Published: October 2018

BackgroundAdamantinomas are rare bone tumors, commonly affecting the tibia. Due to the rare nature of disease, previous studies are small or from multiple centers. The purpose of this study is to investigate outcomes of patients with adamantinoma treated in a single institution.MethodsForty‐six histological confirmed adamantinomas of the extremities were reviewed at our institution between 1939 and 2012. Follow‐up data included clinical and radiographical information focusing on complications, local recurrence, metastasis, and overall survival after the treatment. The mean follow‐up was 16 years (range 2‐42 years).ResultsThe most common location was the tibia (n = 31). Patients commonly presented with pain and swelling. The mean age was 24 years (7‐79 years). Thirty‐seven patients were treated with limb salvage. The 39% of patients required a reoperation. The 10‐year disease specific‐ and recurrence free survival was 92% and 72%, with three patients having a recurrence over 15 years postoperative. Older (> 20 years) patients and males were at increased risk of local recurrence (P < 0.05).ConclusionTreatment of adamantinoma of the long bone consists of limb‐salvage surgery. Male patients should be cautioned on their increased risk of disease recurrence, and advocate for continued surveillance of patients even greater than 15‐years postoperatively due to late tumor recurrence.

Published: October 2018

Background and ObjectivesLittle is known regarding the difference in prognosis among patients who have an incidentally discovered adrenocortical carcinoma (ACC) vs those who present with signs or symptoms. We aimed to explore differences in the outcomes of these two populations.MethodsData were collected on patients who underwent resection of ACC at 1 of 13 institutions between January 1993 and December 2014. Presentations were categorized as incidental vs symptomatic and outcomes were compared.ResultsAmong 227 patients, 100 were diagnosed incidentally while 127 patients presented with symptoms/signs. Clinical and pathological features were comparable among incidental vs nonincidental patients with ACC following the exceptions. Patients with incidentalomas were more likely to have a T1/T2 tumor (55.8% vs 34.8%;
P < 0.01) and less likely to have a functional tumor (33.7% vs 47.9%;
P = 0.04). Patients with an incidental ACC had improved median recurrence‐free survival (RFS; 29.4 months) compared with patients with a nonincidental ACC (13.0 months;
P = 0.03); however, on multivariable analysis, incidental ACC was not an independent predictor of survival.ConclusionsPatients with resected ACC identified incidentally had an improved RFS compared with the patients who presented with symptoms or signs. This difference may be related to the patients with incidental tumors having earlier T‐stage disease.

Published: October 2018

Objectives/HypothesisIntraoperative recording devices are being increasingly used to provide video for contemporary surgical training. The objective of this study was to evaluate the use of a smartphone as a low‐cost alternative to obtain high‐resolution video from the surgeon's perspective.Study DesignA study evaluating the feasibility of using a head‐mounted smartphone with a telephoto lens for point‐of‐view surgical videography.MethodsVideo recordings of a rhinoplasty procedure were taken using a head‐mounted smartphone and two handheld cameras, a Canon Powershot SD1400 IS and a Sony HandyCam HDR‐CX160. Video clips were shown to 16 blinded otolaryngology residents (n = 10) and attending physicians (n = 6) for individual video evaluation using a Likert scale (1 being poor quality, 5 being excellent quality). In addition, the study participants were asked to select which video clip they preferred when presented to them side by side.ResultsThe iPhone 7 was given the highest overall mean video quality rating of 3.9 ± 0.57 and was preferred over the two handheld cameras by nearly all surveyed surgeons. The Canon Powershot SD1400 IS was given a mean rating of 3.3 ± 1.0 and preferred over the SonyHandyCam HDR‐CX160 by all surgeons. The Sony HandyCam HDR‐CX160 was given a mean rating of 1.5 ± 0.13.ConclusionsA head‐mounted smartphone equipped with a telephoto lens provides a novel method to intraoperative surgical recording. The design is simple, low cost, and allows the surgeon to capture fine anatomical detail from the desirable point‐of‐view perspective.Level of EvidenceNA Laryngoscope, 129:578–581, 2019

