase tend to be more stationary. Accordingly, composites of monthly data for outstanding positive and negative events (separately) contained in the 20-year record reveal the climatological structure of the precipitation during the mature phase. The climatological anomalies of the positive, negative, and (positive-negative) composites show the expected storm-track-related shifts in precipitation, and provide the advantage of putting the known precipitation effects over land in the context of the total pattern over land and ocean. As well, this global perspective points out some unexpected areas of correlation. Day-by-day composites of daily data anchored to the onset date demonstrate the systematic features during the onset. Although the 1DD has a fairly short record, some preliminary results are shown and compared to previous work with numerical weather prediction models.

We will focus on the Pacific-North America (PNA) and North Atlantic Oscillation (NAO) patterns. Each characteristically becomes established on synoptic time scales, but then persists for periods that can exceed a month. The onset phase of each appears to have systematic mobile features, while the mature phase tend to be more stationary. Accordingly, composites of monthly data for outstanding positive and negative events (separately) contained in the 20-year record reveal the climatological structure of the precipitation during the mature phase. The climatological anomalies of the positive, negative, and (positive-negative) composites show the expected storm-track-related shifts in precipitation, and provide the advantage of putting the known precipitation effects over land in the context of the total pattern over land and ocean. As well, this global perspective points out some unexpected areas of correlation. Day-by-day composites of daily data anchored to the onset date demonstrate the systematic features during the onset. Although the 1DD has a fairly short record, some preliminary results are shown and compared to previous work with numerical weather prediction models.

The primary role of mitochondria was long considered to be production of cellular energy. However, as the understanding of mitochondria in disease is ever expanding, so is their additional function for a healthy organism. Mitochondrial dysfunction is linked to a range of pathologies, including cancer, neurodegenerative disorders, premature aging, diabetes and muscular diseases. Mitochondrial diseases can be hard to diagnose and treat and, therefore, interdisciplinary research and communication are important. The Third Annual Conference of Society for Mitochondrial Research and Medicine - India (SMRM) was titled "Mitochondria in Health and Disease". The conference was organized by Gayathri N, K Thangaraj, and KK Singh and was held at the National Institute of Mental Health & Neuro Sciences (NIMHANS) in Bangalore, India, from the 19th to 20th of December 2013. The meeting featured internationally renowned speakers within the field of mitochondrial research and medicine with the goal of bridging the gap between basic and clinical researchers. This review summarizes key outcomes of the conference. Copyright © 2014 © Elsevier B.V. and Mitochondria Research Society. Published by Elsevier B.V. All rights reserved.

Developments in the connected fields of optics, optoelectronics and photonics have had a profound effect on the emergence of modern technologies and their influence on our lives. In all of these fields, understanding and improving the basic underlying materials is of crucial importance for the development of systems and applications. The International Conference on Optical, Optoelectronic and Photonic Materials and Applications (ICOOPMA) has successfully married these fields and become a regular feature in the conference calendar. The 6th conference in the series, held at the University of Leeds from 27th July - 1st August, 2014, continued the ICOOPMA tradition and attracted 220 international delegates with a diverse range of disciplines and interests. The 59 papers in this Proceedings provide an excellent overview of the topics presented. The conference consisted of four thematic areas in the fields of inorganic semiconductors, carbon and polymeric materials, inorganic glasses and crystalline materials, and metamaterials and plasmonics where each theme area included research on basic materials through to device applications. The conference began with a Workshop organised by Professor Dan Hewak (University of Southampton) with speakers covering Organic Optoelectronic Complexes (Dr Richard Curry, University of Surrey), Metamaterials (Dr Vassili Fedotov, University of Southampton), Graphene (Dr Monica Craciun, University of Exeter) and Amorphous Semiconductors (Dr Jiri Orava, University of Cambridge and Tohoku University). This provided an excellent overview of a representative range of the important topics that were discussed further at the conference. The conference included a banquet which successfully combined excellent food with a relaxing opportunity for the conference delegates to socialise and network. The pinnacle of the evening was the after dinner speech given by our distinguished guest, Professor Sir David Payne (University of Southampton), who gave a highly informative and humorous history of the development of photonics and the important role played by optical fibres, of which he was one of the key pioneers. Emerging scientific talent was also given a platform, with a particular feature of the conference being the Young Scientists Forum, organised by Dr Senthil Ganapathy (University of Southampton), consisting of a series of themed sessions providing up-and-coming researchers a opportunity to present and discuss their work. Each technical theme of the conference was introduced with Plenary lectures delivered by leading international figures in their respective fields. Professor Jim Harris (Stanford University) discussed the development of epitaxially grown dilute-nitride semiconductors and the important role that they play in high efficiency solar cells. This theme was continued by Professor Wolfgang Stolz (Philipps University, Marburg) who described the use of novel III-V semiconductors for the development of lasers on silicon. Dr Jerry Meyer (Naval Research Laboratories) and Dr Kumar Patel (Pranalytica) discussed the important field of mid-infrared devices highlighting the significant developments that have been made in inter-band cascade and quantum cascade based devices, respectively and which have wide-ranging applications in sensing. Professor Neil Greenham (University of Cambridge) discussed solution-based semiconductors based on conjugated polymers and nanocrystals offering low cost routes to the wide-scale deployment of photonics. Professor Ortwin Hess (Imperial College) gave an overview of the physics and fascinating technological potential of negative refractive index materials. Professor Stephen Elliott (University of Cambridge) discussed the optoelectronic properties of phase change materials for memories. These areas were expanded upon in over 70 invited talks from international speakers highlighting recent developments in each of these areas. Further detailed discussions were presented in many parallel Oral and Poster sessions. This Proceedings provides an exciting and wide-ranging discussion of the topics presented at ICOOPMA 2014. We are very grateful to the many people who helped with the organisation of the conference, with particular thanks to Alison Whiteley and her team who enabled the smooth running of the conference, Dr Senthil Ganapathy for his many and wide ranging contributions to the conference and finally Professor Safa Kasap for his wisdom, advice and strong support. The conference could not have happened without the commitment of the Local Organising Committee, who helped in many ways to assemble and run the conference, and for the International Programme, Advisory and Steering committees who guided the technical direction of the conference and assisted with the conference programme and proceedings. We are also extremely pleased to have received generous sponsorship from a large number of organisations and companies. Finally, we are also very grateful to Sarah Toms and the Editorial staff at the Institute of Physics, and the many contributors and reviewers for helping us to put-together this proceedings.

