Tense from touch: Examining accidental interpersonal touch between consumers
Authors: Martin Brett A. S. , Nuttall Peter 
Published: September 2017

AbstractRetail shopping research recognizes that other consumers in a store can impact a consumer's experience. However, the effects of accidental interpersonal touch (AIT) are only beginning to emerge in the literature. The current research presents three field experiments to illuminate the process that drives AIT effects. This research is the first to show that AIT effects are driven by arousal; specifically tense arousal rather than energetic arousal. The findings build on prior research to investigate moderators of the AIT effect—trait anxiety and social visibility. The findings show that AIT effects are amplified for anxious female consumers and situations where store bystanders activate feelings of embarrassment. Theoretical and managerial implications are offered.
Sequence‐Independent DNA Nanogel as a Potential Drug Carrier
Authors: Zhang Weiqi , Tung Ching‐Hsuan 
Published: September 2017

AbstractDNA nanostructures largely rely on pairing DNA bases; thus, sequence designing is required. Here, this study demonstrates a sequence‐independent strategy to fabricate DNA nanogel (NG) inspired by cisplatin, a chemotherapeutic drug that acts as a DNA crosslinker. A simple heating and cooling of the genomic DNA extracts and cisplatin produces DNA NG with a size controlled by the heating time. Furthermore, the drug‐loaded NG is formulated by spontaneously mixing DNA segments, cisplatin, and doxorubicin. The in vitro cell studies demonstrate that the doxorubicin‐loaded NG alters the drug distribution in cells while its cytotoxic potential is well‐maintained. This chemotherapeutic‐inspired method provides a facile one‐pot and cost‐effective strategy to fabricate size‐controllable DNA NG that potentially acts as drug carrier.

Published: September 2017

AbstractOver the past two decades, biomass‐derived and biodegradable polylactide (PLA) has sparked tremendous attention as a sustainable alternative to traditional petroleum‐derived polymers for diverse applications. Unfortunately, the current applications of PLA have been mainly limited to biomedical and commodity fields, mostly because the poor heat resistance (resulting from low melting temperature) and hydrolysis stability make it hard to use as an engineering plastic. Stereocomplexation between enantiomeric poly(l‐lactide) (PLLA) and poly(d‐lactide) (PDLA) opens a new avenue toward PLA‐based engineering plastics with improved properties. The formation, crystal structure, properties, and potential applications of stereocomplex‐type PLA (SC‐PLA) are summarized by some research groups. However, since it is challenging to achieve full stereocomplexation from high‐molecular‐weight PLLA/PDLA blends and to avoid serious thermal degradation of the PLAs after complete melting, the advances and progress in the processing of SC‐PLA into useful products are quite rare in open publication. In this review, some important strategies for enhancing stereocomplex crystallization in practical processing operations are presented and recently developed processing technologies for SC‐PLA are highlighted, such as low‐temperature sintering. Furthermore, major challenges and future developments are briefly discussed. This review is expected to potentially open up new research activities in the processing of SC‐PLA.
A block matching based approach with multiple simultaneous templates for the real‐time 2D ultrasound tracking of liver vessels

