AbstractFlexible and wearable strain sensor has drawn a great deal of attention owing to its wide applications in health monitoring, human–machine interfaces, soft robotics, etc. Microstructural design on the conductive layer of strain sensor effectively improves its performance in linearity and hysteresis effect, yet the process of achieving microstructure is complicated. Leather, a kind of conventional flexible materials to manufacture clothes, shoes, etc., possesses natural hierarchical structure that consists of collagen fiber. Herein, leather is used as a substrate to fabricate a strain sensor by filtration of conductive nanomaterials aqueous dispersion. It is found that 0D conductive nanomaterials can be adsorbed in leather to form conductive pathway with leather‐like microstructure. The as‐prepared sensor with such microstructure not only inherits the air permeability, mechanical property, and biocompatibility from leather, but also displays linearity performance within three regions, low hysteresis effect, short response time, high stability, stretchability, as well as good durability. Kirigami is introduced to endow the leather‐based sensor with stretchability. Such a sensor is applicable to human motion monitoring and shape perception of robotic arm.

Published: September 2019

BackgroundOptimizing intranasal distribution and retention of nasal sprays is essential in the management of patients with chronic rhinosinusitis (CRS), including those that have had functional endoscopic sinus surgery (FESS). Despite multiple existing distribution studies, there remains a need for a technique that allows regionalization of particle deposition within a patient's unique 3‐dimensional (3D) geometry without exposing the patient to radiation.MethodsSeven participants delivered normal saline containing a gadolinium‐based contrast agent (GBCA) by either saline irrigation or nasal sprays on 1 side of the nasal cavity. The saline irrigation group included 2 participants (both healthy) while the nasal spray group included 5 participants (2 healthy, 2 post‐FESS patients, 1 CRS patient without any sinus surgery). The distribution of new signal enhancement was assessed on each participant using magnetic resonance imaging (MRI). Serial scans were performed over an interval of 4 minutes in the nasal spray group to assess changes in intranasal distribution over time.ResultsSignal enhancement was widespread within the nasal cavities and maxillary sinuses of participants (both healthy) that underwent sinus irrigation. For the nasal spray participants, the hotspots for signal enhancement were similar regardless of disease status or previous history of surgery. These included the internal nasal valve, anterior septum, inferior surface of the inferior turbinate, nasal floor, and nasopharynx. No signal enhancement was detected with nasal sprays in either unoperated or operated paranasal sinuses.ConclusionA technique has been developed using MRI evaluation of radioopaque contrast to characterize the temporospatial distribution of topical drug delivery within the sinonasal cavities.

Published: September 2019

AbstractThe coupled mechanical resonators (MRs) are the prominent candidate for studying macroscopic quantum coherence. The prerequisite for observing macroscopic mechanical coherence is cooling the MRs to their ground state. Here, a theoretical scheme is proposed for improving the cooling of two coupled MRs by imposing frequency modulation (FM) upon the system to suppress the Stokes heating processes. By the methods of covariance analysis and numerical simulations, it is demonstrated that the cooling of double MRs can be realized in both stable and unstable regions with high efficiency compared to the cooling without FM, even if in unresolved sideband (USB) regime. By modulating the parameters appropriately, the cooling efficiencies of two MRs can be flexibly adjusted.
Disturbance compensation based model‐free adaptive tracking control for nonlinear systems with unknown disturbance
Authors: Li Haifeng , Wang Yingchun , Pang Mengmeng 
Published: September 2019

AbstractThis paper considers a novel model‐free adaptive tracking control for nonlinear perturbed systems. A general dynamic linearization model with disturbance input is first developed for nonlinear systems based on the pseudo‐partial derivatives (PPDs) method and input/output (I/O) data. Due to the unknown disturbance input, an online disturbance estimation algorithm is proposed based on optimization by minimizing a cost function. Furthermore, an adaptive tracking control strategy with disturbance compensation is developed, such that the tracking error of nonlinear systems is convergent and closed‐loop systems are strongly robust. Finally, a comparing simulation is provided to demonstrate the effectiveness of the proposed approach.

