AbstractThe IFFANIAM study (Impact of frailty and functional status in elderly patients with ST segment elevation myocardial infarction undergoing primary angioplasty) is an observational multicenter registry to assess the impact of frailty and functional status on outcomes of elderly patients with ST‐segment elevation myocardial infarction (STEMI) undergoing primary angioplasty. STEMI patients age 75 years or older undergoing primary angioplasty will be extensively studied during admission in 4 tertiary care Hospitals in Spain, assessing their baseline functional status (Barthel index, Lawton‐Brody index), frailty (Fried criteria, FRAIL scale [fatigue, resistance, ambulation, illnesses, and loss of weight]), comorbidities (Charlson index), nutritional status (Mini Nutritional Assessment–Short Form), and quality of life (Seattle Angina Questionnaire). Participants will be managed according current recommendations. The primary outcome will be the description of 1‐year mortality, its causes, and associated factors. Secondary outcomes will be functional capacity and quality of life. Results will help to better understand the impact of frailty and functional ability on outcomes in elderly STEMI patients undergoing primary angioplasty, thus potentially contributing to improving their clinical management. Higher life expectancy has resulted in a large segment of elderly population and an increase in myocardial infarction in these patients. This calls attention to healthcare systems to focus on promoting methods to improve the clinical management of this population.
Simultaneous Improvement in Structural Properties and Microwave Shielding of Polymer Blends with Carbon Nanotubes

Published: October 2015

AbstractPrecise control in dispersing nanostructured materials in a polymer blend structure is a key requirement in designing materials with tailor‐made properties. In this study, the dispersion of a conducting additive (multiwalled carbon nanotubes, MWNTs) in a co‐continuous polymer blend structure was controlled by introducing surface‐active groups, which react in situ and localize in the thermodynamically nonpreferred phase. In addition, by modifying the MWNTs with a macromolecule, which is mutually miscible with the entities, the nanoscopic particles can be localized at the interface. This way, different MWNTs can be positioned in different phases under macroscopic processing conditions. Herein, we report that this unique strategy has led to simultaneous enhancement in both mechanical strength and electrical conductivity of the blend nanocomposites. In addition, intriguingly, the microwave shielding efficiency can also be tuned by this ordered arrangement of MWNTs in the blend structure in striking contrast to when the MWNTs are in the thermodynamically favored phase. An outstanding two‐fold enhancement in the Young′s modulus, as compared to control blends, and an impressive bulk electrical conductivity of 1 S m−1 was noted for a particular blend structure wherein different MWNTs were positioned in different phases. In addition, the best blend structure designed here also exhibited a minimum reflection loss (RL) of approximately −61 dB and a shielding effectiveness of >30 dB at 18 GHz. These data uncover the importance of polymer blends in designing lightweight electromagnetic interference (EMI) shielding materials.
multimark: an R package for analysis of capture–recapture data consisting of multiple “noninvasive” marks
Authors: McClintock Brett T. 
Published: October 2015

AbstractI describe an open‐source R package, multimark, for estimation of survival and abundance from capture–mark–recapture data consisting of multiple “noninvasive” marks. Noninvasive marks include natural pelt or skin patterns, scars, and genetic markers that enable individual identification in lieu of physical capture. multimark provides a means for combining and jointly analyzing encounter histories from multiple noninvasive sources that otherwise cannot be reliably matched (e.g., left‐ and right‐sided photographs of bilaterally asymmetrical individuals). The package is currently capable of fitting open population Cormack–Jolly–Seber (CJS) and closed population abundance models with up to two mark types using Bayesian Markov chain Monte Carlo (MCMC) methods. multimark can also be used for Bayesian analyses of conventional capture–recapture data consisting of a single‐mark type. Some package features include (1) general model specification using formulas already familiar to most R users, (2) ability to include temporal, behavioral, age, cohort, and individual heterogeneity effects in detection and survival probabilities, (3) improved MCMC algorithm that is computationally faster and more efficient than previously proposed methods, (4) Bayesian multimodel inference using reversible jump MCMC, and (5) data simulation capabilities for power analyses and assessing model performance. I demonstrate use of multimark using left‐ and right‐sided encounter histories for bobcats (Lynx rufus) collected from remote single‐camera stations in southern California. In this example, there is evidence of a behavioral effect (i.e., trap “happy” response) that is otherwise indiscernible using conventional single‐sided analyses. The package will be most useful to ecologists seeking stronger inferences by combining different sources of mark–recapture data that are difficult (or impossible) to reliably reconcile, particularly with the sparse datasets typical of rare or elusive species for which noninvasive sampling techniques are most commonly employed. Addressing deficiencies in currently available software, multimark also provides a user‐friendly interface for performing Bayesian multimodel inference using capture–recapture data consisting of a single conventional mark or multiple noninvasive marks.
Determination of daily eco‐hydrographs by the fish spawning habitat suitability model and application to reservoir eco‐operation