Published: September 2017

PurposeThe implementation of motion management techniques in radiation therapy can aid in mitigating uncertainties and reducing margins. For motion management to be effective, it is necessary to track key structures both accurately and at a real‐time speed. Therefore, the focus of this work was to develop a 2D algorithm for the real‐time tracking of ultrasound features to aid in radiation therapy motion management.Materials and MethodsThe developed algorithm utilized a similarity measure‐based block matching algorithm incorporating training methods and multiple simultaneous templates. The algorithm is broken down into three primary components, all of which use normalized cross‐correlation (NCC) as a similarity metric. First, a global feature shift to account for gross displacements from the previous frame is determined using large block sizes which encompass the entirety of the feature. Second, the most similar reference frame is chosen from a series of training images that are accumulated during the first K frames of tracking to aid in contour consistency and provide a starting point for the localized template initialization. Finally, localized block matching is performed through the simultaneous use of both a training frame and the previous frame. The localized block matching utilizes a series of templates positioned at the boundary points of the training and previous contours. The weighted final boundary points from both the previous and the training frame are ultimately combined and used to determine an affine transformation from the previous frame to the current frame.ResultsA mean tracking error of 0.72 ± 1.25 mm was observed for 85 point‐landmarks across 39 ultrasound sequences relative to manual ground truth annotations. The image processing speed per landmark with the GPU implementation was between 41 and 165 frames per second (fps) during the training set accumulation, and between 73 and 234 fps after training set accumulation. Relative to a comparable multithreaded CPU approach using OpenMP, the GPU implementation resulted in speedups between −30% and 355% during training set accumulation, and between −37% and 639% postaccumulation.ConclusionsInitial implementations indicated an accuracy that was comparable to or exceeding those achieved by alternative 2D tracking methods, with a computational speed that is more than sufficient for real‐time applications in a radiation therapy environment. While the overall performance reached levels suitable for implementation in radiation therapy, the observed increase in failures for smaller features, as well as the algorithm's inability to be applied to nonconvex features warrants additional investigation to address the shortcomings observed.

Authors: Ho Grace W.K. , Bettencourt Amie , Gross Deborah A. 
Published: September 2017

ABSTRACTEntry into the child protection system in the US begins with a child maltreatment report. Some evidence suggests that report source and child age are related to report outcomes, but there has been no national study of these relationships. The purpose of this secondary data analysis was to describe the distribution of report sources for child physical abuse (CPA), and examine whether (a) the source of a report and (b) child age contribute to the likelihood of substantiation of the reported abuse. Multilevel logistic regressions were conducted using a US national sample of 204,414 children investigated for CPA in 2013 in a dataset obtained from the National Child Abuse and Neglect Data System. Results showed that fewer than one in seven children reported for CPA were confirmed victims of abuse. Professionally mandated reporters initiated the majority of CPA reports, and their reports were more likely to be substantiated compared with nonprofessionals. However, reports made by even the most accurate professional group (legal/law enforcement) had only a 26% chance of substantiation, and some professional groups had a lower likelihood of substantiation than nonprofessionals. Reports made by professionals were less likely to be substantiated as child age increased. More research is warranted to develop and test the effectiveness of training programs to improve CPA reporting and identification.
Addition of oral iron to plasma transfusion in human congenital hypotransferrinemia: A 10‐year observational follow‐up with the effects on hematological parameters and growth
Authors: Aslan Deniz 
Published: September 2017

AbstractCongenital hypotransferrinemia (OMIM 209300) is an extremely rare disorder of inherited iron metabolism. Since its description in 1961, only 16 cases have been reported. The defective gene and molecular defect causing this disorder and clinicolaboratory findings seen in the homozygous and heterozygous states have been documented in both humans and mice. However, due to the lack of follow‐up studies of the described cases, the long‐term prognosis remains unknown. We present a 10‐year observational follow‐up of a patient previously diagnosed on a molecular basis who was treated with a unique therapy of plasma transfusion fortified
with oral iron, with satisfactory clinicolaboratory responses.