Published: September 2019

AbstractIntroductionStudies have shown that high levels of the fibrinogen (FIB) are related to cognitive deficits. However, the relationship between fibrinogen and cognitive deficit after stroke remains unclear. Therefore, we explored the relationship between plasma fibrinogen and post‐stroke cognitive impairment (PSCI).MethodsThis study is carried out in the First Affiliated Hospital of Wenzhou Medical University, Wenzhou, Zhejiang Province, China. A total of 210 patients with acute ischemic stroke were enrolled in this study. Ultimately, 134 patients completed 3‐month follow‐up. Blood samples were collected at hospital admission. Cognitive function was evaluated 3 months after stroke. All patients underwent the Mini‐Mental State Examination (MMSE) after 3 months.ResultsHigher levels of fibrinogen were observed in patients with post‐stroke cognitive impairment compared with the non‐PSCI group (p < .001). Additionally, elevated plasma fibrinogen levels were independently associated with PSCI (odds ratio [OR] = 2.000, 95% CI 1.062–3.770 p = .032). The plasma fibrinogen levels were negatively correlated with the 3‐month MMSE scores (r = −.171, p = .048). In a multivariate linear regression, FIB was negatively associated with the 3‐month MMSE scores after adjustment for the other variables (β = −0.782, p = .035).ConclusionHigh levels of plasma fibrinogen were associated with the presence and severity of PSCI.
Managerial perspectives on drivers for and barriers to sustainable supply chain management implementation: Evidence from New Zealand

Published: September 2019

AbstractThe purpose of this paper is to examine the factors that drive or prevent companies' implementation of sustainable supply chain management (SSCM) practices. To this end, we interviewed 29 senior managers from 23 New Zealand‐based companies. The key reported drivers were customer expectation, top management commitment, moral and ethical values of managers, reputation management, and economic and operational benefits. Conversely, cost concerns, strategic and structural restraints, supplier and customer issues, and a lack of effective regulations were cited as critical obstacles to SSCM implementation. Thus, the evidence from our findings provides support for both instrumental and normative logics for SSCM implementation. The findings further indicate that, in general, instrumental and normative logics are congruent; however, varied tensions arise when managers seek to simultaneously address competing yet desirable SSCM aspects. Accordingly, we argue that it is imperative to understand, work through, and manage such tensions as balancing divergent sustainability aspects holds considerable potential for successful SSCM implementation.

AbstractBackgroundMarital status has long been widely recognized as a determinant of cancer survival. However, only few analytical studies have been conducted on this issue considering heterogeneous factors. The aim of this study was to assess the effects of marital status on postoperative survival of patients with less differentiated (poor/anaplastic) hepatocellular carcinoma (HCC).MethodsWe retrospectively analyzed 1581 postoperative patients diagnosed with poor/anaplastic HCC from the Surveillance, Epidemiology, and End Results database between 2004 and 2015. Patients were classified into married, never married, divorced/separated and widowed groups. Kaplan‐Meier analysis and multivariate Cox regression analysis were used to analyze the effects of marital status on HCC cause‐specific survival (HCSS).ResultsCompared with married patients, there were no significant differences in HCSS for unmarried, never married, divorced/separated and widowed patients both in univariate (5‐year HCSS: 36.0% vs 36.3%, 36.0% vs 32.4%, 36.0% vs 40.2%, 36.0% vs 36.3%, respectively, all P > .05) and multivariate analysis (all P > .05). Furthermore, in stratified analyses according to sex, age, and tumor size, compared with married patients, there were also no significant differences for never married, divorced/separated, and widowed patients both in univariate (all P > .05) and multivariate analysis (all P > .05).ConclusionsFor patients with poor/anaplastic differentiated HCC treated with surgical resection, marital status has no prognostic role in survival.

AbstractCracks adversely affect the prognosis and survival of the teeth. Thus, the possibility of presence of crack should be considered after endodontic treatment and before the initiation of periodontal/prosthetic treatments. Attempts must be made to restore cracked teeth with efficient restorative materials to increase their survival and prevent additional costs.
Donut Assembly of Nanoparticles with High Catalytic Efficiency for Hydrogen Gas Generation from Ammonia Borane

Published: September 2019

AbstractPolymer‐supported transition metal nano particles usually exhibited low catalytic efficiency due to the long diffusion length for the reactants to reach the catalytic center. Herein, we used cyclic polymers to construct donut‐like assembly with two cyclic macromolecules sandwiching a layer of metal NPs. Doping Rh into the nano particles led to extremely active catalysts for ammonia borane decomposition with a high TOF of 780 min−1. We attributed the high efficiency to the reduced diffusion length in this special assembly. Light‐promoted effect was also demonstrated with TOF further elevated to 980 min−1. The modular nature of this design also permitted subsequent structural modification to achieve high stability with TON reaching over 2×106.
Chirality as an Important Factor for the Development of New Antiepileptic Drugs
Authors: Abram Michał , Jakubiec Marcin , Kamiński Krzysztof 
Published: September 2019

