An Analysis ofSDNControllers Software
Authors: Hu Tao , Yi Peng , Hu Yuxiang 
Published: December 2019

AbstractMulti‐controllers can effectively improve the scalability and stability of the control plane in software‐defined networking (SDN) and is becoming a promising solution in large‐scale networks. In this article, we present a research survey for multi‐controller SDN control plane. We categorize the multi‐controller research into two aspects: homogeneous control plane and heterogeneous control plane. For homogeneous control plane, the network uses multiple same types of controllers to achieve the integrative control of the network. The homogeneous structure provides convenience for unified management and maintenance, but poses four critical problems: extending the number of controllers; processing load variance resulting in load imbalance on controllers; unreasonable placement causing low availability; conflicting strategy going against consistency. Heterogeneous multi‐controller SDN control plane that employs different types of controllers has been recently proposed to improve the utilization of control resource and the operation security of control plane. However, due to the increasing number of backdoors and various programming languages, the heterogeneous structure suffers from diverse vulnerabilities and incompatibility problems of different types of controllers. Thus, security and convergence of heterogeneous controllers become two important research topics. We present the research challenges and existing solutions of the aforementioned problems and further propose some promising future researches.

Published: December 2019

AbstractWhile broadly known that 5G is the next big leap in wireless communication, it must not be forgotten that the telecommunication sector is supported and greatly depends on the safety and performance of physical infrastructures. Masts and towers used for broadcasting of radio and television have been gradually assimilated by the public, and now the attention is on the large number of smaller masts, towers, and poles used for mobile networks. However, most of the general public is unaware of the engineering and expert knowledge behind these common structures; masts, towers, and poles represent the most important structures for the installation of the radio equipment used in transmission of the electromagnetic waves, that provide services of unquestionable importance. Over the last few decades, the demand for these types of structures has increased due to the requirements for their use in the telecommunication sector, and the advent of mobile communication made this demand even greater. This article introduces and discusses the fundamental elements needed for safety assessment of communication structures, presenting the insufficiencies of current design methodologies, and concluding with a comprehensive research proposal aiming to improve the safety of the telecommunication sector.
Mobility Management in D2D
Authors: Shih Mei‐Ju 
Published: December 2019

AbstractD2D mobility management is important when D2D communication is integrated to the 5G cellular network. This article provides the D2D mobility management techniques from both industrial standards (i.e. 3GPP) and academic research perspectives. In 3GPP Rel‐12, D2D mobility management aims to ensure the D2D UE can (re)select a cell or hand over to a target BS, which supports the D2D communication. In 3GPP Rel‐13, D2D communication is extended for UE‐to‐Network Relay operation, so the mobility management focuses on how to select a qualified Relay UE or Remote UE. In 3GPP Rel‐14 and Rel‐15, D2D communication is used for the vehicular network, so the mobility management copes with the handover to a target BS supporting V2X communication and the inter‐PLMN sidelink reception. Both idle mode mobility and connected mode mobility should be taken into account when the D2D communication is deployed in the cellular network. Nevertheless, the state‐of‐the‐art research progress has shown that the D2D mobility management can further consider various handover schemes (e.g. Joint Handover, Half Handover, Sidelink‐Assisted Handover), handover decision approach (e.g. considering the sidelink signal quality), and UE‐to‐Network Relay operation to achieve D2D service continuity. The overview of D2D mobility management in 3GPP and academic research may serve as a foundation when we further envision the D2D mobility management in 5G, especially the 5G NR V2X.

Published: December 2019

AbstractDevice‐to‐device (D2D) communication has emerged as a promising technology for the next‐generation mobile communication networks and wireless systems (5G). As an underlay network of conventional cellular networks, e.g. LTE and 5G network, D2D communications have shown great potential in improving communication capability, erasing communication delay, reducing power dissipation, and fostering multifarious new applications and services. In spite of the significant benefits, new application scenarios and system architecture expose D2D services into specific security and privacy threats and issues. These issues hinder the success of various D2D services. In this article, we explore a security architecture for D2D communications under 5G framework. Under this architecture, we investigate potential security and privacy threats and specify security and privacy requirements for designing a security and privacy, preserving D2D system. The state‐of‐the‐art solutions on security and privacy in D2D communications are reviewed comprehensively and intensively and evaluated under the security architecture. The analysis results show the features and drawbacks of existing works when coping with these security and privacy threats and requirements. Finally, we point out open research issues from the existing works and inspire future research efforts.