Published: October 2015

AbstractGlobal conflict over water has become increasingly problematic. To meet water demands for economic growth in China, a large number of hydro‐projects have been developed and operated, which have significantly altered the natural hydrological regime of many rivers and imposed profound impact on aquatic ecosystems. Conservation of appropriate ecological flow is essential to balance river ecosystem health and economic development. We proposed an innovative method for river eco‐hydrograph determination based on the protection of fish spawning habitat. An integrated hydro‐environmental‐habitat model was developed and applied in de‐watered channels in the middle of Yalong River, China, where water was diverted for hydropower generation.Schizothorax chongi(S. chongi), the dominant and commercial indigenous fish, was selected as the target species. Different from previous research, the impacts of fragmentation and water level variation on fish habitat were analysed in the spawning period. Eco‐hydrographs for different preservation levels ofS. chongispawning habitat were estimated using the developed model, and the suitable one was recommended. Compared with traditional hydrologic and hydraulic methods, the improved habitat method not only determined the ecological water demand of the species more meaningfully but also increased water use efficiency.

Optimal memoryless regulator of large‐scale systems with time delays in the interconnections and the states via decentralized control
Authors: Matsuki Tsuyoshi , Kubo Tomohiro 
Published: October 2015

AbstractA method to construct optimal memoryless regulators of large‐scale systems with time delays in the interconnections and the states is proposed. Each feedback gain of decentralized control laws is obtained directly from solutions of simultaneous linear matrix inequalities. First, a sufficient condition for the stability of the overall closed‐ loop system is presented. Then it is extended so that the overall system and each subsystem remain stable, even if all or some of the interconnections between subsystems are cut. Lastly, a simplification of the implementation is discussed in the perspective of feedback loop reduction. © 2011 Wiley Periodicals, Inc.

Modeling of magnetization curves in nonoriented electrical steel sheets
Authors: Kaido Chikara 
Published: October 2015

AbstractThis paper discusses the modeling of magnetization curves in nonoriented electrical steel sheets. The initial curve and hysteresis loop below 0.15 T are approximately modeled by the Rayleigh model, and the Rayleigh loop constants are nearly proportional to the crystalline grain size. Hysteresis loops above 0.15 T in the magnetization rotation region are represented by the Preisach model, with consideration of the grain size distribution and the RD easy axis. Magnetization curves above 10 kA/m are calculated by the magnetization rotation model. However, magnetization curve modeling is necessary between the domain displacement model and the magnetization rotation regions. Magnetization curves in this region are modeled considering the field component ${B^N}$, where B is the flux density and N is the order of the flux density and is equal to about 15. © 2012 Wiley Periodicals, Inc.

Protein adsorption onto nanoparticles induces conformational changes: Particle size dependency, kinetics, and mechanisms
Authors: Satzer Peter , Svec Frantisek , Sekot Gerhard , Jungbauer Alois 
Published: October 2015

The use of nanomaterials in bioapplications demands a detailed understanding of protein–nanoparticle interactions. Proteins can undergo conformational changes while adsorbing onto nanoparticles, but studies on the impact of particle size on conformational changes are scarce. We have shown that conformational changes happening upon adsorption of myoglobin and BSA are dependent on the size of the nanoparticle they are adsorbing to. Out of eight initially investigated model proteins, two (BSA and myoglobin) showed conformational changes, and in both cases this conformational change was dependent on the size of the nanoparticle. Nanoparticle sizes ranged from 30 to 1000 nm and, in contrast to previous studies, we attempted to use a continuous progression of sizes in the range found in live viruses, which is an interesting size of nanoparticles for the potential use as drug delivery vehicles. Conformational changes were only visible for particles of 200 nm and bigger. Using an optimized circular dichroism protocol allowed us to follow this conformational change with regard to the nanoparticle size and, thanks to the excellent temporal resolution also in time. We uncovered significant differences between the unfolding kinetics of myoglobin and BSA. In this study, we also evaluated the plausibility of commonly used explanations for the phenomenon of nanoparticle size‐dependent conformational change. Currently proposed mechanisms are mostly based on studies done with relatively small particles, and fall short in explaining the behavior seen in our studies.
Deterioration of a fractured carbonate caprock exposed to CO2‐acidified brine flow