AbstractIn recent years, chiral molecules (especially enantiomers) have occupied a significant place in pharmaceutical industry and have played a prominent role in the development of new drugs. Individual stereoisomers exhibit marked differences in pharmacodynamic, pharmacokinetic, and toxicological properties. Therefore, there is currently considerable interest in fully characterizing and examining both enantiomers in the early stages of new drug development. Despite the fact that epilepsy is a complex disease and that a given drug's mechanism of action may be multidirectional and not always fully understood, significant differences have been observed in the anticonvulsant activity of individual stereoisomers. Therefore, between 1996 and 2018, among 14 new antiepileptic drugs (AEDs) approved for the treatment of epilepsy, as many as seven are chiral and introduced to the market in the single‐enantiomer (or diastereomer) form. This review provides an overview of the impact of chirality on the development and discovery of new AEDs that have entered into clinical trials or preclinical studies. These new AEDs were developed by applying the single‐enantiomer approval strategy. Herein we focus our attention on the main synthetic pathways of stereoisomers, as well as on the influence of chirality on pharmacodynamic, pharmacokinetic, and/or toxicological properties.
“Act thin, stay thin”: Commercialization, behavior modification, and group weight control
Authors: Parr Jessica 
Published: September 2019

AbstractIn 1968, Weight Watchers International introduced behavior modification practices to their established commercial program. At the time, the addition of behavioral psychology gave Weight Watchers a distinct advantage over the many competing weight control groups in postwar America. The process of combining group therapy with a controlled diet plan, behavior techniques and later, exercise, has significantly influenced American popular culture. This article considers how the commercialization of group weight control impacted the development and dissemination of a new multidimensional approach for weight management and how this has shaped popular ideas associated with dieting and wider understandings of healthy living.
Export Diversification and CO2 Emissions: An Augmented Environmental Kuznets Curve
Authors: Mania Elodie 
Published: September 2019

AbstractThe mitigation of global warming by reducing greenhouse gas emissions has been the objective of successive negotiations and agreements between nations. At the same time, there is a consensus on the virtues of export diversification for the development of less advanced countries. This article investigates the effect of export diversification on CO2 emissions in the context of an environmental Kuznets curve hypothesis in 98 developed and developing countries during the period 1995–2013. Using short‐run (system Generalized Method of Moments) and long‐run (Pooled Mean Group) estimation methods, we find that the environmental Kuznets curve is valid and that export diversification has a positive effect on CO2 emissions. © 2019 John Wiley & Sons, Ltd.
Assessing the potential of additive manufacturing for the provision of spare parts
Authors: Heinen J. Jakob , Hoberg Kai 
Published: September 2019

AbstractSpare parts are a particularly interesting application for switching production from traditional manufacturing (TM) to additive manufacturing (AM). Research assessing AM has primarily addressed cost models centering on the production process or the operations management of separate spare parts. By combining case study, modeling, and design science elements, we adopt a holistic perspective and develop a design to examine the systematic leverage of AM in spare parts operations. Contextually grounded in problems faced by a leading material handling equipment manufacturer that is challenged by common characteristics of after‐sales operations, we engage with practice to propose a portfolio level analysis examining the switchover share from TM to AM. Using a data set of 53,457 spare parts over 9 years, we find that up to 8% of stock keeping units (SKUs) and 2% of total units supplied could be produced using AM, even if unit production costs are four times those of TM. This result is driven by low demand, high fixed costs, and minimum order quantities in TM. Finally, we present the evaluation by the case company's management and highlight five areas of opportunity and challenge.

Published: September 2019

AbstractWe conducted comprehensive Raman and Fourier transform infrared (FTIR) spectroscopic studies on the whole rock and lithic clasts of Northwest Africa (NWA) 4884 to constrain its igneous mineralogy and metamorphic characteristics. NWA 4884 is composed of mostly clinopyroxene (25.8 vol.%), pigeonite (16.6 vol.%), plagioclase (26.6 vol.%), maskelynite (8.1 vol.%), olivine (20.7 vol.%), minor tridymite (1.0 vol.%), quartz (0.2 vol.%), and ilmenite (0.5 vol.%). Lithic clasts contain mafic rocks including plutonic ultramafic cumulate, olivine gabbro, mare basalt, and feldspathic rocks including noritic anorthosite and impact melt breccia. Raman and FTIR spectroscopic analyses are combined to investigate the shock history of this breccia and revealed that NWA 4884 is highly shocked (17.9–48.1 GPa recorded in plagioclase). The combination of bulk composition and remote sensing data provides possible source regions of NWA 4884: the southern Lacus Veris (20.5°S, 84.5°W) within Orientale basin and the western mare unit (45.3°N, 151.3°E) of Campbell Crater. The pairing relationship among NWA 4884, Yamato 793274, Queen Alexandra Range 94281, and NWA 7611 is supported by their petrographic, mineral, and compositional similarities. Our work demonstrates the potential of Raman and FTIR spectroscopies to shed light on igneous petrology and the bombardment history of the Moon.
Response and driving factors of soil microbial diversity related to global nitrogen addition
Authors: Yang Yang , Cheng Huan , Gao Han , An Shaoshan 
Published: September 2019