Published: September 2017

AbstractBackgroundIn low‐ and middle‐income countries (LMICs), inconsistent or delayed management of fever contributes to poor outcomes among pediatric patients with cancer. We hypothesized that standardizing practice with a clinical algorithm adapted to local resources would improve outcomes. Therefore, we developed a resource‐specific algorithm for fever management in Davao City, Philippines. The primary objective of this study was to evaluate adherence to the algorithm.ProcedureThis was a prospective cohort study of algorithm adherence to assess the types of deviation, reasons for deviation, and pathogens isolated. All pediatric oncology patients who were admitted with fever (defined as an axillary temperature  >37.7°C on one occasion or ≥37.4°C on two occasions 1 hr apart) or who developed fever within 48 hr of admission were included. Univariate and multiple linear regression analyses were used to determine the relation between clinical predictors and length of hospitalization.ResultsDuring the study, 93 patients had 141 qualifying febrile episodes. Even though the algorithm was designed locally, deviations occurred in 70 (50%) of 141 febrile episodes on day 0, reflecting implementation barriers at the patient, provider, and institutional levels. There were 259 deviations during the first 7 days of admission in 92 (65%) of 141 patient episodes. Failure to identify high‐risk patients, missed antimicrobial doses, and pathogen isolation were associated with prolonged hospitalization.ConclusionsMonitoring algorithm adherence helps in assessing the quality of pediatric oncology care in LMICs and identifying opportunities for improvement. Measures that decrease high‐frequency/high‐impact algorithm deviations may shorten hospitalizations and improve healthcare use in LMICs.
Pathology and genomics of pediatric melanoma: A critical reexamination and new insights
Authors: Bahrami Armita , Barnhill Raymond L. 
Published: September 2017

AbstractThe clinicopathologic features of pediatric melanoma are distinct from those of the adult counterpart. For example, most childhood melanomas exhibit a uniquely favorable biologic behavior, save for those arising in large/giant congenital nevi. Recent studies suggest that the characteristically favorable biologic behavior of childhood melanoma may be related to extreme telomere shortening and dysfunction in the cancer cells. Herein, we review the genomic profiles that have been defined for the different subtypes of pediatric melanoma and particularly emphasize the potential prognostic value of telomerase reverse transcriptase alterations for these tumors.

Published: September 2017

AbstractIntroductionRosemary (Rosmarinus officinalis L.) is an aromatic plant common in Tunisia and it is widely consumed as a tea in traditional cuisine and in folk medicine to treat various illnesses. Currently, most research efforts have been focused on rosemary essential oil, alcoholic and aqueous extracts, however, little is reported on rosemary infusion composition.ObjectiveTo investigate compounds present in rosemary tea obtained from Rosmarinus officinalis L. collected in a sub‐humid area of Tunisia in order to assess whether the traditional rosemary tea preparation method could be considered as a reference method for rosemary's compounds extraction.MethodologyQualitative characterisation of Rosmarinus officinalis tea obtained after rosemary infusion in boiled water was determined by high performance liquid chromatography coupled with electrospray ionisation quadrupole time‐of‐flight mass spectrometry (HPLC‐ESI‐QTOF‐MS). Quantitative analysis relies on high performance liquid chromatography with diode array detector (HPLC‐DAD).ResultsForty‐nine compounds belonging to six families, namely flavonoids, phenolic acids, phenolic terpenes, jasmonate, phenolic glycosides, and lignans were identified. To the best of the authors' knowledge eucommin A is characterised for the first time in rosemary. Rosmarinic acid (158.13 μg/g dried rosemary) was the main compound followed then by feruloylnepitrin (100.87 μg/g) and luteolin‐3′‐O‐(2″‐O‐acetyl)‐β‐d‐glucuronide (44.04 μg/g). Among quantified compounds, luteolin‐7‐O‐rutinoside was the compound with the lowest concentration.ConclusionThe infusion method allows several polyphenols present in rosemary tea to be extracted, therefore it could be a reference method for rosemary's compounds extraction. Moreover, traditional Tunisian Rosmarinus officinalis tea consumption is of interest for its rich phenolic content. Copyright © 2017 John Wiley & Sons, Ltd.
The use of 1H–NMR Metabolomics to Optimise the Extraction and Preliminary Identification of Anthelmintic Products from the Leaves of Lysiloma latisiliquum
Authors: Hernández‐Bolio Gloria Ivonne , Kutzner Erika , Eisenreich Wolfgang , de Jesús Torres‐Acosta Juan Felipe , Peña‐Rodríguez Luis Manuel 
Published: September 2017

