Authors: Nitika  , Khanna Rajesh , Kaur Jaswinder 
Published: December 2017

AbstractIn this study, a novel inset‐fed slotted modified T‐shape microstrip patch antenna with DGS is presented. This paper is a demonstration of Differential Algorithm (DE), which is used to optimize the various design parameters of slotted patch antenna in accordance with diverse necessities and scenarios, and also lowers the computation complexity of antenna. The proposed antenna design resonates in two different frequency bands, viz 11.13–11.82 and 15.77–16.89 GHz with their respective bandwidths of 690 and 1120 MHz resonating at 11.47 GHz and 16.27 GHz, respectively. These frequency bands have their application in the field of satellite broadcasting, aeronautical military systems, and radio astronomy corresponding to X and Ku band. The designed antenna has an overall small size of 20 × 11 mm2. The simulated and measured results for the proposed antenna with DE are presented and discussed further.
Design of balanced power divider with wide common‐mode suppression band
Authors: Lee Ching‐Her , Hsu Chung‐I G. , Chen Wen‐Xuan 
Published: December 2017

AbstractIn this paper, a balanced power divider (PD) is designed and implemented in a three‐layer configuration. It consists of two tightly stacked microstrip Wilkinson PDs with a shared ground plane in the middle layer. With both dumbbell‐shaped and partially interdigital open‐ended slots embedded in the common ground, the designed balanced PD can yield a high common‐mode (CM) suppression level over a very wide frequency band without degrading the differential‐mode (DM) performance. A close examination of this design reveals that good CM suppression mainly comes from the blocking of the ground‐plane current path by the open‐ended slots in the ground plane. In addition, the proposed balanced PD also exhibits a very wide CM isolation band. A prototype of the proposed balanced PD is realized. The measured fractional frequency bandwidth for CM suppression is 68% and for CM isolation is 93%.

Published: December 2017

AbstractThis article introduces a direct‐conversion CMOS RF transmitter for the IEEE 802.15.4 standard with a low‐power high‐gain up‐conversion mixer designed in 0.18 μm process. The designed RF direct‐conversion transmitter (DCT) is composed of differential digital to analog converter, passive lowpass filter, quadrature active mixer, and drive amplifier. The most important characteristic in designing RF DCT is to satisfy the 2.4 GHz Zigbee standard in a low power consumption. The quadrature active mixer integrated in the proposed RF DCT provides enough high gain as well as sufficient linearity using a gain boosting technique. The measurement results for the proposed transmitter show very low power consumption of 7.8 mA, output power more than 0 dBm, and adjacent channel power ratio of −30 dBc.

Published: December 2017

AbstractA planar branch‐line coupler with arbitrary power division and harmonic suppression is proposed. A novel offsetting double‐side parallel‐strip T‐section is used for designing the coupler. To verify the design procedure, a prototype operating at 1.76 GHz with 10 dB power division ratio and a stopband up to nearly four times of the center frequency is simulated, fabricated and tested. The measured results agree well with the simulated ones.
Bandwidth enhancement of a slot antenna with an open stub
Authors: Kim Jae Hee , Ahn Chi‐Hyung , Chun Joong‐Chang 
Published: December 2017

AbstractA method to increase the bandwidth of a slot antenna is proposed. Slot antennas are not widely used in mobile terminals because they have narrower bandwidth than conventional inverted F antennas. To increase the bandwidth, in this letter, a stub with one end connected to ground is inserted into the slot. The stub resonance is combined with the existing slot resonance and widens the antenna bandwidth. It is important to impedance matching at resonant frequencies of both slot and stub when feeding the antenna. For this sake an inductor and a capacitor are connected in series with feed line. The bandwidth and efficiency of the proposed antenna are compared with those of the conventional antenna for the same slot size. The proposed antenna has an impedance bandwidth of 531 MHz, while the conventional antenna has a bandwidth of 165 MHz at 2.4 GHz for S11 < −10 dB. Moreover, the bandwidth more than 70% efficiency is 230 MHz (2.3 GHz–2.53 GHz) for the proposed antenna, while it is 510 MHz (2.3 GHz–2.81 GHz) for the proposed antenna.
Members of the abscisic acid co‐receptor PP2C protein family mediate salicylic acid–abscisic acid crosstalk