EDITORIAL: Special cluster on Dielectrics for Emerging Technologies

Clarke, R.; Youngs, I.; Stevens, G.

2004-02-01

The 2003 Conference on Dielectrics for Emerging Technologies was organised by the Institute of Physics Dielectrics Group as one of the participating conferences at the IOP Physics Congress held at Heriot-Watt University between 23 and 27 March 2003. This was the second annual conference of the new Dielectrics Group, which was formed from the former Dielectrics Society in October 2001. The conference policy remains unchanged, with the Group adopting an interdisciplinary and broadband approach to studies of the interaction of electromagnetic fields with materials. This policy is well exemplified by the papers that were delivered at this conference. The aims of the conference were three-fold: to provide a forum for the presentation of leading-edge research on emerging electromagnetic materials, to present developments on the use of dielectrics in emerging technologies and to broaden the debate on metamaterials in the UK, especially in relation to their potential applications. The metamaterials of interest here are macro- or meso-scopically structured materials that offer novel modes of electromagnetic field interaction, thereby widening the range of effective dielectric properties available to us for novel technological applications. They include `negative refractive index materials', `left handed materials', `photonic' or `electromagnetic band-gap materials' and actively-controlled or `smart' electromagnetic materials. Significant metamaterial applications are anticipated in the development of `perfect' lenses, filters, wavefront-conditioning layers and in improved metrology. The conference focussed additionally on dielectrics in support of electronics, photonics and optics, nano-materials, composites and structures, and the development of tuneable dielectrics and resonators for future applications in telecommunications. We are pleased to report that the conference was successful in achieving its objectives, thirty-four oral papers were delivered and twenty-three poster papers presented, many of which provoked significant debate. All contributions and the vigorous discussions held in this predominantly international forum testify to the health and vigour of this branch of materials physics and engineering. We were particularly pleased on this occasion to have the opportunity to run joint conference sessions with the `Structured Optical Materials' and `Electrostatics' conferences, which were run in parallel at the Congress. Electromagnetic materials science is inherently a cross-spectrum discipline and these sessions demonstrated the considerable overlap of technical interests and research from DC to optical frequencies. We are delighted to have the privilege of presenting eleven of the papers from the conference in this special cluster of Journal of Physics D: Applied Physics. Between them they capture the wide range of topics that were covered at the conference. The field of dielectric materials characterisation was well represented and amongst many other topics it included the study of nano-composites, represented here by the papers of Pelster et al and Hussain et al. Composite dielectrics at all scales lie at the centre of most new research into emerging applications and the paper by Bowler and that of Tuncer are also concerned with the understanding and characterisation of such materials. The understanding of the nature and distribution of space charge has always been a core dielectric study and a contribution to this field is made here by the paper of Marat-Mendes et al. Processing is a major factor that governs the properties of all dielectric materials---but this is particularly true in the case of sintered low-loss ceramics. The paper of Pullar et al adds to our knowledge in this important area. The remit of the conference led to the discussion of a very wide range of potential applications. One such is the use of dielectrophoretic forces for separating particles in suspensions (e.g. in pharmaceutical and diagnostic applications). The paper by Flores-Rodriguez and Markz presents a study on one aspect of this discipline. Presentations on meta- and structured materials at the conference are represented here in two papers: those of Shamonina and Solymar and of Zhou, Chan and Sheng, while a study in the closely allied area of band-gap materials is presented in the paper by Schuster and Klein. The final paper from the conference in this special cluster is concerned with an end-use application: the use of tuneable dielectric resonators in base-stations for future mobile telecoms networks. The paper by Krupka et al describes a magnetic approach to such tuning. In the longer term we sincerely hope that both the conference and these papers will prove to have made a significant contribution to the development and uses of dielectrics, and their metamaterial derivatives, in advanced technological applications. It is noteworthy that as a result of the success of this conference, the 2004 annual conference will be on the subject of `Dielectrics at Meso- and Nano-Scales'. We would like to take this opportunity to express our sincere thanks to all who participated in the conference for their contributions and we would like to express our particular thanks to the authors of the papers in this special cluster of Journal of Physics D: Applied Physics.

