Stabilization Criteria for Singular Fuzzy Systems With Random Delay and Mixed Actuator Failures
Authors: Rathinasamy Sakthivel , Rathika M. , Kaviarasan B. , Shen Hao 
Published: July 2017

AbstractThe problem of reliable sampled‐data control design for uncertain singular fuzzy system with randomly occurring delay and nonlinear actuator failures is studied in this paper. The fault model is composed of two parts in which, linear part stands for the gain missing of actuators that vary with the true control input linearly, while the nonlinear part indicates some bounded nonlinear variation. Moreover, the time delay which encountering in the proposed controller is assumed to be randomly varying and satisfies Bernoulli distributed probabilities. By constructing a proper time‐dependent Lyapunov functional, some novel sufficient conditions are derived in terms of linear matrix inequalities (LMIs) for the existence of robustly stochastically stabilizing reliable sampled‐data controllers. Two simulation examples are given to demonstrate the effectiveness of the proposed method.
Die‐by Framing both Lengthens and Shortens Life: Further Evidence on Constructed Beliefs in Life Expectancy
Authors: Comerford David A. , Robinson Jenny 
Published: July 2017

AbstractDecisions regarding consumption over the lifespan require some estimate of how long that lifespan is likely to be. Payne et al. (2013) found that respondents' estimates of their own life expectancy are on average 8.6 years shorter when elicited using a die‐by frame than when elicited by a live‐to frame. If decision makers act on these life expectancies, then an arbitrary detail of framing will lead to drastically different choices. We propose that the framing effect is sensitive to the iterative probabilistic elicitation procedure employed by the previous literature. Study 1 compares the framing effect across the iterative probabilistic procedure and a point estimate procedure that simply asks respondents the age they will live to/die by. The iterative probabilistic procedure implies a life expectancy six years shorter in the die‐by frame than in the live‐to frame, replicating the results of Payne et al. (2013). With the point estimate procedure, however, the framing effect reverses: the die‐by frame increases life expectancy by three years. In Study 2, we test for the framing effect using a point estimate procedure on a representative sample of 2000 Britons. Again, and in contrast with the previous literature, we find that the die‐by frame implies longer life. Our results reinforce the previous literature that beliefs around life expectancy are constructed. We recommend caution when attempting to debias life expectancy estimates or using life expectancies in choice architecture. Copyright © 2017 John Wiley & Sons, Ltd.

Trends of Alkane Activation on Doped Cobalt (II, III) Oxide from First Principles
Authors: Fung Victor , Tao Franklin (Feng) , Jiang De‐en 
Published: July 2017

AbstractThe surface doping of a metal oxide can tune its catalytic performance, but it remains unclear how the tuning depends on the dopant type and the surface facet. Herein we study doped Co3O4 (1 1 1) and (3 1 1) surface facets using first‐principles density functional theory (DFT) to obtain general descriptors for oxygen reactivity (which include vacancy formation energy and hydrogen adsorption energy) and correlate them to ethane C−H activation energy as a measure of the catalytic performance. The periodic trends of the dopants are investigated for a total of 20 dopants, namely, the elements from K to Ge. We find strong linear correlations between the oxygen reactivity descriptors and the computed energy barriers. We also discover a strong surface facet sensitivity among certain dopants such that different surface orientations and sites lead to different or even the opposite dopant performance. This work provides a useful guide for dopant performance in ethane activation on the two very different Co3O4 surfaces.
Targeted Delivery of a Mannose‐Conjugated BODIPY Photosensitizer by Nanomicelles for Photodynamic Breast Cancer Therapy

Published: July 2017

AbstractThe targeted delivery of a photosensitizer (PS) with appropriate carriers represents an attractive means of selectively delivering cargo to target tissues or subcellular compartments for photodynamic therapy (PDT). Herein, a three‐arm distyryl BODIPY derivative conjugated with mannose units (denoted by BTM) that can co‐assemble with Tween 80 to form nanomicelles (BTM‐NMs) for targeted PDT is reported. MDA‐MB‐231 breast cancer cells recognized and specifically internalized BTM‐NMs via mannose‐receptor‐mediated endocytosis with preferential accumulation in the lysosomes. These NMs could disassemble in cell lysosomes and subsequently induce highly efficient singlet oxygen (1O2) generation upon light irradiation. 1O2 disrupted the lysosomal membrane and promoted the escape of BTM from the lysosome into the cytoplasm, thereby resulting in the efficient and selective killing of cancer cells through PDT. This study may provide a new strategy for designing targeted PDT systems to fight cancer.