Published: December 2017

AbstractThe interplay between abscisic acid (ABA) and salicylic acid (SA) influences plant responses to various (a)biotic stresses; however, the underlying mechanism for this crosstalk is largely unknown. Here, we report that type 2C protein phosphatases (PP2Cs), some of which are negative regulators of ABA signaling, bind SA. SA binding suppressed the ABA‐enhanced interaction between these PP2Cs and various ABA receptors belonging to the PYR/PYL/RCAR protein family. Additionally, SA suppressed ABA‐enhanced degradation of PP2Cs and ABA‐induced stabilization of SnRK2s. Supporting SA's role as a negative regulator of ABA signaling, exogenous SA suppressed ABA‐induced gene expression, whereas the SA‐deficient sid2‐1 mutant displayed heightened PP2C degradation and hypersensitivity to ABA‐induced suppression of seed germination. Together, these results suggest a new molecular mechanism through which SA antagonizes ABA signaling. A better understanding of the crosstalk between these hormones is important for improving the sustainability of agriculture in the face of climate change.

Published: December 2017

BackgroundAlmost all men who present with advanced prostate cancer (CaP) and some men who fail therapy for clinically localized CaP are treated with androgen deprivation therapy (ADT). CaP cell lines are used to identify and characterize new agents for ADT or investigate mechanisms of ADT resistance. CaP cell lines are maintained in culture medium that contains fetal bovine serum, which contains testosterone (T). Androgen deprivation experiments are performed using media supplemented with androgen‐free serum, such as charcoal stripped fetal bovine serum (CS‐FBS). However, CS‐FBS composition varies from batch‐to‐batch and variations may impact experimental reproducibility. Serum free media (SFM) may provide a better defined alternative to media supplemented with CS‐FBS (CSM).MethodsCell growth of six human CaP cell lines was assessed using 3‐(4,5‐Dimethylthiazol‐2‐yl)‐2,5‐diphenyltetrazolium bromide (MTT). Androgen levels were measured using liquid chromatography‐tandem mass spectrometry (LC‐MS/MS).ResultsMTT assays showed 5 of 6 CaP cell lines grew after 6 days of culture in androgen‐ deprived SFM or CSM. LNCaP and VCaP growth was stimulated when cells were cultured in SFM or CSM supplemented with T. LNCaP, C4‐2, LAPC‐4, and VCaP cell growth was inhibited when cultured in SFM or CSM with T and bicalutamide. LC‐MS/MS data showed LAPC‐4 cells produced similar DHT levels when cultured in T‐supplemented SFM or CSM. Dutasteride impaired T to DHT metabolism in LAPC‐4.ConclusionsMedia composition contributed to growth differences observed between CaP cells cultured in SFM or CSM. However, the differences in media composition did not impair CaP cell response to T‐stimulated growth, bicalutamide growth inhibition, metabolism of T, or dutasteride efficiency. SFM can be used as a better defined alternative to CSM for androgen deprivation experiments.