Published: December 2019

AbstractWe show that the onset pressure for appreciable conductivity in layered copper‐halide perovskites can decrease by ca. 50 GPa upon replacement of Cl with Br. Layered Cu–Cl perovskites require pressures >50 GPa to show a conductivity of 10−4 S cm−1, whereas here a Cu–Br congener, (EA)2CuBr4 (EA=ethylammonium), exhibits conductivity as high as 2×10−3 S cm−1 at only 2.6 GPa, and 0.17 S cm−1 at 59 GPa. Substitution of higher‐energy Br 4p for Cl 3p orbitals lowers the charge‐transfer band gap of the perovskite by 0.9 eV. This 1.7 eV band gap decreases to 0.3 eV at 65 GPa. High‐pressure X‐ray diffraction, optical absorption, and transport measurements, and density functional theory calculations allow us to track compression‐induced structural and electronic changes. The notable enhancement of the Br perovskite's electronic response to pressure may be attributed to more diffuse Br valence orbitals relative to Cl orbitals. This work brings the compression‐induced conductivity of Cu‐halide perovskites to more technologically accessible pressures.

Back to Basics: Medication Safety
Authors: Spruce Lisa 
Published: December 2019

ABSTRACTPerioperative nurses administer some medications but are primarily responsible for obtaining, preparing, and documenting medications. Unlike personnel in many other patient care areas, perioperative personnel may not have immediate access to a pharmacist; this lack of pharmacy support can complicate medication administration processes. A variety of medication errors occur in the perioperative setting and can negatively affect patients and personnel. Perioperative nurses should review regulatory information and professional organization guidance documents when they work with other health care team members to address medication safety issues. Some recommendations include submitting clear medication orders, using aseptic technique when transferring medications to the sterile field, and using standardized labeling. In addition, perioperative nurses should obtain only one patient's medications from a dispensing unit at a time and prepare one medication at a time. After reviewing this article and the supporting literature, perioperative nurses should have increased knowledge about medication safety.

Toughness improvement of novel biobased aromatic polyamide/SEBS/organoclay ternary hybrids
Authors: Lafranche Eric , Krawczak Patricia 
Published: December 2019

ABSTRACTBiobased aromatic polyamide/organoclay (Cloisite30B, C30B) nanocomposites were melt‐compounded with reactive and nonreactive styrene–ethylene–butylene–styrene (SEBS) rubbers at different weight contents to form ternary and quaternary blends. The mechanical properties were investigated as a function of the blend composition. The elongation at break and the impact strength increase with increasing SEBS rubber content, whereas the Young's modulus logically decreases proportionally to SEBS amount. Extra addition of SEBS grafted maleic anhydride (SEBS‐g‐MA) induces a synergistic effect. The SEBS‐g‐MA makes it possible to limit the aforementioned rigidity loss and to greatly increase the impact strength. The critical strain energy release rate increases significantly when both reactive and nonreactive rubbers are combined. Three types of microstructures appear depending on the blend composition: (1) small and numerous well‐dispersed particles when reactive rubber is used, (2) about 10 times bigger and less numerous well‐dispersed particles in the case of nonreactive rubber, and (3) a flocculated dispersion of small particles when both reactive and nonreactive rubber are added. Finally, the polyamide performances were significantly increased when the flocculated morphology was noticed due to a better PAXD/SEBS interfacial adhesion given by the SEBS‐g‐MA compatibilization and to a thinner rubber distribution in the matrix. © 2019 Wiley Periodicals, Inc.

AbstractCeramides are known to be involved in various biological processes with their physiological levels elevated in various disease conditions such as diabetes, Alzheimer's, atherosclerosis. To facilitate the rapid screening of Cer d18:1/16:0, d18:1/24:0, d18:1/24:1, d18:1/18:0, d18:1/14:0, d18:1/20:0, and d18:1/22:0 inhibition in HepG2 cells, a RapidFire coupled to tandem mass spectrometry (RF–MS/MS) method has been developed. The RF platform provides an automated solid‐phase extraction system that gave a throughput of 12.6 s per sample to an MS/MS system using electrospray ionization under the positive ion mode. Chromatographic separation of Cer d18:1/16:0, d18:1/24:0, d18:1/24:1, d18:1/18:0, d18:1/14:0, d18:1/20:0, and d18:1/22:0 was achieved using a ternary gradient on C8 type E cartridge. The MS/MS ion transitions monitored were 538.2 → 264.2, 650.7 → 264.2, 648.6 → 264.2, 566.4 → 264.2, 510.4 → 264.2, 594.4 → 264.2, 622.5 → 264.2, and 552.3 → 250.2 for Cer d18:1/16:0, d18:1/24:0, d18:1/24:1, d18:1/18:0, d18:1/14:0, d18:1/20:0, d18:1/22:0, and the internal standard (Cer d17:1/18:0), respectively. The RF–MS/MS methodology showed an excellent performance with an average Z′ value of 0.5–0.7. This is the first report of an RF–MS/MS assay for screening of ceramides which is amenable for high‐throughput screening.