Published: July 2017

AbstractThe incorporation of fluorinated moieties into organic structures is a particularly powerful approach for generating compounds with useful biological applications in industry, pharmacology, and agriculture. Here, the recently developed reagent—CF2HCHN2—selectively esterifies carboxyl groups on organic molecules in the presence of other polar functional groups. The reaction is remarkably simple, proceeding at room temperature in chloroform without addition of a catalyst. The procedure allows “last‐step” incorporation of a fluorinated ester moiety into organic structures, including bioorganic molecules such as peptides and proteins. The fluorinated ester can subsequently function as a 19F‐probe in biomolecules, thereby enabling molecular size determination by diffusion 19F NMR experiments.

BACKGROUNDScreening over many years is required to optimize reductions in colorectal cancer (CRC) mortality. However, no prior trials have compared strategies for obtaining long‐term adherence.METHODSSystems of Support to Increase Colorectal Cancer Screening and Follow‐Up was implemented in an integrated health care organization in Washington State. Between 2008 and 2009, 4675 individuals aged 50 to 74 years were randomized to receive the usual care (UC), which included clinic‐based strategies to increase CRC screening (arm 1), or, in years 1 and 2, mailings with a call‐in number for colonoscopy and mailed fecal tests (arm 2), mailings plus brief telephone assistance (arm 3), or mailings and assistance plus nurse navigation (arm 4). Active‐intervention subjects (those in arms 2, 3, and 4 combined) who were still eligible for CRC screening were randomized to mailings being stopped or continued in years 3 and 5. The time in compliance with CRC screening over 5 years was compared for persons assigned to any intervention and persons assigned to UC. Screening tests contributed time on the basis of national guidelines for screening intervals (fecal tests annually, sigmoidoscopy every 5 years, and colonoscopy every 10 years).RESULTSAll participants contributed data, but they were censored at disenrollment, death, the age of 76 years, or a diagnosis of CRC. Compared with UC participants, intervention participants had 31% more adjusted covered time over 5 years (incidence rate ratio, 1.31; 95% confidence interval, 1.25‐1.37; covered time, 47.5% vs 62.1%). Fecal testing accounted for almost all additional covered time.CONCLUSIONSIn a health care organization with clinic‐based activities to increase CRC screening, a centralized program led to increased CRC screening adherence over 5 years. Longer term data on screening adherence and its impact on CRC outcomes are needed. Cancer 2017;123:4472‐80. © 2017 American Cancer Society.
A Novel Two‐Step Ammonia‐Free Atomic Layer Deposition Approach for Boron Nitride
Authors: Hao Wenjun , Marichy Catherine , Journet Catherine , Brioude Arnaud 
Published: July 2017

AbstractDue to their high potential in energy and environment domains, synthetic approach allowing fabrication of high quality boron nitride (BN) structures in a controlled manner is of great interest. Herein, a two‐step ammonia‐free atomic layer deposition approach to BN, based on polymer‐derived‐ceramics chemistry, is reported for the first time. Using trichloroborazine and hexamethyldisilazane as precursors, a conformal pre‐ceramic polymer layer is grown at low temperature, 80 °C, and then converted into dense hexagonal BN (h‐BN). The present approach allows conformal and homogeneous deposition of h‐BN films on various substrates with a thickness control at the atomic scale. It proves to be successful for fabricating various tuned BN nanostructures and composites that are efficient in water purification. In particular, the obtained nanostructures demonstrate high hydrophobicity and they are investigated as water filters for organic/water separation. Good separation efficiency is demonstrated that highlights the high potential of such atomic layer deposition (ALD) structures in water treatment.

Published: July 2017

AbstractIn this research, the three‐dimensional structural and colorimetric modeling of three‐dimensional woven fabrics was conducted for accurate color predictions. One‐hundred forty single‐ and double‐layered woven samples in a wide range of colors were produced. With the consideration of their three‐dimensional structural parameters, three‐dimensional color prediction models,K/S‐,R‐, andL*a*b*‐based models, were developed through the optimization of previous two‐dimensional models which have been reported to be the three most accurate models for single‐layered woven structures. The accuracy of the new three‐dimensional models was evaluated by calculating the color differences ΔL*, ΔC*, Δh°, and ΔECMC(2:1)between the measured and the predicted colors of the samples, and then the error values were compared to those of the two‐dimensional models. As a result, there has been an overall improvement in color predictions of all models with a decrease in ΔECMC(2:1)from 10.30 to 5.25 units on average after the three‐dimensional modeling.
A novel collective matrix factorization model for recommendation with fine‐grained social trust prediction
Authors: Wang Jinkun , Zhang Shasha , Liu Xiao , Jiang Yuanchun , Zhang Min 
Published: July 2017