Published: October 2018

Objectives/HypothesisWe aimed to investigate if vascular endothelial growth factor (VEGF) and other angiogenic and inflammatory factors correlated with the clinical presentation in hereditary hemorrhagic telangiectasia (HHT) patients, particularly in regard to the severity of epistaxis.Study DesignProspective, comparative, single‐center study.MethodsOne hundred nine samples were collected from 75 HHT patients attending the ear, nose, and throat department at Oslo University Hospital from February 2012 to August 2013. For comparison, samples were collected from 16 healthy controls. Angiogenic and inflammatory factors related to endothelial cell activation were analyzed by enzyme immunoassays. The grade of epistaxis was evaluated using the Epistaxis Severity Score and epistaxis Intensity, Frequency, and Need for Blood Transfusion score at the day of blood sampling. The presence of internal organ manifestations in the HHT group was recorded.ResultsPentraxin 3 (PTX3) was the only factor that was significantly higher in the HHT patients than the controls and showed significant correlation to the epistaxis severity grade and the hemoglobin level. The VEGF level was higher in the HHT patients compared to controls but not to a significant degree. In addition, a significant correlation of the level of VEGF and the grade of epistaxis could not be observed. Also, no significant correlations were observed between the presence of internal organ manifestations and the level of angiogenic factors.ConclusionsPTX3, at least partly reflecting vascular inflammation, can be a potential biomarker for the severity of HHT associated epistaxis. The serum level of VEGF was not correlated with the severity of epistaxis in the HHT patients.Level of Evidence2 Laryngoscope, 129:E44–E49, 2019

Authors: Akram Ali , Pişcoran Laurian‐Ioan 
Published: October 2018

AbstractThe main objective of this paper is to study the warped product pointwise semi‐slant submanifolds which are isometrically immersed into Sasakian manifolds. First, we prove some characterizations results in terms of the shape operator, under which influence a pointwise semi‐slant submanifold of a Sasakian manifold can be reduced to a warped product submanifold. Then, we determine a geometric inequality for the second fundamental form regarding to intrinsic invariant and extrinsic invariant using the Gauss equation instead of the Codazzi equation. Evenmore, we give some applications of this inequality into Sasakian space forms, and we will investigate the status of equalities in the inequality. As a particular case, we provide numerous applications of the Green lemma, the Laplacian of warped functions and some partial differential equations. Some triviality results for connected, compact warped product pointwise semi‐slant submanifolds of Sasakian space form by means of Hamiltonian and the kinetic energy of warped function involving boundary conditions are established.
The effects of power on consumers’ evaluation of a luxury brand's corporate social responsibility

Published: October 2018

AbstractThis paper examines how power affects consumers’ responses to corporate social responsibility (CSR) initiatives of luxury brands. The results of three studies show that high‐power individuals evaluated a luxury brand's CSR campaign more positively than low‐power individuals. High‐power individuals viewed CSR activities as being more fluent than low‐power individuals. This study further demonstrates that power influences consumers’ responses to nonluxury brand's CSR activities. Low‐power individuals, who are more receptive to warmth, evaluated nonluxury brand's CSR more favorably rather than high‐power individuals.
Ligninolytic enzymes: Versatile biocatalysts for the elimination of endocrine‐disrupting chemicals in wastewater

Published: October 2018

AbstractDirect municipal wastewater effluent discharge from treatment plants has been identified as the major source of endocrine‐disrupting chemicals (EDC) in freshwaters. Consequently, efficient elimination of EDC in wastewater is significant to good water quality. However, conventional wastewater treatment approaches have been deficient in the complete removal of these contaminants. Hence, the exploration of new and more efficient methods for elimination of EDC in wastewater is imperative. Enzymatic treatment approach has been suggested as a suitable option. Nonetheless, ligninolytic enzymes seem to be the most promising group of enzymes for EDC elimination, perhaps, owing to their unique catalytic properties and characteristic high redox potentials for oxidation of a wide spectrum of organic compounds. Therefore, this paper discusses the potential of some ligninolytic enzymes (laccase, manganese peroxidase, and versatile peroxidase) in the elimination of EDC in wastewater and proposes a new scheme of wastewater treatment process for EDC removal.

AbstractBackgroundEarly‐onset Parkinson's disease (PD) is the most common inherited form of parkinsonism, with the PRKN gene being the most frequently identified mutated. Exon rearrangements, identified in about 43.2% of the reported PD patients and with higher frequency in specific ethnicities, are the most prevalent PRKN mutations reported to date in PD patients.MethodsIn this study, three consanguineous families with early‐onset PD were subjected to whole‐genome sequencing (WGS) analyses that were followed by Sanger sequencing and droplet digital PCR to validate and confirm the disease segregation of the identified genomic variations and to determine their parental origin.ResultsFive different PRKN structural variations (SVs) were identified. Because the genomic sequences surrounding the break points of the identified SVs might hold important information about their genesis, these were also characterized for the presence of homology and repeated sequences.ConclusionWe concluded that all identified PRKN SVs might originate through retrotransposition events.