Published: December 2017

AbstractBACKGROUNDThe diamondback moth Plutella xylostella (L.) is the most widely distributed pest of cruciferous crops and has developed resistance to most commonly used insecticides, including chlorantraniliprole. Resistance to chlorantraniliprole is likely caused by mutations of the target, the ryanodine receptor, and/or mediated by an increase in detoxification enzyme activities. Although target‐site resistance is documented in detail, resistance mediated by increased metabolism has rarely been reported.RESULTSThe activity of cytochrome P450 was significantly higher in two resistant P. xylostella populations than in a susceptible one. Among ten detected cytochrome P450 genes, CYP6BG1 was significantly overexpressed (over 80‐fold) in a field‐resistant population compared with expression in a susceptible one. Knockdown of CYP6BG1 by RNA interference dramatically reduced the 7‐ethoxycoumarin‐O‐deethylase (7‐ECOD) activity of P450 by 45.5% and increased the toxicity of chlorantraniliprole toward P. xylostella by 26.8% at 48 h postinjection of double‐stranded RNA. By contrast, overexpression of CYP6BG1 in a transgenic Drosophila melanogaster line significantly decreased the toxicity of the insecticide to the transgenic flies.CONCLUSIONSOverexpression of CYP6BG1 may contribute to chlorantraniliprole resistance in P. xylostella. Our findings will provide new insights into the mechanisms of resistance to diamide insecticides in other insect pests. © 2017 Society of Chemical Industry

Published: December 2017

AbstractCuCr2O4/reduced graphene oxide (rGO) composites were prepared using a two‐step method. Detailed characterizations of the material were performed with X‐ray diffraction (XRD), Zeta potential, Fourier transform infrared (FT‐IR), transmission electron microscopy (TEM), X‐ray photoelectron spectroscopy (XPS), Raman spectra, and Thermal Gravimetric Analyzer (TGA). The characterizations showed that the ∼50 nm CuCr2O4 nanoparticles were successfully supported on the rGO via static electricity. The TGA results showed that the quality of rGO in composites was around 10%. The experimental results showed that the catalysts obtained high catalytic activity for the selective oxidation of cyclohexane to cyclohexanone with H2O2. The catalyst obtained a conversion rate of cyclohexane of up to 95.8%. 78.1% cyclohexanone selectivity was obtained. The catalyst had good cycling stability after 5 reuses. Compared to the other composite materials, the catalyst had high catalytic activity for the selective oxidation of cyclohexane to cyclohexanone.

Published: November 2017

AbstractBackgroundDeveloping countries face the highest incidence of trauma, and on the other hand, they do not have resources for mitigating the scourge of these injuries. The World Health Organization through the Essential Trauma Care (ETC) project provides recommendations for improving management of the injured and building up of systems that are effective in low–middle‐income countries (LMICs). This study uses ETC project recommendations and other trauma‐care guidelines to evaluate the current status of the resources and organizational structures necessary for optimal trauma care in Botswana; an African country with relatively good health facilities network, subsidized public hospital care and a functioning Motor Vehicle Accident fund covering road traffic collision victims.MethodA cross‐sectional descriptive design employed convenience sampling for recruiting high‐volume trauma hospitals and selecting candidates. A questionnaire, checklist, and physical verification of resources were utilized to evaluate resources, staff knowledge, and organization‐of‐care and hospital capabilities. Results are provided in plain descriptive language to demonstrate the findings.ResultsNecessary consumables, good infrastructure, adequate numbers of personnel and rehabilitation services were identified all meeting or exceeding ETC recommendations. Deficiencies were noted in staff knowledge of initial trauma care, district hospital capability to provide essential surgery, and the organization of trauma care.ConclusionThe good level of resources available in Botswana may be used to improve trauma care: To further this process, more empowering of high‐volume trauma hospitals by adopting trauma‐care recommendations and inclusive trauma‐system approaches are desirable. The use of successful examples on enhanced surgical skills and capabilities, effective trauma‐care resource management, and leadership should be encouraged.

The steady motion of a closely fitting vesicle in a tube
Authors: Barakat Joseph M. , Shaqfeh Eric S. G. 
Published: November 2017