SummaryRecommender systems are playing an increasing role in improving user satisfaction as they can recommend items which might be highly interested to users. Recent advances have proven that social relations such as trust and distrust relations among users are helpful in improving recommendation accuracy. Traditional social recommendation methods directly utilize unweighted trust and distrust relations into collaborative filtering framework. These methods will lose their power when the trust or distrust relation data is sparse, which significantly hinders the improvement of rating prediction accuracy. To address this problem, we transform the unweighted trust and distrust relations into fine‐grained weighted social trust matrix which is denser and encodes the trust and distrust degree for pair of users. The weighted social trust matrix is then combined with the rating matrix in a collective matrix factorization framework to implement rating prediction task. Experimental results based on Extended Epinions dataset show that the proposed collective matrix factorization model with fine‐grained weighted social trust matrix can achieve better accuracy than conventional social recommendation algorithms such as SoRec and its extensions.
An acceleration of quasigroup operations by residue arithmetic
Authors: Krömer Pavel , Platoš Jan , Nowaková Jana , Snášel Václav 
Published: July 2017

SummaryQuasigroup operations are essential for a wide range of cryptographic procedures that includes cryptographic hash functions, electronic signatures, pseudorandom number generators, and stream and block ciphers. Quasigroup cryptography achieves high levels of security at low memory and computational costs by an iterative application of quasigroup operations to streams and blocks of data. The use of large quasigroups can further improve the strength of cryptographic operations. However, the order of used quasigroups is the main factor affecting the memory requirements of quasigroup cryptographic schemes. Alternative quasigroup representations that do not store their multiplication tables in computer memory yield increased computational costs. In any case, an efficient implementation of quasigroup operations is critical for practical applications of quasigroup cryptography. Residue number systems allow a fast, concurrent realization of addition and multiplication. In this work, residue arithmetic is used to accelerate quasigroup operations, and an efficient computational approach to their implementation, designed with respect to the extended instruction sets of modern processors, is proposed.

Published: July 2017

ObjectivesThe quality of cervicovaginal smears determines the success of cytology in screening programs for cervical cancer. Bethesda 2014 revisited the adequacy criteria for atrophic smears and redefined the squamous cell count in the “unsatisfactory” category. In this study, we evaluated the smear quality of Thinprep liquid‐based cervicovaginal Papanicolaou cytology slides (TPS) that were previously deemed unsatisfactory, to determine reasons for such categorization. In addition, we attempted to establish the impact of the new adequacy criteria on the rate and management of unsatisfactory diagnosis.MethodsAbout 234 unsatisfactory TPS were examined. The reasons for unsatisfactory were noted. The number of squamous cells was recounted, as per the new Bethesda criteria, in borderline adequacy cases that showed an atrophic pattern.ResultsThe leading cause for unsatisfactory TPS was lubricating gel, followed by blood, as observed in older and younger age groups, respectively (Figure 1). Eleven borderline cases were reclassified as “satisfactory” using the new Bethesda cell count, with 27% above 60 years of age. About 82% of these borderline cases were negative for intraepithelial lesion or malignancy on repeat testing.ConclusionsThere was no difference of management or change in rate of unsatisfactory when patients above 60 were reclassified into the satisfactory category using the new Bethesda count. However, a larger study is needed to evaluate whether the new recommendation for minimum cellularity can be implemented in patients above a certain age cut‐off. The study highlights the need for improvement in collection practices and education of practitioners.