Authors: Shashi  , Centobelli Piera , Cerchione Roberto , Ertz Myriam 
Published: December 2019

AbstractResilience has become a crucial topic in the field of strategic management as it requires companies to design resilient business models to tackle managerial and environmental disruptions of individual firms and supply chains. However, extant research still lacks deep insights into how companies design and manage supply chains according to the resilience principles. With this premise, this paper aims at conducting a state of the art review on supply chain resilience (SCR) considering 125 relevant papers collected from Scopus and Web of Science academic search engine. Starting from the results of the literature review, this study proposes a systemic framework of SCR assessment and contributes to improve the understanding of the impact of different empirically tested constructs on the development of the resilience concept. Further, the findings are summarized in several areas including barriers in developing resilience, metrics to measure the resilience performance, and effective strategies to foster the SCR. Finally, this study outlines promising future research directions for scholars and practitioners.
Business model based on strong sustainability: Insights from an empirical study
Authors: Brozovic Danilo 
Published: December 2019

AbstractThe extant literature on traditional and sustainable business models lacks insights into how strong sustainability—that is, constraining economic and social activities within the limitations of natural resources—can shape business models. Thus, the purpose of this article is to propose a business model framework based on the principles of strong sustainability (SSBM). The proposed framework is developed combining available literature and empirical insights from a qualitative abductive study of 12 permaculture business ventures in Sweden. The results identify nature as the primary stakeholder and recommend strong local anchorage, the creation of diversified income sources, deliberate limitations on economic growth, the infusion of the business model with a systemic and ecosystem perspective, and the design of value flows beyond financial aspects. The discussion reflects on the most important results, provides practical implications and managerial guidelines, and suggests future research in the SSBM.

AbstractIntroductionThe fabellofibular ligament (FFL) is a component of the posterolateral corner (PLC) of the knee and is an anatomically variable static stabilizer. Several investigations have reported prevalence rates for the FFL among their subjects, but no overall prevalence rate has been reported.Materials and MethodsWe conducted a meta‐analysis of all relevant studies reporting prevalence rates of the FFL according to PRISMA and AQUA guidelines and pooled prevalence data using MetaXL 5.3. We also conducted a retroactive magnetic resonance imaging (MRI) study of 100 knees to assess FFL and fabella prevalence.ResultsTwenty‐one studies (from 18 articles) and our MRI data were used in this meta‐analysis (n = 1,176 knees). The pooled prevalence estimate (PPE) for FFL absence was 37.4% (95% confidence interval [CI], 24.5–51.3%). When divided by continent, PPEs of FFL absence were 31.5% (95% CI, 1.4–72.7%), 58.2% (95% CI, 44.1–71.6%), and 29.0% (95% CI, 14.7–45.7%) for North American, European, and Asian subjects, respectively. Cadaveric and MRI studies showed PPEs of FFL absence of 31.5% and 49.7%, respectively. Our MRI results showed PPEs of FFL and fabella absences of 42.0 and 80.0%, respectively.ConclusionsUnderstanding prevalence rates and anatomical geometry of the FFL will assist surgeons in repairing PLC injuries. Our MRI data and previous studies suggest the FFL is frequently present in knees lacking a fabella. Based on the observations of this study, we propose the ligament be renamed the gastrocnemiofibular ligament.