AbstractA flow‐through experiment was performed to investigate evolution of a fractured carbonate caprock during flow of CO2‐acidified brine. A core was taken from the Amherstburg limestone, a caprock formation overlying the Bois Blanc and Bass Islands formations, which have been used to demonstrate CO2 storage in the Michigan basin. The inlet brine was representative of deep saline brines saturated with CO2, resulting in a starting pH of 4.4. Experimental conditions were 27 °C and 10 MPa. X‐ray computed tomography and scanning electron microscopy were used to observe evolution of fracture geometry and to investigate mineralogical changes along the fracture surface. The initial brine flow corresponded to an average fluid velocity of 110 cm hr−1. After one week, substantial mineral dissolution caused the average cross‐sectional area of the fracture to increase from 0.09 cm2 to 0.24 cm2. This demonstrates that carbonate caprocks, if fractured, can erode quickly and may jeopardize sealing integrity when hydrodynamic conditions promote flow of CO2‐acidified brine. However, changes to fracture permeability due to mineral dissolution may be offset by unaltered constrictions along the flow path and by increases in surface roughness. In this experiment, preferential dissolution of calcite over dolomite led to uneven erosion of the fracture surface and an increase in roughness. In areas with clay minerals, calcite dissolution left behind a silicate mineral‐rich microporous coating along the fracture wall. Thus, the evolution of fracture permeability will depend in a complex way on the carbonate content, as well as the heterogeneity of the minerals and their spatial patterning. © 2011 Society of Chemical Industry and John Wiley & Sons, Ltd

AbstractBackgroundSignal transducer and activator 1 (STAT‐1) mutations are rare and have been implicated in combined immunodeficiency, enhanced tumorigenesis, and vascular defects.MethodsA 60‐year‐old woman with a novel STAT‐1 mutation and resulting immunodeficiency, squamous cell carcinoma, and vascular disease presented with profuse epistaxis secondary to rupture of an aberrant artery that she developed in part because of this mutation. After unsuccessful posterior packing, embolization was initiated but subsequently aborted because of a bovine origin carotid artery and a history of multiple carotid dissections.ResultsAfter repeat posterior packing, hemostasis was achieved. No additional episodes of epistaxis occurred in the subsequent 13 months.ConclusionVascular anomalies can present challenges in epistaxis management. In patients with conditions known to cause vascular anomalies, it is critical to obtain vascular imaging before intervention. © 2015 Wiley Periodicals, Inc. Head Neck 38: E68–E70, 2016

AbstractA putative acid metabolite of a novel highly effective antiparkinsonian agent, (4S,5R,6R)‐5,6‐dihydroxy‐4‐(prop‐1‐en‐2‐yl)cyclohex‐1‐ene‐1‐carboxylic acid (5), was synthesized for the first time. Several synthetic approaches based on different transformations of O‐bearing monoterpenoids of the pinane and p‐menthane series were developed and tested in the course of the study. Acid 5 was synthesized starting from a commercially available monoterpenoid, (−)‐verbenone, in a total yield of 4.4% over eight steps.
Acculturation and Individualism as Predictors of Work‐Family Conflict in a Diverse Workforce

Published: October 2015

AbstractEthnic and cultural diversity is an increasing reality in the US workplace. The current study highlights the importance of acknowledging the culturally heterogeneous nature of ethnic groups, and the need to focus on social identity characteristics such as cultural values when assessing group differences. We demonstrate that cultural values (i.e., individualism) contribute to employees' experiences of work‐family conflict beyond the effects of ethnicity. Specifically, we introduce a model informed by social identity theory that explains why acculturation is related to work‐family conflict. The model was tested with a sample of 309 employed Caucasian and Hispanic Americans. An empirical test of our model provides evidence that individualism mediates the relationship between language‐ and social‐based acculturation and work‐family conflict, even when controlling for ethnicity. Additionally, alternative models further reveal that the effects of acculturation and individualism contribute to work interfering with family. As an implication of the current study, we suggest that researchers and organizational managers should consider the cultural values of their diverse workforce when implementing policies that affect conflict between work and family. © 2013 Wiley Periodicals, Inc.
FLOOD INUNDATION ANALYSIS USING A DISTRIBUTED TANK MODEL FOR A FLAT, LOW‐LYING AGRICULTURAL AREA UNDERGOING URBANIZATION IN HANOI, VIETNAM