AbstractBackgroundTo evaluate whether exposure to GLP‐1 receptor agonist Liraglutide could modulate pro‐atherogenic alterations previously observed in endothelial cells obtained by women affected by gestational diabetes (GD), thus exposed in vivo to hyperglycemia, oxidative stress, and inflammation and to evaluate endothelial microvesicle (EMV) release, a new reliable biomarker of vascular stress/damage.MethodsWe studied Liraglutide effects and its plausible molecular mechanisms on monocyte cell adhesion and adhesion molecule expression and membrane exposure in control (C‐) human umbilical vein endothelial cells (HUVEC) as well as in HUVEC of women affected by GD exposed in vitro to TNF‐α. In the same model, we also investigated Liraglutide effects on EMV release.ResultsIn response to TNF‐α, endothelial monocyte adhesion and VCAM‐1 and ICAM‐1 expression and exposure on plasma membrane was greater in GD‐HUVEC than C‐HUVEC. This was the case also for EMV release. In GD‐HUVEC, Liraglutide exposure significantly reduced TNF‐α induced endothelial monocyte adhesion as well as VCAM‐1 and ICAM‐1 expression and exposure on plasma membrane. In the same cells, Liraglutide exposure also reduced MAPK/NF‐kB activation, peroxynitrite levels, and EMV release.ConclusionsTNF‐α induced pro‐atherogenic alterations are amplified in endothelial cells chronically exposed to hyperglycemia in vivo. Liraglutide mitigates TNF‐α effects and reduces cell stress/damage indicators, such as endothelial microvesicle (EMV) release. These results foster the notion that Liraglutide could exert a protective effect against hyperglycemia and inflammation triggered endothelial dysfunction.
Islands, mainland, and terrestrial fragments: How isolation shapes plant diversity
Authors: Martín‐Queller Emi , Albert Cécile H. , Dumas Pierre‐Jean , Saatkamp Arne 
Published: July 2017

AbstractThe fragmentation of natural habitats is a major threat for biodiversity. However, the impact and spatial scale of natural isolation mechanisms leading to species loss, compared to anthropogenic fragmentation, are not clear, mainly due to differences between fragments and islands, such as matrix permeability. We studied a 500 km2 Mediterranean region in France, including urban habitat fragments, continuous habitat, and continental‐shelf islands. On the basis of 295 floristic relevés, we built species–area relationships to compare isolation in fragments after urbanization, with continuous habitat and continental‐shelf islands. We assumed either no dispersal, infinite dispersal, or estimated intermediate levels of habitat reachability through graph theory. Isolation mechanisms occurred in fragments but with a lower strength than in near‐shore islands, and most importantly affected perennial plants. Annual plants were less affected, probably due to their smaller size and shorter life cycle. Isolation occurred at landscape level in fragments and at patch level in islands. The amount of reachable habitat (accounting for spatial configuration) explained local species richness in both systems, but the amount of habitat (no consideration of spatial configuration) was already a good predictor. These results suggest an important role of habitat amount around fragments in mitigating the isolation effects observed in near‐shore islands, and the importance of carefully considering different functional groups.
Sorting things out: Assessing effects of unequal specimen biomass on DNA metabarcoding
Authors: Elbrecht Vasco , Peinert Bianca , Leese Florian 
Published: July 2017

AbstractEnvironmental bulk samples often contain many different taxa that vary several orders of magnitude in biomass. This can be problematic in DNA metabarcoding and metagenomic high‐throughput sequencing approaches, as large specimens contribute disproportionately high amounts of DNA template. Thus, a few specimens of high biomass will dominate the dataset, potentially leading to smaller specimens remaining undetected. Sorting of samples by specimen size (as a proxy for biomass) and balancing the amounts of tissue used per size fraction should improve detection rates, but this approach has not been systematically tested. Here, we explored the effects of size sorting on taxa detection using two freshwater macroinvertebrate bulk samples, collected from a low‐mountain stream in Germany. Specimens were morphologically identified and sorted into three size classes (body size < 2.5 × 5, 5 × 10, and up to 10 × 20 mm). Tissue powder from each size category was extracted individually and pooled based on tissue weight to simulate samples that were not sorted by biomass (“Unsorted”). Additionally, size fractions were pooled so that each specimen contributed approximately equal amounts of biomass (“Sorted”). Mock samples were amplified using four different DNA metabarcoding primer sets targeting the Cytochrome c oxidase I (COI) gene. Sorting taxa by size and pooling them proportionately according to their abundance lead to a more equal amplification of taxa compared to the processing of complete samples without sorting. The sorted samples recovered 30% more taxa than the unsorted samples at the same sequencing depth. Our results imply that sequencing depth can be decreased approximately fivefold when sorting the samples into three size classes and pooling by specimen abundance. Even coarse size sorting can substantially improve taxa detection using DNA metabarcoding. While high‐throughput sequencing will become more accessible and cheaper within the next years, sorting bulk samples by specimen biomass or size is a simple yet efficient method to reduce current sequencing costs.