Wisdom of the Crowds: Crowd-Based Development of a Logo for a Conference Using a Crowdsourcing Contest.

Crowdsourcing methods have been widely used in business, but rarely in sexual health research. We evaluated a crowdsourced logo contest as part of an international human immunodeficiency virus conference. A logo crowdsourcing contest was conducted for the 20th International Acquired Immunodeficiency Syndrome Conference. Crowdsourcing has a group of individuals solve a task, often as part of an open contest. Semistructured interviews were conducted with key informants including contest organizers, contest contributors, and conference attendees. Interviews were transcribed verbatim and analysed using a content analysis approach. In total, 22 interviews were conducted with 3 contest organizers, 7 contest contributors, and 12 conference attendees. All individuals reported that the crowdsourced logo provided benefits beyond branding the conference, including creating a shared sense of purpose among diverse conference participants and explicitly demonstrating the strong community orientation of the conference. Conference organizers and attendees all reported deeper engagement because of the story of the Tanzanian artist who won the contest. Most conference attendees (11/12) preferred the crowdsourced logo compared with the previous company-organized logo, and all (22/22) supported the logo contest continuing. Implementing a logo contest was simple and relatively inexpensive. Stakeholders identified several ways to enhance crowdsourcing logo contest methods including wider promotion of the contest to encourage broader participation, greater transparency in the selection process, and a different prize structure which acknowledges the contribution of more contestants. We found that a crowdsourcing contest helped engage local and global communities in the lead-up before and during an international conference. Similar participatory events may be useful for sexual health conferences and research projects.

Abstract Two conferences, Creating More Compassionate Systems of Care (November 2012) and On Improving the Spiritual Dimension of Whole Person Care: The Transformational Role of Compassion, Love and Forgiveness in Health Care (January 2013), were convened with the goals of reaching consensus on approaches to the integration of spirituality into health care structures at all levels and development of strategies to create more compassionate systems of care. The conferences built on the work of a 2009 consensus conference, Improving the Quality of Spiritual Care as a Dimension of Palliative Care. Conference organizers in 2012 and 2013 aimed to identify consensus-derived care standards and recommendations for implementing them by building and expanding on the 2009 conference model of interprofessional spiritual care and its recommendations for palliative care. The 2013 conference built on the 2012 conference to produce a set of standards and recommended strategies for integrating spiritual care across the entire health care continuum, not just palliative care. Deliberations were based on evidence that spiritual care is a fundamental component of high-quality compassionate health care and it is most effective when it is recognized and reflected in the attitudes and actions of both patients and health care providers.