Authors: Deng Jing‐Ya , Yao Jiao , Sun Dong‐Quan , Guo Li‐Xin 
Published: October 2018

AbstractA MIMO antenna with 10 elements operating on 3.3‐3.6 GHz for 5G applications is proposed. The 10 elements of the proposed MIMO antenna include six monopoles and four slots with coupled feed. The monopoles and slots are alternately placed along the four sides of the mobile terminal with different radiating modes. The antenna is printed on a planar substrate, resulting in low cost and easy fabrication. The antenna is simulated, fabricated, and measured, the isolations are better than 11 dB, the efficiencies are about 50‐76%. The envelop correlation coefficient (ECC) is lower than 0.15 between any two antenna elements, and the calculated channel capacity is reached about 48‐51 bps/Hz, which is 7 bps/Hz lower than the ideal 10 × 10 MIMO channel.

Published: October 2018

AbstractA dual‐band frequency reconfigurable multiple‐input multiple‐output (MIMO) antenna system is presented. The design consists of two slot‐based antenna elements made on an FR4 board and occupies an area of 50 × 100 mm2. The antenna operates in two bands. Further, a varactor diode is integrated across the slot to achieve the frequency reconfiguration. The antenna can be reconfigured to operate in both bands from 1.35‐1.62 GHz and 1.95‐2.2 GHz with minimum −6 dB bandwidth of 50 MHz. A defected ground structure (DGS) between the antenna elements is used to improve the isolation. With compact size and low envelope correlation coefficient (ECC), the design is suitable for long‐term evolution (LTE) systems and cognitive radio (CR) enabled platforms.

Published: October 2018

AbstractA compact broadband ambient RF energy harvester operating from 1800 MHz up to 2.5 GHz is proposed in this paper. This work is motivated by the huge amount of free and continuously available RF energy in the surroundings that can be utilized into useable energy. Harvest performance is investigated using two antennas in this work, a circular polarized and an array antenna. Due to low ambient power densities, a multistage rectifier is utilized to improve the output dc voltage of the proposed system. Measurements indicate the system is capable of harvesting up to 1.8 Vdc output from nondedicated ambient RF energy sources in an urban area, which is significant in the absence of other energy sources.

AbstractObjectiveThe aim of this study is to evaluate the diagnostic utility of prenatal diagnosis using the chromosomal microarray analysis (CMA) for fetuses presenting with isolated or associated intrauterine growth restriction (IUGR).MethodWe retrospectively included all fetuses with IUGR referred for prenatal testing and studied by rapid fluorescence in situ hybridization (FISH), karyotype, and CMA.ResultsAmong the 162 IUGR fetuses (78 associated and 84 isolated IUGR) included, 15 had an abnormal FISH result: 10 associated and five isolated fetal IUGRs. Among the 143 fetuses studied by CMA, 10 (7%) presented pathogenic copy number variations (CNVs). All 10 were in the associated fetal IUGR group (10/65 or 15.4%; 95% confidence interval [CI]: 8.4%‐26.2%) versus 0/78 in the isolated fetal IUGR group (95% CI: 0%‐5.6%). Six fetuses (4.2%) carried variants of unknown significance (VOUS) (three associated and three isolated fetal IUGRs).ConclusionOur study highlights the added value of CMA in the case of associated fetal IUGR with an incremental yield of 6.1% (4/65) over karyotyping. No pathogenic CNVs were reported in the isolated fetal IUGR group. More studies must be conducted to determine when and whether CMA would be wisely indicated in this population.
Multi‐manipulators coordination for bilateral teleoperation system using fixed‐time control approach
Authors: Yang Y. , Hua C. , Guan X. 
Published: October 2018

SummaryIn this paper, the fixed‐time synchronization control problem for bilateral teleoperation system composed of a single master manipulator and multiple cooperative slave manipulators with system uncertainties and external disturbances is addressed. The multiple cooperative slave manipulators have the capability to perform some complex tasks that are difficult or even impossible to be executed by a single slave manipulator. In order to control the multiple slave manipulators handling a common object with faster speed and higher accuracy, a new adaptive neural networks (NNs)–based fixed‐time control scheme is proposed. First, under the assumptions that the slave manipulators are rigidly grasping a nondeformable object, an integrated dynamic model composed of multiple slave manipulators and an object is derived. The object's grasping forces are concealed in the derived dynamics and can be controlled independent of the motion space. Then, a new nonsingular integral terminal sliding mode providing fixed‐time convergence of the velocity and position errors is designed with high‐degree terms and lower‐degree terms. By setting proper initial value of the integral function, the system settling time will be reduced greatly. Moreover, the corresponding adaptive NN‐based fixed‐time control approach is proposed by employing the strong approximation of the NNs. It is proved that the closed‐loop teleoperation system is semiglobally fixed‐time stable and the synchronization errors between the local manipulator and the object will converge to zero in fixed time for any initial condition of the master and the slaves. Finally, simulation and experiment are both performed to verify the effectiveness of the proposed method.