Published: December 2019

AbstractBackgroundBennett lesions represent an extra‐articular ossification on the posteroinferior aspect of the glenoid fossa and a potential source of posterior shoulder pain and limitation. The prevalence of Bennett lesions in the general population is unknown.Materials and methodsA total of 5,662 scapulae from 2,831 individual cadaveric specimens greater than 18 years of age at the time of death were examined. Matching scapulae were evaluated for Bennett lesions by two independent authors. Lesion prevalence was calculated and statistical analysis performed to evaluate differences in prevalence based on specimen sex (males vs. females), ancestry (African‐American vs. Caucasian) and with increasing age at the time of death.ResultsBennett lesions were observed in 3.5% (n = 98 of 2,831) of specimens and 1.8% (n = 104 of 5,662) of scapulae. Interobserver reliability was 0.83, indicating excellent agreement among authors. Males possessed significant higher odds of possessing a Bennett lesion when compared to females (p = .009) and African‐American specimens when compared to Caucasian specimens (p < .001). Each additional year of age was associated with a 1.4% increase in odds of a specimen having a Bennett lesion, while no significant increase in Bennett lesion prevalence was appreciated with increasing specimen age at the time of death when comparing male to female specimens (p = .07) or African‐American to Caucasian specimens (p = .73).ConclusionsBennett lesions were identified in 3.5% of osseous specimens and 1.8% of scapulae, with significantly higher prevalence in male and African‐American specimens.

AbstractMammalian target of rapamycin complex 1 (mTORC1) is evolutionally conserved and frequently activated in various tumors, including colorectal cancer (CRC). It has been reported that the ribosome assembly factor Urb1 acts downstream of mTORC1/raptor signaling and contributes to digestive organ development in zebrafish. Previously, we highlighted that URB1 was overexpressed in CRC. Here, we assessed the mTORC1/regulatory associated protein with mTOR (RAPTOR)‐URB1 axis in CRC tumorigenesis. We found that RAPTOR was overexpressed in CRC tissues and cell lines, was a favorable predictor in patients with CRC, and positively correlated with URB1. Silencing of RAPTOR suppressed CRC cell proliferation and migration and induced cell cycle arrest and apoptosis in vitro and inhibited xenograft growth in vivo. Moreover, ectopic overexpression of RAPTOR exerted an inverse biological phenotype. Knockdown of RAPTOR quenched mTORC1 activity and reduced the expression of URB1 and cyclinA2 (CCNA2). In contrast, overexpression of RAPTOR activated mTORC1 and upregulated URB1 and CCNA2. Furthermore, URB1 and CCNA2 expression were also impeded by rapamycin, which is a specific inhibitor of mTORC1. Thus, RAPTOR promoted CRC proliferation, migration, and cell cycle progression by inducing mTORC1 signaling and transcriptional activation of both URB1 and CCNA2. Taken together, we concluded that RAPTOR has the potential to serve as a novel biomarker and therapeutic target for CRC.
Experimental cake‐baking method applicable to nonchlorinated flour
Authors: Baik Byung‐Kee , Donelson Thomas 
Published: December 2019

AbstractBackground and objectivesApproved Method 10‐90.01, Baking Quality of Cake Flour, requires flour chlorination, which poses safety concerns and is inconvenient. The effects of shortening, sugar, and water proportions on the quality of nonchlorinated flour cakes were determined in order to modify the Approved Method and make it applicable to nonchlorinated flour.FindingsThe reduction of shortening and sugar proportions to 35% and 130% (flour weight basis (fwb)), respectively, increased the center height, center‐to‐edge height (C/E) ratio, and volume of nonchlorinated flour cakes. Nonchlorinated flour cakes baked with 35% shortening (fwb), 130% sugar (fwb), and a fixed 120% (fwb) or optimum water proportion were similar in center height to, and greater in volume than, the chlorinated flour cakes baked according to the Approved Method. The volumes of nonchlorinated flour cakes baked with the modified formula showed significant correlations (p < .05) with those of the corresponding chlorinated flour cakes baked according to the Approved Method.ConclusionsThe Approved Method with modifications of the formula to 35% shortening, 130% sugar, and a fixed water proportion of 120% has the potential to be an effective cake‐baking test applicable to nonchlorinated wheat flour.Significance and noveltyWith no need for chlorination, the modified cake‐baking test delivers improved efficiency in the evaluation of wheat flour quality for making cakes.

AbstractDesmoid‐type fibromatosis following thoracotomy is rare and has been previously reported only in <20 cases; however, it might mimic chest wall recurrence of previous cancer and needs differential diagnosis. When the tumor location corresponded to the thoracotomy incision, we should consider desmoid‐type fibromatosis as a differential diagnosis.