Formerly entitled 'CO2 Fixation and Metabolism in Green Plants', this long-standing Gordon Research Conference has been held on a triennial basis since 1976. In 1990 the participants decided to alternate between sites in the U.S. and outside the U.S. The 2005 conference was held in Europe at the Centre Paul Langevin in Aussois, France, so the 2008 conference returns to a U.S. site - the University of New England in Biddeford, Maine. The 2008 conference covers basic plant research related to photosynthesis and the subsequent regulation and engineering of carbon assimilation. Approaches that range from post-genomic technologies and systems biology,more » through to fundamental biochemistry, physiology and molecular biology are integrated within ecological and agronomic contexts. As such, the meeting provides the rare opportunity of a single venue for discussing all aspects of the 'carbon-side' of photosynthesis - from genome to biome. The 2008 conference will include an emphasis on the central role of carbon assimilation by plants for developing new sources of bioenergy and for achieving a carbon-neutral planet. A special characteristic of this conference is its 'intimacy' with approximately 110 conferees, ranging from beginning graduate students and postdoctoral associates to leading senior plant scientists, engaged in open and forward-thinking discussions in an informal, friendly setting. With extended time devoted to discussion, and the encouragement to challenge dogma, it is unlike other meetings in the U.S. or abroad. Another novel feature of the conference is a session devoted to the latest 'hot off the press' findings by both established and early career scientists, picked from the abstracts. Together with an expanded poster discussion in the evening sessions, this session provides an opportunity for early career scientists to present interesting new data and to 'test drive' hypotheses in a collegial atmosphere.« less

Hydrocarbon double-stapling remedies the proteolytic instability of a lengthy peptide therapeutic

The pharmacologic utility of lengthy peptides can be hindered by loss of bioactive structure and rapid proteolysis, which limits bioavailability. For example, enfuvirtide (Fuzeon, T20, DP178), a 36-amino acid peptide that inhibits human immunodeficiency virus type 1 (HIV-1) infection by effectively targeting the viral fusion apparatus, has been relegated to a salvage treatment option mostly due to poor in vivo stability and lack of oral bioavailability. To overcome the proteolytic shortcomings of long peptides as therapeutics, we examined the biophysical, biological, and pharmacologic impact of inserting all-hydrocarbon staples into an HIV-1 fusion inhibitor. We find that peptide double-stapling confers striking protease resistance that translates into markedly improved pharmacokinetic properties, including oral absorption. We determined that the hydrocarbon staples create a proteolytic shield by combining reinforcement of overall α-helical structure, which slows the kinetics of proteolysis, with complete blockade of peptide cleavage at constrained sites in the immediate vicinity of the staple. Importantly, double-stapling also optimizes the antiviral activity of HIV-1 fusion peptides and the antiproteolytic feature extends to other therapeutic peptide templates, such as the diabetes drug exenatide (Byetta). Thus, hydrocarbon double-stapling may unlock the therapeutic potential of natural bioactive polypeptides by transforming them into structurally fortified agents with enhanced bioavailability.

2003-05-23

The emergence of antibiotic-resistant bacterial strains is a widespread problem in contemporary medical practice and drug design. It is therefore important to elucidate the underlying mechanism in each case. The methyltransferase AviRa from Streptomyces viridochromogenes mediates resistance to the antibiotic avilamycin, which is closely related to evernimicin, an oligosaccharide antibiotic that has been used in medical studies. The structure of AviRa was determined by X-ray diffraction at 1.5A resolution. Phases were obtained from one selenomethionine residue introduced by site-directed mutagenesis. The chain-fold is similar to that of most methyltransferases, although AviRa contains two additional helices as a specific feature. A putative-binding site for the cofactor S-adenosyl-L-methionine was derived from homologous structures. It agrees with the conserved pattern of interacting amino acid residues. AviRa methylates a specific guanine base within the peptidyltransferase loop of the 23S ribosomal RNA. Guided by the target, the enzyme was docked to the cognate ribosomal surface, where it fit well into a deep cleft without contacting any ribosomal protein. The two additional alpha-helices of AviRa filled a depression in the surface. Since the transferred methyl group of the cofactor is in a pocket beneath the enzyme surface, the targeted guanine base has to flip out for methylation.

The Toxoplasma gondii cyst wall protein CST1 is critical for cyst wall integrity and promotes bradyzoite persistence

Toxoplasma gondii infects up to one third of the world’s population. A key to the success of T.gondii is its ability to persist for the life of its host as bradyzoites within tissue cysts. The glycosylated cyst wall is the key structural feature that facilitates persistence and oral transmission of this parasite. We have identified CST1 (TGME49_064660) as a 250 kDa SRS (SAG1 related sequence) domain protein with a large mucin-like domain. CST1 is responsible for the Dolichos biflorus Agglutinin (DBA) lectin binding characteristic of T. gondii cysts. Deletion of CST1 results in a fragile brain cyst phenotype revealed bymore » a thinning and disruption of the underlying region of the cyst wall. These defects are reversed by complementation of CST1. Additional complementation experiments demonstrate that the CST1-mucin domain is necessary for the formation of a normal cyst wall structure, the ability of the cyst to resist mechanical stress and binding of DBA to the cyst wall. RNA-seq transcriptome analysis demonstrated dysregulation of bradyzoite genes within the various cst1 mutants. These results indicate that CST1 functions as a key structural component that reinforces the cyst wall structure and confers essential sturdiness to the T. gondii tissue cyst.« less

Self-help conferences for people who stutter: a qualitative investigation.