AbstractIt is increasingly evident that soil microorganisms play a substantial role in ecosystem processes, which occupy a large part of genetic diversity in terrestrial ecosystems. During the past decades, nitrogen (N) addition induced by human has been regarded as the main driver of global changes to soil microecological processes. Although growing studies demonstrated the loss of biodiversity due to N addition in regional scale, the role of global N addition on soil microbial diversity is lacking. Here, we sought to illuminate the impacts and driving factors of soil microbial diversity in relation to global N addition using a meta‐analysis from 1,078 paired observations in 212 studies. We found a negative influence of global N addition on soil microbial diversity, and the reduction of soil microbial diversity was determined by land use types, N fertility types, methods, N addition rates, and duration. In fact, there was a linear decrease of soil microbial diversity along the latitudinal gradient, and N addition‐induced acidification was the predominant contributor to the reduction of soil microbial diversity. Both of soil properties (pH, soil organic carbon, soil total N, and soil microbial biomass C) and climatic factors (mean annual temperature and mean annual precipitation) determined soil microbial diversity under global N addition. It was noted that soil fungal diversity was more adaptable to acidic environments, whereas soil bacterial diversity was more adaptable to neutral environment. Most importantly, soil fungal diversity was more sensitive than soil bacterial diversity under global N addition. Our meta‐analysis provides a new insight in understanding the key role of global N addition in shaping soil microbial diversity. Thereby, we recommend that future research should be focused on the soil microbial processes using manipulative controlled experiments, which identify the available measures to reduce the loss of soil microbial diversity globally.

Mapping Relative Differences in Human Salivary Gland Secretions by Dried Saliva Spot Sampling and nanoLC–MS/MS
Authors: Schulte Fabian , Hasturk Hatice , Hardt Markus 
Published: September 2019

AbstractDried saliva spot sampling is a minimally invasive technique for the spatial mapping of salivary protein distribution in the oral cavity. In conjunction with untargeted nano‐flow liquid chromatography tandem mass spectrometry (nanoLC–MS/MS) analysis, DSS is used to compare the proteomes secreted by unstimulated parotid and submandibular/sublingual salivary glands. Two hundred and twenty proteins show a statistically significant association with parotid gland secretion, while 30 proteins are at least tenfold more abundant in the submandibular/sublingual glands. Protein identifications and label‐free quantifications are highly reproducible across the paired glands on three consecutive days, enabling to establish the core proteome of glandular secretions categorized into eight salivary protein groups according to their biological functions. The data suggest that the relative contributions of the salivary glands fine‐tune the biological activity of human saliva via medium‐abundant proteins. A number of biomarker candidates for Sjögren's syndrome are observed among the gland‐specifically expressed proteins, which indicates that glandular origin is an important factor to consider in salivary biomarker discovery.
Theoretical Study on Energetic Derivatives Based on 3,7‐Bis(Alkenyl)‐2,4,6,8‐Tetraazabicyclo[3.3.0]Octane

Published: September 2019

AbstractDensity functional theory at B3LYP/6‐311G (d,p) level was employed to investigate the physicochemical properties of the 3,7‐bis(alkenyl)‐2,4,6,8‐tetraazabicyclo[3.3.0]octane based energetic materials. Their frontier molecular orbital energy gaps, heats of formation, detonation properties and thermal stabilities were calculated. The results show that the frontier molecular orbital energy gaps were from 3.56 eV (A2) to 5.43 eV (C3); the heats of formation were from −154.8 (A5) to 3007.2 kJ mol−1 (C2); the detonation velocities were from 5.22 (A1) to 8.90 km s−1 (A5) while the detonation pressures were from 10.8 (A1) to 36.4 GPa (A5). In view of the bond dissociation energies, the data were found to be from 8.9 (A4) to 321.8 kJ mol−1 (A1). Take both of detonation properties and bond dissociation energies into consideration, compounds A5 and C5 were finally selected as candidates for high energy density materials since they have excellent detonation properties and acceptable thermal stabilities.