AbstractIntroductionTannin‐rich forages are recognised as an important alternative for the control of gastrointestinal nematodes in small ruminants. Lysiloma latisiliquum, a forage commonly consumed by goats and sheep, has shown anthelmintic activity when tested against Haemonchus contortus. However, to date, the metabolites responsible for the activity are not known.ObjectiveTo use 1H–NMR metabolomics in the extraction and identification of anthelmintic metabolites from L. latisiliquum.MethodologyEight different solvent systems were compared for the optimum extraction of anthelmintic metabolites from L. latisiliquum. 1H–NMR spectra of the tannin‐free extracts were measured in methanol‐d4 using trimethylsilylpropanoic acid (TSP) as internal standard. Extracts were also evaluated for their anthelmintic activity using the larval exsheathment inhibition assay against H. contortus. These data were correlated by multivariate analysis [principal component analysis (PCA) and orthogonal projections to latent structures discriminant analysis (OPLS‐DA)] and analysed. To validate the results obtained after the OPLS‐DA, a bioassay‐guided isolation of bioactive metabolites was conducted.ResultsThe PCA of the 1H–NMR data allowed the identification of hydrophilic solvents as those best suited for the extraction of anthelmintics from L. latisiliquum and indicated that the bioactive metabolites are high‐polarity, glycosylated products. Similarly, OPLS‐DA of the data enabled the detection of activity‐related signals, assigned to the glycosylated metabolites quercitrin and arbutin obtained from the bioassay‐guided purification of the extract.ConclusionThe results of this investigation confirm metabolomics as a useful tool in the detection of bioactive metabolites in plants without previous phytochemical studies.

Influence of Particle Size on the Combustion of CL‐20/HTPB Propellants
Authors: Kalman Joseph , Essel Jonathan 
Published: September 2017

AbstractThe effect of nitramine particle size on the combustion behavior of inert binder based propellants has been extensively studied for RDX and HMX, but not CL‐20. Although materials such as RDX and HMX are useful for particular combustion applications, CL‐20 has a greater potential to improve the oxygen balance and energy density of a propellant. The current work investigates the effect of CL‐20 particle size on the combustion of CL‐20/HTPB propellants down to submicrometer sizes. An influence of particle size on the burning rate and combustion mechanism is reported. The 30 micrometer formulation burning rate data showed evidence of convective burning specifically at higher pressures, but the pressure dependence was comparable to neat CL‐20 at pressures below 8 MPa. A change in the combustion mechanism of the submicrometer formulation as a function of pressure was determined to be a result of the interaction of the propellant flame and the combustion residue. Data suggested that at low pressures diffusion in terms of active cooling was dominant for the submicrometer formulation. Higher pressure data for both the submicrometer and 3 micrometer formulations suggest the degree of active cooling is decreased as the burning rate pressure exponent is near 0.5 for both propellants. The indirect evidence for the presence of a melt layer for CL‐20 propellants is discussed.
Formations on directed cycles with bearing‐only measurements
Authors: Trinh Minh Hoang , Mukherjee Dwaipayan , Zelazo Daniel , Ahn Hyo‐Sung 
Published: September 2017

SummaryThis paper studies a bearing‐only–based formation control problem for a group of single‐integrator agents with directed cycle sensing topology. In a 2‐dimensional space, a necessary and sufficient condition for the set of desired bearing vectors to be feasible is derived. Then, we propose a bearing‐only control law for every agent and prove that the formation asymptotically converges to a formation specified by a set of feasible desired bearing vectors. Analysis of the equilibrium formations in the plane for a 3‐agent system and subsequent extension to an n‐agent system is provided. We further extend the analysis on directed triangular formation into a 3‐dimensional space. Finally, simulations validate the theoretical results.
Adaptive quantized tracking control for uncertain switched nonstrict‐feedback nonlinear systems with discrete and distributed time‐varying delays
Authors: Yu Zhaoxu , Dong Yan , Li Shugang , Li Fangfei 
Published: September 2017