PubMed

Trichon, Mitchell; Tetnowski, John

2011-12-01

Self-help activities for people who stutter (PWS) have been gaining in popularity; however, there is a scarcity of evidence to support their utility in stuttering management. The purpose of this investigation was to understand the lived experience of individuals who attended a self-help conference(s) for PWS from the perspective of a PWS to learn its potential utility in stuttering management. The investigator used Interpretive Phenomenological Analysis (IPA) to systematically collect authentic data of this social phenomenon. Twelve participants were recruited from a self-help conference and the self-help community of PWS. Semi-structured interviews were conducted 4-18 months after each participant's last conference. Interviews were transcribed and analyzed. Themes were explained in investigator narratives and illustrated through participants' quotes. Interpreted themes of the experience of having attended a self-help conference(s) for PWS included: socializing opportunities with other PWS, affiliation, redefining oneself and post-conference disclosures. A conclusion of the study was that the experience of having attended a self-help conference(s) for PWS helped to minimize negative impact that stuttering can have on daily functioning. It appears that self-help conferences were perceived as a safer or "stutter-friendly" environment and promoted social interaction, relationship building, and community building through planned and unplanned activities. Another conclusion was that the experience of having attended self-help conferences for PWS helped participants to communicate more easily. Reported increases in social activity and an "openness" about stuttering, suggest self-help conferences' utility in stuttering management. These findings are supported by other studies about successful stuttering management and self-help activities for PWS. They have helped attendees who stutter to communicate more easily and suggest a reduction in the negative impact that stuttering has on their lives. The reader will be able to: (1) describe recurring themes associated with the lived experience having attended a self-help conference(s) for people who stutter (PWS) from the perspective of a group of adults who stutter, and (2) describe the potential benefits of attending self-help conferences for PWS in order to make appropriate evidence-based referrals to self-help conferences for PWS.

It is a great pleasure to welcome you to the 27th International Conference on CADCAM, Robotics and Factories of the Future, sponsored by the International Society for Productivity Enhancement, Middlesex University, Festo Limited GB, National Instruments UK & Ireland, the Sector Skills Council for Science, Engineering and Manufacturing Technologies and our proceedings publisher Institute of Physics Publications. This is the second time Middlesex University has played host to this longstanding international conference, last time being the 12th edition in 1996. The subject content of the conference remains current, focusing on cutting edge developments in research. The conference themes this year are divided into seven themes, Product Development and Sustainability, Modelling and Simulation, Automation, Robotics and Handling Systems, Advanced Quality Systems Tools and Quality Management, Human Aspects in Engineering Activities, Emerging Scenarios in Engineering Education and Training, and Emerging Technologies in Factories of the Future. The conference is organised into seven sessions running in parallel over three days, providing a platform to speakers from 16 different countries. The programme also features four eminent keynote speakers and a hands-on workshop organised by National Instruments. Organising an event such as this would not be possible without the help of many colleagues. I am grateful to the members of the Organising Committee, the International Scientific Committee, our sponsors and all those colleagues who helped in the review of many abstracts and consequently full papers. This required meticulous attention to detail and strict adherence to very tight deadlines. However large or small a conference is, the effort required to make the local arrangements work for all is not insignificant. The conference organisers acknowledge the particular efforts of Miss Mita Vaghi in providing her expertise in event management and her diligent support and Anete Ashton of IoP Publications for her guidance and help in producing the conference proceedings and online listing.

A scoping review about conference objectives and evaluative practices: how do we get more out of them?

PubMed

Neves, Justin; Lavis, John N; Ranson, M Kent

2012-08-02

Large multi-day conferences have often been criticized as ineffective ways to improve social outcomes and to influence policy or practice. Unfortunately, many conference evaluations have also been inadequate in determining the impact of a conference on its associated social sector, with little evidence gathered or analyzed to substantiate or refute these criticisms. The aim of this scoping review is to investigate and report stakeholders' objectives for planning or participating in large multi-day conferences and how these objectives are being evaluated. We conducted a scoping review supplemented by a small number of key informant interviews. Eight bibliographic databases were systematically searched to identify papers describing conference objectives and/or evaluations. We developed a conference evaluation framework based on theoretical models and empirical findings, which structured the descriptive synthesis of the data. We identified 3,073 potential papers for review, of which 44 were included in this study. Our evaluation framework connects five key elements in planning a conference and its evaluation (number in brackets refers to number of themes identified): conference objectives (8), purpose of evaluation (7), evaluation methods (5), indicators of success (9) and theories/models (8). Further analysis of indicators of success identified three categories of indicators with differing scopes (i.e. immediate, prospective or follow-up) as well as empirical links between the purpose of evaluations and these indicators. Conference objectives and evaluations were largely correlated with the type of conference (i.e. academic, political/governmental or business) but diverse overall. While much can be done to improve the quality and usefulness of conference evaluations, there are innovative assessments that are currently being utilized by some conferences and warrant further investigation. This review provides conference evaluators and organizers a simple resource to improve their own assessments by highlighting and categorizing potential objectives and evaluation strategies.