Published: October 2018

SummaryThis paper considers the boundary control problem for linear stochastic reaction‐diffusion systems with Neumann boundary conditions. First, when the full‐domain system states are accessible, a boundary control is designed, and a sufficient condition is established to ensure the mean‐square exponential stability of the resulting closed‐loop system. Next, when the full‐domain system states are not available, an observer‐based control is proposed such that the underlying closed‐loop system is stable. Furthermore, observer‐based controller is designed for the systems with anH∞performance. Simulation examples are given to demonstrate the effectiveness and potential of the new design techniques.
The Nature and Measurement of Children's Early Composing
Authors: Quinn Margaret F. , Bingham Gary E. 
Published: October 2018

AbstractYoung children's writing development (i.e., writing occurring in preschool and kindergarten prior to the skilled, fluent writing associated with formal schooling) is an important predictor of later literacy achievement. Current policy movements, such as the Common Core State Standards, invoke increased composing demands, yet research has often focused on children's growing ability to transcribe (e.g., form letters, spell words) rather than their ability to compose text and generate ideas. The current study examined literature from the past 30 years to determine the prevailing operational definitions of early composing and the ways in which composing has been measured to date. Given inclusion criteria, the authors collected and coded articles to determine trends and prevailing approaches (n = 445). Findings revealed that various theoretical and conceptual frames influenced approaches to assessing children's composing, yielding little shared understanding of the nature and development of early composing. Findings also revealed that tasks used to measure children's early composing development have not always aligned with theoretical notions of early writing, nor have they been properly operationalized in psychometrically sound, valid, and reliable ways. Further, analyses of trends across time yielded insight into the evolving conceptualizations and prioritization of particular aspects of early composing, such as the focus on children's use of conventional encoding in a composing task context. Implications for practice are discussed in light of these findings.

AbstractInfertile women often experience chronic stress, which may have a negative impact on general well‐being and may increase the burden of infertility. In this open‐label, parallel, randomized controlled trial, infertile women aged 18–50 years (median 37 years) were assigned to an 8‐week mindfulness‐based program (MBP) or no intervention. The primary outcome was stress severity measured by the Lipp's Stress Symptoms Inventory (ISSL). Data were analyzed by modified intent‐to‐treat principle, which included all cases available to follow‐up regardless of adherence to the intervention (62 participants from the MBP group and 37 from the control group). The median number of symptoms of chronic stress recorded in the past month decreased from six (interquartile range 2 to 9) before the MBP to two (interquartile range 1 to 4) after the intervention (p < 0.001, repeated measures analysis of variance with Time × Group interaction). Depressive symptoms also decreased after MBP, whereas general well‐being improved (p < 0.01 for both outcomes). Hair cortisol and serum brain‐derived neurotrophic factor (BDNF) did not change significantly between preintervention and postintervention. None of the outcomes changed significantly in the control group. MBP was effective in reducing stress and depressive symptoms while increasing general well‐being in infertile women.
Superconformal index of higher derivative $$ \mathcal{N}=1 $$ multiplets in four dimensions
Authors: Beccaria Matteo , Tseytlin Arkady A. 
Published: October 2018

AbstractSupersymmetric partition function of$$ \mathcal{N}=1 $$N=1superconformal theories onSβ1 × S3is related to the superconformal index receiving contributions from short representations. The leading coefficients in the smallβ(high “temperature”) expansion of the index were previously related to the conformal anomaly coefficients of the theory. Assumptions underlying universality of these relations were tested only for simplest low-spin unitary multiplets. Here we consider examples of higher derivative non-unitary$$ \mathcal{N}=1 $$N=1multiplets that naturally appear in the context of extended conformal supergravities and compute their superconformal index. We compare the coefficients in the smallβexpansion of the index with those proposed earlier for unitary multiplets and suggest some modifications that should apply universally to all types of theories. We also comment on the structure of subleading terms and the case of$$ \mathcal{N}=4 $$N=4conformal supergravity.