SummaryThis paper is concerned with an adaptive tracking problem for a more general class of switched nonstrict‐feedback nonlinear time‐delay systems in the presence of quantized input. The system structure in a nonstrict‐feedback form, the discrete and distributed time‐varying delays, the sector‐bounded quantized input, and arbitrary switching behavior are involved in the considered systems. In particular, to overcome the difficulties from the distributed time‐varying delays and the sector‐bounded quantized input, the mean‐value theorem for integrals and some special techniques are exploited respectively. Moreover, by combining the Lyapunov‐Razumikhin method, dynamic surface control technique, fuzzy logic systems approximation, and variable separation technique, a quadratic common Lyapunov function is easily built for all subsystems and a common adaptive quantized control scheme containing only 1 adaptive parameter is proposed. It is shown that the tracking error converges to an adjustable neighborhood of the origin whereas all signals of the closed‐loop systems are semiglobally uniformly ultimately bounded. Finally, 2 simulation examples are provided to verify the feasibility and effectiveness of the proposed design methodology.
An Optical pH Sensor Based on Diazocine
Authors: Liu Yanan , Song Zuwei , Gao Libin , Li Jianzhong 
Published: September 2017

AbstractA novel excellent candidate for the optical pH sensor based on diazocine is presented in this paper. Diazocine serves as a cyclooctatetraene analogy which has a nonplanar 8‐membered ring structure with nitrogen atoms. It is the first example to present the optical properties of cyclooctatetraene analogy with chemical (trifluoroacetic acid) pH gradient by UV‐visible absorption and NMR spectra. Specifically, reversibility of protonation/deprotonation reaction is clearly demonstrated by the UV spectra when triethylamine is added. In this work, we also investigate the spectral properties and sensitivity of polydiaryldibenzo[1, 5]diazocines (PBDA) retaining its optical properties in liquid state. This study features an innovative detection system for H+ measurement through a low cost optical device by means of polymer spin‐coating on the support material (PE films). Furthermore, the optical characteristic collected in the solid state is in excellent agreement with the data previously found in the liquid state. The transient response of optical device is very rapid upon pH change from 6.9 to 1.5. As a result, optical device based on PBDA can be applied to test H+ or pH in organic or aqueous solvent and even extended to sensing of some other analytes.
Magnetic Alloy‐MWNT Heterostructure as Efficient Electromagnetic Wave Suppressors in Soft Nanocomposites
Authors: Menon Aishwarya V. , Madras Giridhar , Bose Suryasarathi 
Published: September 2017

AbstractFeNi (iron‐nickel) alloy particles were coated with MWNTs (Multiwalled carbon nanotubes) using simple ball milling technique at various alloy to MWNT ratios. These hybrid heterostructure were then dispersed in PVDF/TPU (Polyvinylidene fluoride/ Thermoplastic polyurethane) blends to develop flexible composite materials that can shield electromagnetic (EM) radiations. These alloy particles coated with MWNT localise mostly in the TPU phase of the binary blends. The shielding effectiveness (SE) measurements obtained from the scattering parameters reveal that for a particular ratio of FeNi/MWNT (3:1), the SE was the highest (‐35.7 dB) among the different composites studied here and manifested in improved microwave absorption in the blends. The absorption driven shielding is due to various polarization in the shield, thereby increasing the dielectric loss. It was observed that these MWNT wrapped magnetic alloy particles shielded the incoming EM radiations more effectively as compared to only MWNTs or only alloy particles. The soft nanocomposites designed here absorb up to 95 % of the incoming EM radiations. The lowest skin depth and highest specific EMI (Electromagnetic interference) shielding attained was 1.4 mm and −20.5 dB cm2 g−1 respectively for composites containing FeNi/MWNT‐ 3:1. The attenuation constant derived from different parameters of these blends were also analysed in order to develop a multi‐layered structure, having absorption‐multiple reflection‐absorption pathways. This was used to assess the effect of different layers and their sequence in the multi‐layered structure on final EM wave attenuation. Interestingly, multi‐layered architecture with a similar thickness showed three‐fold increase in the total shielding as compared to their bulk counterpart.