Structure and function of echinoderm telomerase RNA

PubMed Central

Podlevsky, Joshua D.; Li, Yang; Chen, Julian J.-L.

2016-01-01

Telomerase is a ribonucleoprotein (RNP) enzyme that requires an integral telomerase RNA (TR) subunit, in addition to the catalytic telomerase reverse transcriptase (TERT), for enzymatic function. The secondary structures of TRs from the three major groups of species, ciliates, fungi, and vertebrates, have been studied extensively and demonstrate dramatic diversity. Herein, we report the first comprehensive secondary structure of TR from echinoderms—marine invertebrates closely related to vertebrates—determined by phylogenetic comparative analysis of 16 TR sequences from three separate echinoderm classes. Similar to vertebrate TR, echinoderm TR contains the highly conserved template/pseudoknot and H/ACA domains. However, echinoderm TR lacks the ancestral CR4/5 structural domain found throughout vertebrate and fungal TRs. Instead, echinoderm TR contains a distinct simple helical region, termed eCR4/5, that is functionally equivalent to the CR4/5 domain. The urchin and brittle star eCR4/5 domains bind specifically to their respective TERT proteins and stimulate telomerase activity. Distinct from vertebrate telomerase, the echinoderm TR template/pseudoknot domain with the TERT protein is sufficient to reconstitute significant telomerase activity. This gain-of-function of the echinoderm template/pseudoknot domain for conferring telomerase activity presumably facilitated the rapid structural evolution of the eCR4/5 domain throughout the echinoderm lineage. Additionally, echinoderm TR utilizes the template-adjacent P1.1 helix as a physical template boundary element to prevent nontelomeric DNA synthesis, a mechanism used by ciliate and fungal TRs. Thus, the chimeric and eccentric structural features of echinoderm TR provide unparalleled insights into the rapid evolution of telomerase RNP structure and function. PMID:26598712

The 12th International Conference on Substorms (ICS-12) was held at the Ise-Shima Royal Hotel in Shima, Japan, on November 10-14, 2014. There were 125 attendees including 68 from foreign countries. The ICS has been held every 2 years since 1992 to discuss substorms, which are fundamental global-scale disturbances in the Earth's magnetosphere. The year 2014 marked the 50th anniversary of the first publication about substorms (Akasofu 1964). The conference included three tutorial lecturers (Profs. S.-I. Akasofu, V. Angelopoulous, and D. Baker), as well as many international scientists, to discuss substorm processes in the tail, their Interactions with the inner magnetosphere and the ionosphere, substorm currents and their dynamics and energetics, the role of MagnetoHydroDynamics (MHD) and kinetic instabilities, storm-substorm relationships, ULFELFVLF waves, and non-Earth substorm-like features. Prof. Akasofu also gave an evening talk about the history of auroral research since the nineteenth century with photographs that inspired and intrigued the young scientists and students in attendance.

The Boundary Integral Equation Method for Porous Media Flow

NASA Astrophysics Data System (ADS)

Anderson, Mary P.

Just as groundwater hydrologists are breathing sighs of relief after the exertions of learning the finite element method, a new technique has reared its nodes—the boundary integral equation method (BIEM) or the boundary equation method (BEM), as it is sometimes called. As Liggett and Liu put it in the preface to The Boundary Integral Equation Method for Porous Media Flow, “Lately, the Boundary Integral Equation Method (BIEM) has emerged as a contender in the computation Derby.” In fact, in July 1984, the 6th International Conference on Boundary Element Methods in Engineering will be held aboard the Queen Elizabeth II, en route from Southampton to New York. These conferences are sponsored by the Department of Civil Engineering at Southampton College (UK), whose members are proponents of BIEM. The conferences have featured papers on applications of BIEM to all aspects of engineering, including flow through porous media. Published proceedings are available, as are textbooks on application of BIEM to engineering problems. There is even a 10-minute film on the subject.