Published: October 2015

ABSTRACTIn the 2000s, urbanization has extended to approximately 30% of the total upstream area of the Song Nhue Hydraulic Structure Scheme (HSS) in Hanoi, Vietnam, and the Song Nhue HSS area is predicted to become completely urbanized by 2030. In this study, flood inundation analyses were carried out for the upstream area of the Song Nhue HSS. The analyses were conducted using a horizontally distributed continuous tank model. First, the distributed tank model was constructed on the basis of the hydraulic dimensions of rivers, irrigation and drainage canals, gates, and pumping stations, as well as information about land use and the drainage network. Then, six observed flood events with return periods of 2, 3, 5, 10, 30, and 100 years were selected from past records and simulated using the model. The comparison between the simulated and the observed upstream water levels in the outlets indicated that the developed model could accurately estimate variations in water levels. Second, a scenario analysis based on predictions of urban growth was conducted using the distributed tank model. The scenario analysis suggests necessary and effective measures that can be taken to prevent flood inundation in the targeted area. Copyright © 2013 John Wiley & Sons, Ltd.
8.4.1 Fundamentals of Agile Systems Engineering – Part 1
Authors: Dove Rick , LaBarge Ralph 
Published: October 2015

AbstractAgile systems‐engineering and agile‐systems engineering are two different concepts that share the word agile. In the first case the system of interest is an engineering process, and in the second case the system of interest is what is produced by an engineering process. The word agile refers to the adaptability and the sustainment of adaptability in both types of systems. Sustained adaptability is enabled by an architectural pattern and a set of system design principles that are fundamental and common to both types of systems. Research that identified this architectural pattern and design principles is reported, updated, and applied here in two Parts. Part 1 focuses on agile‐systems engineering, reviewing the origins, values, and core concepts that define and enable domain independent agility in any type of system. Part 2 focuses on agile systems‐engineering, identifying core agility‐enabling concepts in the software‐development domain‐specific practice known as Scrum, reviewing an agile hardware/software satellite‐development systems‐engineering case for its source of agility, and then suggesting the development of an agile systems‐engineering life cycle model as a natural next step.
Behavior of bone cells in contact with magnesium implant material
Authors: Burmester Anna , Willumeit‐Römer Regine , Feyerabend Frank 
Published: October 2015

AbstractMagnesium‐based implants exhibit several advantages, such as biodegradability and possible osteoinductive properties. Whether the degradation may induce cell type‐specific changes in metabolism still remains unclear. To examine the osteoinductivity mechanisms, the reaction of bone‐derived cells (MG63, U2OS, SaoS2, and primary human osteoblasts (OB)) to magnesium (Mg) was determined. Mg‐based extracts were used to mimic more realistic Mg degradation conditions. Moreover, the influence of cells having direct contact with the degrading Mg metal was investigated. In exposure to extracts and in direct contact, the cells decreased pH and osmolality due to metabolic activity. Proliferating cells showed no significant reaction to extracts, whereas differentiating cells were negatively influenced. In contrast to extract exposure, where cell size increased, in direct contact to magnesium, cell size was stable or even decreased. The amount of focal adhesions decreased over time on all materials. Genes involved in bone formation were significantly upregulated, especially for primary human osteoblasts. Some osteoinductive indicators were observed for OB: (i) an increased cell count after extract addition indicated a higher proliferation potential; (ii) increased cell sizes after extract supplementation in combination with augmented adhesion behavior of these cells suggest an early switch to differentiation; and (iii) bone‐inducing gene expression patterns were determined for all analyzed conditions. The results from the cell lines were inhomogeneous and showed no specific stimulus of Mg. The comparison of the different cell types showed that primary cells of the investigated tissue should be used as an in vitro model if Mg is analyzed. © 2015 Wiley Periodicals, Inc.

Published: October 2015

AbstractThe wetting characteristics of self‐assembled monolayers (SAMs) on three different surface structures of thin film, microcone array, and nanowire forest topologies, which were chemically modified using phosphonic acid (HDF‐PA and OD‐PA) and trichlorosilane (HDF‐S), were investigated. The molecular SAM‐coated nanowire forest structures exhibited superhydrophobic properties with contact angles of 150.6°–155.4°, compared with the other structures combined with OD‐PA, HDF‐PA, and HDF‐S SAMs, which displayed contact angles of 99.5°–116.8°. Moreover, the HDF‐PA and HDF‐S SAM‐coated nanowire forest structures showed omniphobic properties for both flat and curved surfaces, irrespective of the substrate form. Four liquid droplets of different viscosities and composition (water, urea solution, oil, and photoresist) slid on the HDF‐PA and HDF‐S SAM‐coated nanowire forest surfaces without leaving any traces. The omniphobic properties of the molecular SAM‐coated nanowire forest structures developed in this study could be used for various applications in which their slippery effect is desirable, such as in medical tubes and the interior of pipes. © 2015 Wiley Periodicals, Inc.