A singular perturbation theory is developed for the steady, inertialess motion of a lipid-bilayer vesicle flowing through a narrow tube. The vesicle is treated as a sac of fluid enclosed by an inextensible membrane that admits a bending stiffness. Matched asymptotic expansions are developed in terms of a clearance parameter $\unicode[STIX]{x1D716}\ll 1$ in order to calculate the flow field and vesicle shape. Mild restrictions are applied to the ratio of viscosities $\unicode[STIX]{x1D705}$ and the ratio of bending stresses to viscous stresses $\unicode[STIX]{x1D6FD}$; in particular, the theory holds for $\unicode[STIX]{x1D705}=o(\unicode[STIX]{x1D716}^{-1/2})$ and $\unicode[STIX]{x1D6FD}=O(\unicode[STIX]{x1D716}^{-1})$. The ratio of the vesicle length to the tube radius $\ell$ is included as a parameter and asymptotic solutions in the limit of negligible bending stiffness are developed for long, cylindrical vesicles and short, spherical vesicles. The main result of the theory is a prediction for the vesicle speed and extra pressure drop due to the presence of the vesicle in the tube. The effects of confinement, vesicle length, and membrane bending elasticity are examined. The theoretical predictions show good agreement with experimental measurements reported for vesicles and red blood cells in highly confined channel flow. Previously reported models for red blood cells (Secomb et al., J. Fluid Mech., vol. 163, 1986, pp. 405–423; Halpern & Secomb, J. Fluid Mech., vol. 203, 1989, pp. 381–400) are clarified and extended in light of the new theory.
Flow separation control behind a cylindrical bump using dielectric-barrier-discharge vortex generator plasma actuators
Authors: Vernet Julie A. , Örlü Ramis , Alfredsson P. Henrik 
Published: November 2017

Dielectric-barrier-discharge plasma actuators are arranged to produce counter-rotating streamwise vortices to control flow separation on a cylindrical bump on a flat plate that is approached by a turbulent boundary layer. The control was tested for different free-stream velocities and actuation driving voltages. The recirculation area downstream of the bump was reduced by the actuation for velocities up to $15~\text{m}~\text{s}^{-1}$ at the highest voltage achievable of the present set-up. However, the flow shows a bi-modality, the nominal two-dimensional wake flow is shown to consist of large-scale streamwise vortices, which are energised by the actuation until a phenomenon of lock-on of these vortices occurs at sufficiently high driving voltages. The wavelength of the actuation is half that of the large-scale vortices. The lock-on shifts sometimes, i.e. the large streamwise vortices centre switch spanwise location, explaining the bi-modality in the flow. The details of the bi-modality are further investigated by conditional averaging and proper orthogonal decomposition.
Oral Hygiene Therapy Assists in Behavioural Intervention for Smoking Cessation: A Pilot Approach for Oral Health Care Providers
Authors: Furgeson Danielle , Wang Chin-Wei (Jeff) 
Published: November 2017

Introduction: Behavioural dependency, such as oral and hand fixation, can hinder cessation efforts when nicotine replacement therapy is used as a stand-alone intervention. We here present a case report of one of several patients who has successfully achieved smoking cessation utilizing oral hygiene therapy (OHT).Case description: The patient is a 52-year-old male with a 25-year smoking habit of two packs daily. Previous attempts at smoking cessation were unsuccessful with various nicotine replacement therapies (NRTs). After introducing interdental cleaning device and modifying tooth-brushing techniques during oral hygiene therapy, the patient reported frequent use of toothpaste and using the device to satisfy his oral-hand fixation to successfully quit smoking.Conclusion: Oral hygiene therapy may enhance smoking cessation in select patients who are more behavioural dependent than nicotine dependent. Future studies are needed to develop evidence-based individualized intervention to include OHT as part of the interdisciplinary approach for smoking cessation.