PREFACE: 13th International Conference on Liquid and Amorphous Metals

NASA Astrophysics Data System (ADS)

Popel, Pjotr; Gelchinskii, Boris; Sidorov, Valeriy; Son, Leonid; Sabirzjanov, Alexandre

2007-06-01

The state of the art in the field of liquid and amorphous metals and alloys is regularly updated through two series of complementary international conferences, the LAM (Liquid and Amorphous Metals) and the RQ (Rapidly Quenched Materials). The first series of the conferences started as LM-1 in 1966 at Brookhaven for the basic understanding of liquid metals. The subsequent LM conferences were held in Tokyo (1972) and Bristol (1976). The conference was renewed in Grenoble (1980) as a LAM conference including amorphous metals and continued in Los Angeles (1983), Garmisch-Partenkirchen (1986), Kyoto (1989), Vienna (1992), Chicago (1995), Dortmund (1998), Yokohama (2001) and Metz (2004). The conferences are mainly devoted to liquid and amorphous metals and alloys. However, communications on some non-metallic systems such as semi conductors, quasicrystals etc, were accepted as well. The conference tradition strongly encourages the participation of junior researchers and graduate students. The 13th conference of the LAM series was organized in Ekaterinburg, Russia, by the Institute of Metallurgy of the Ural Branch of the Russian Academy of Sciences (IMet UB RAS) and Ural State Pedagogical University (USPU) and held on 8-13 July 2007 under the chairmanship of Professors Pjotr Popel (USPU) and Boris Gelchinskii (IMet UB RAS). There were 242 active and about 60 guest participants from 20 countries who attended the conference. There were no parallel sessions and all oral reports were separated into three groups: invited talks (40 min), full-scale (25 min) and brief (15 min) oral reports. The program included 10 sessions, ranging from purely theoretical subjects to technological application of molten and amorphous alloys. The following sessions took place: A) Electronic structure and transport, magnetic properties; B) Phase transitions; C) Structure; D) Atomic dynamics and transport; E) Thermodynamics; F) Modelling, simulation; G) Surface and interface; H) Mechanical properties and new materials; I) Quasicrystals; J) Industrial applications. The most representative sessions were E (53 reports), C (47), D (43) and F (40). All posters were exhibited during the first (sections A-E) or the last (sections F-J) three days of the conference. All the sessions took place in the Government House of Sverdlovsk Region where, in addition, everyone was able to enjoy dishes of Russian cuisine during lunches and coffee breaks. As usual, each oral session started from an invited talk. Therefore, 10 invited lecturers presented their reports. In accordance with contemporary tendency the first invited talk of M Yao (Kyoto University) was devoted to interrelations between liquid metal studies and nano-science. He pointed out that physics of disordered matter, especially liquid metals, has provided nano-science with basic ideas and theoretical tools such as ab initio MD simulation. K Tamura (Kyoto University) reported results of experimental investigation of expanded liquid rubidium showing that observed structural features originate from the instability of the low-density electron gas. Modern theory has predicted that interacting electron gas suffers a negative compressibility and the static dielectric-function (DF) becomes negative when electron density is sufficiently reduced. The negative DF is of special interest in connection with the possibility of a new type of superconductor. In the invited lecture of M I Mendelev and J R Morris (USA) MD simulations were performed to study phase transformations in supercooled liquid Al. The authors found that widely used EAM potential for Al provides vitrification for the cooling rates achievable in classical MD simulation, while other Al potentials provide crystallization under the same conditions. The reason for this difference, as well as features of the vitrification in the EA Al, were discussed. P Häussler (Chemnitz University) spoke about fundamental structure-forming processes in liquid and amorphous materials. He had proposed the resonance model as an autonomous missing link between the microscopic description of atoms/molecules, described by Schrödinger's equation, and the crystals where global concepts as planar resonances exist and Bloch's theorem is applied. D Holland-Moritz (Institut für Materialphysik, Köln) presented results of the first quasielastic neutron scattering experiments on electromagnetically levitated metallic melts. The studies are indicative of Arrhenius behaviour of the diffusion constants in the whole investigated temperature regime ranging from temperatures above the melting temperature up to the metastable regime of an undercooled liquid. L Son (USPU) discussed the existing analytical theories of liquid-liquid phase transitions that have been supposed for a wide variety of liquids, but are rather poorly understood analytically. The application of these theories to liquid metal systems was also demonstrated. An approach to study dynamics and kinetics of cavitation in stretched liquid metals by the classical molecular dynamics (MD) method was presented in the talk of G E Norman (Institute for High Temperatures, Moscow). Both quantitative and qualitative disagreements with the classic theory of homogeneous nucleation were found. Analytic extentions of MD results beyond the space and temporal limits accessible for the MD method were discussed also. G Wilde (University of Münster) spoke about experimental investigation of the impact of interface properties and, more specifically, of the interface morphology in matrix-encased metallic nanoparticles on macroscopic properties, such as melting transition by a combination of microscopic, microanalytical and calorimetric measurements. These results are discussed with respect to the underlying mechanisms that leads to size dependent phase equilibria. In the invited talk of V Keryvin (University of Rennes) the indentation ability was proposed to be used as a probe for pressure-sensitivity in metallic glasses. The main conclusion was: the indentation test provides good means to study the elasto-plastic behaviour of these materials as well as a relevant tool to subject them to multiaxial loadings. The influence of changes in local ordering of precursor melt on the formation of amorphous state and subsequent crystallization was a subject of a report presented by P Švec (Institute of Physics, Bratislava). The effect was shown for rapidly quenched Fe-Mo-B system with addition of Cu and substitution of Fe by Co prepared under varying conditions of planar flow casting and using master alloys with specific melt treatment. About 320 abstracts were received and 180 manuscripts were finally submitted for publication. All the papers followed invited lectures and full-scale oral reports were sent to the Journal of Physics: Condensed Matter for publication in a special issue. These papers will be published according to the current standard practices, policies and procedures of the Journal. All the papers following brief oral reports and posters were collected for this volume of Journal of Physics: Conference Series. All of them were edited by editors from Ekaterinburg. The Journal will provide access to all of the accepted papers free of charge via its web server. Afterwards, to publish and ship hardcopies of both the journals (Journal of Physics: Condensed Matter and Journal of Physics: Conference Series) and CDs containing all Conference papers. It was decided during the joint meeting of both the International Advisory Board and International Program Committee that the next conference in the LAM series, LAM14, will be arranged by the groups of A Di Cicco, Camerino University, and T Scopigno, University Roma `La Sapienza', in Rome, Italy. It is not an easy task to comment on new scientific tendencies in the field of liquid and amorphous alloys just after the conference. It takes one or two years to estimate the significance of the event. Only one conclusion is obvious: the LAM13 Conference had opened a door between the world scientific community and Russian scientists who have high expertise in the field but could not actively participate in the conferences of the LAM series before because of the situation in Russian economics. We are thankful to the Advisory and Program Committees of previous LAM12 conference in Metz and especially to Dr Monique Calvo-Dahlborg for their trust and the opportunity to manage such an outstanding event in Russia. In addition we would like to give all our sincere thanks to:

This cross-disciplinary emphasis was reflected in keynote talks by Dr Wayne Brown, President and founder of Dynalloy, Inc., 'Cross-Discipline Sharing'; Dr Brad Allenby, Arizona State University, 'You Want the Future? You can't Handle the Future!'; and Professor Aditi Chattopadhyay, Arizona State University, 'A Multidisciplinary Approach to Structural Health Monitoring and Prognosis'. SMASIS continues to grow our community through both social and technical interchange. The conference location, the exotic Firesky Resort and Spa, exemplified the theme of our Guest Symposium on Sustainability, being the only Green Seal certified resort in Arizona, and highlighting four elements thought to represent all that exist: fire, water, earth and air. Several special events were held around this theme including the night at the oasis reception sponsored by General Motors, sustainability bingo, smart trivia and student networking lunches, and an Arizona pow-wow with a spectacular Indian hoop dance. Our student and young professional development continues to grow strong with best paper and hardware competitions, scavenger student outing and games night. We are very proud that our students and young professionals are always seeking out ways to give back to the community, including organizing outreach to local high school talent. We thank all of our sponsors who made these special events possible. We hope that these social events provided participants with the opportunity to expand their own personal community and broaden their horizons. Our ultimate goal was to provide a friendly, casual southwestern forum for the exchange of the 'hottest' ideas and latest results. Our sincere appreciation goes to all the presenters for choosing to share their very best work at this conference. SMASIS is divided into seven symposia which span basic research, applied technological design and development, and industrial and governmental integrated system and application demonstrations: SYMP 1 Multifunctional Materials; SYMP 2 Active Materials, Mechanics and Behavior; SYMP 3 Modeling, Simulation and Control; SYMP 4 Enabling Technologies and Integrated System Design; SYMP 5 Structural Health Monitoring/NDE; SYMP 6 Bio-inspired Smart Materials and Structures; and SYMP 7 Guest Symposium on Sustainability. In addition, the conference introduced a new student and young professional development symposium. Authors of papers in the materials area (symposia 1, 2 and 6) were invited to write a full journal article on their presentation topic for publication in this Special Issue of Smart Materials and Structures. This collection of papers demonstrates the exceptional quality and originality of the conference presentations. We appreciate their efforts in producing this collection of highly relevant articles on smart materials.