AbstractAlcoholic patients are more susceptible toStrongyloides stercoralisinfection. The chronic use of alcohol raises the levels of endogenous corticosteroids, which regulates the development of larvae and stimulates the differentiation of rhabditiform into infective filariform larvae, thus inducing internal autoinfection. Therefore, early diagnosis is important to prevent severe strongyloidiasis. The aim of this study was to evaluate the efficacy of parasitological methods, according to the parasite load and the number of stool samples, for diagnosis ofS. stercoralisinfection, as well the peripheral blood eosinophil count in alcoholic patients. A total of 330 patients were included in this study. The diagnosis was established using three parasitological methods: agar plate culture, Baermann–Moraes method and spontaneous sedimentation. Peripheral eosinophilia was considered when the level was >600 eosinophils/mm3. The agar plate culture (APC) had the highest sensitivity (97.3%). However, the analysis of multiple samples increased the sensitivity of all parasitological methods. The sensitivities of the methods were influenced by the parasite load. When the larval number was above 10, the sensitivity of APC was 100%, while in spontaneous sedimentation the sensitivity reached 100% when the larval number was above 50. In the present study, 15.4% of alcoholic patients infected withS. stercoralis(12/78) had increased peripheral blood eosinophil count (above 600 eosinophils/mm3). For an efficient parasitological diagnosis ofS. stercoralisinfection in alcoholic patients, repeated examination by two parasitological methods must be recommended, including agar plate culture due to its higher sensitivity. Moreover,S. stercoralisinfection was associated with eosinophilia, mostly in patients excreting up to 10 larvae/g faeces.
Divine Hiddenness: Defeated Evidence
Authors: Anderson Charity 
Published: November 2017

AbstractThis paper challenges a common assumption in the literature concerning the problem of divine hiddenness, namely, that the following are inconsistent: God's making available adequate evidence for belief that he exists and the existence of non-culpable nonbelievers. It draws on the notions of defeated evidence and glimpses to depict the complexity of our evidential situation with respect to God's existence.
Cross-Informant Disagreement on Behavioral Symptoms in Adolescent	Attention-Deficit/Hyperactivity Disorder and Its Impact on Treatment	Effects
Authors: Hennig Timo , Schramm Satyam Antonio , Linderkamp Friedrich 
Published: November 2017

Abstract. In assessing adolescent behavior difficulties, parents, teachers, and the adolescents themselves are key informants. However, substantial disagreement has been found between informants. Specifically, children with attention-deficit/hyperactivity disorder (ADHD) tend to overestimate their competencies, also known as “positive (illusionary) bias.” This study compared parent, teacher, and adolescent ratings of ADHD and other behavioral symptoms in a sample of 114 adolescents with ADHD. Further, the effect of cross-informant disagreement (CID) on treatment outcomes was investigated in a subsample of 54 adolescents who had undergone a training and coaching intervention. Overall, there was moderate agreement among informants. Parent and adolescent ratings were more strongly correlated with each other than with teacher ratings. The strongest discrepancy was found between teacher and adolescent ratings on prosocial behavior. This discrepancy explained 12% of the variance in parent-rated ADHD symptom severity after the intervention. The treatment was less effective in participants with high teacher-adolescent disagreement on prosocial behavior (d = 0.41) than with low disagreement (d = 0.98). These findings suggest that professionals working with adolescents with ADHD should consider multiple sources of information before initiating treatment and pay attention to cross-informant disagreements because these may indicate a risk of diminished treatment effects.

Published: November 2017

Abstract. The Inventory of Callous and Unemotional Traits (ICU) was developed to measure callous-unemotional (CU) psychopathic traits in children and adolescents. Studies that have examined the factor structure of ICU showed considerable controversy. The aim of this study was to examine the factor structure and psychometric proprieties of the Portuguese translation of the ICU. A total of 1,011 children and adolescents (495 boys and 516 girls), mean age of 13.36 years, participated in this study. Exploratory factor analysis produced two factors: uncaring and callousness; Cronbach’s α for each of the factor was .83 and .79 for the total score. Significant main gender and interaction between gender and age effects were found; girls reported lower CU traits than boys; children reported higher CU traits compared to preadolescents and adolescents, particularly in boys. CU also correlated with emotional symptoms, conduct problems, and psychosocial impairment. Furthermore, CU traits related to conduct problems both in boys and in girls, although this relationship was higher for boys. To conclude, findings of the present study showed that the Portuguese version of the ICU seems to be a reliable and valid instrument to assess CU traits among children and adolescents in Portugal. However, the original 3-factor model was not supported.
