Published: August 2018

Abstract2D patterns of photothermally responsive near‐infrared (NIR) absorbing gold nanostars (GNS), coated with multiple charged polymer layers, are inkjet‐printed on a glass surface. The shape of the localized surface plasmon resonance (LSPR) NIR absorption bands in the printed patterns loses its peaked form due to plasmon coupling, unless GNS are enveloped in multiple coating layers, keeping the inter‐GNS distance sufficiently large. In the latter case, the photothermal temperature increase (ΔT) induced by the NIR laser irradiation follows a ΔT versus irradiation wavelength (λirr) profile with the same sharply peaked shape of the LSPR bands of the liquid ink. With this result, a new paradigm for inkjet‐writing secure information is introduced, as an alternative to the current methods based on direct visual inspection of printed patterns. While the printed ink patterns of GNS with different coatings are visually indistinguishable despite their different NIR absorption spectrum, their photothermal response changes dramatically with λirr. This allows either to write and read simple information using a single λirr (YES answer for ΔT > threshold) or to use multiple λirr to write and read complex information like thermal bar codes and anti‐counterfeit signatures.
On controller design for systems on manifolds in Euclidean space
Authors: Chang Dong Eui 
Published: August 2018

SummaryA new method is developed to design controllers in Euclidean space for systems defined on manifolds. The idea is to embed the state‐space manifold M of a given control system into some Euclidean space
, extend the system from M to the ambient space
, and modify it outside M to add transversal stability to M in the final dynamics in
. Controllers are designed for the final system in the ambient space
. Then, their restriction to M produces controllers for the original system on M. This method has the merit that only one single global Cartesian coordinate system in the ambient space
is used for controller synthesis, and any controller design method in
, such as the linearization method, can be globally applied for the controller synthesis. The proposed method is successfully applied to the tracking problem for the following two benchmark systems: the fully actuated rigid body system and the quadcopter drone system.
Code phase discrimination function shaping method for Compass B1C QMBOC (6,1,4/33) signal
Authors: Wang Yiwei , Li Wengang 
Published: August 2018

SummaryThe discrimination function shaping method has been proposed to improve the anti‐multipath performance for a global navigation satellite system receiver. However, the existing methods fail to fully exploit the potential anti‐multipath performance of multiplexed binary offset carrier (MBOC)–modulated signals. In this paper, a code phase discrimination function shaping method is proposed for a Compass B1C quadrature MBOC‐modulated signal. The in‐phase binary offset carrier (BOC) (1,1) signal and quadrature‐phase BOC (6,1) signal replicas are designed according to the least squares estimation. Then a shifted cross‐correlation function (CCF) between the in‐phase BOC (1,1) signal and its pseudorandom noise code is multiplied with the obtained CCFs to ensure an unambiguous tracking. Finally, a discrimination function with a small pull‐in range can be obtained by a weighed combination of the in‐phase and quadrature‐phase CCFs. A computer simulation is conducted to assess the performances under multipath and thermal noise conditions.
Analysis of microstructural properties, energy band structure, and defect levels of ZnS films obtained from micro‐controlled SILAR method
Authors: V K Ashith , Rao Gowrish K. 
Published: August 2018

Zinc sulphide (ZnS) thin films were deposited on glass substrate by micro‐controller‐based successive ion layer adsorption and reaction method using ZnCl2 as a precursor. The films were found to be polycrystalline. The crystallite size of the films increased with the increase in both precursor concentration and immersion cycles. The increased crystallite size resulted in the reduction of grain boundary defects which, in turn, improved the electrical properties of the films. The energy band structure of the films was analysed using absorbance and photoluminescence spectra. The films displayed strong absorption for wavelengths less than 400 nm indicating the presence of a wide bandgap with shallow defect levels near the band edges. The bandgap of the films was estimated to be between 3.3 and 3.5 eV. The photoluminescence spectra of the films exhibited a prominent excitonic peak at around 3.33 eV. The defect level emissions were observed at around 3.1, 2.92, 2.76, and 2.64 eV. These emissions were attributed to the transitions from localized zinc and sulphur vacancy levels and interstitial states. An energy band diagram of the films was drawn based on the result of optical and photoluminescence studies.
Mechanistic and Kinetic Study on the Reaction of Thiophene (C4H4S) with O(3P)
Authors: Zhang Yunju , Sun Yuxi , Huang Baomei , Wang Zhiguo 
Published: August 2018

AbstractThe mechanism for the reaction of Thiophene + O(3P) has been investigated using BMC‐CCSD//M06‐2X/6‐311++G(d,p) method in combination with multichannel Rice‐Ramsperger‐Kassel‐Marcus theory and transition‐state theory. The title reaction included three manners, namely, α‐C‐addition, β‐C‐addition, and direct H‐abstraction. The rate constants and branching ratios for eight product channels are calculated. It is predicted that the formation of P1 is dominant at the whole temperature range. The formation of P4+H channel may become competitive at some temperature range. The total rate constants show pressure‐independent, while the individual rate constants were affected by pressure.

Authors: Chakraborty Koushik , Ghosh Surajit , Pal Tanusri 
Published: August 2018

AbstractWe have studied the photo current generation, conduction mechanism and photocatalytic activity in reduced graphene oxide – zinc telluride (RGO‐ZnTe) composite synthesized by simple low‐cost one pot single step solvothermal reaction. The photo responsivity of the RGO‐ZnTe composite thin film photodetector shows 3 orders of magnitude higher compared to controlled‐ZnTe under simulated solar light illumination. A linear variation of photosensitivity with the incident illumination intensity was observed. The electrical conduction measurement of the composite in the frequency range from 20 Hz to 2 MHz was carried out in the temperature range of 298−393 K. The direct current (DC) conductivity of the RGO‐ZnTe composite follows Arrhenius relationship. The scaling of conductivity spectra shows the temperature‐independent nature of the conduction mechanism in the RGO‐ZnTe composite. As prepared RGO‐ZnTe composites exhibit excellent photocatalytic efficiency toward the degradation of Rhodamine B (Rh B) under simulated solar light irradiation in compared to the controlled‐ZnTe. The synergy of ZnTe and RGO in achieving improved photocatalytic Rh B degradation has also been studied.

AbstractThe reactions of InCl3 with Na{Se(CH2)nNMe2} in 1:2 stoichiometry yielded complexes of composition [InCl{Se(CH2)nNMe2}2] (n=2 (1) or 3 (2)). Treatment of Me2InCl with Na(4‐SeC5H4N) afforded [Me2In(4‐SeC5H4N)]n (3). Copper complex [(PEt3)2Cu2(4‐SeC5H4N)2]n (4) was synthesized from CuCl, PEt3 and Na(4‐SeC5H4N). These complexes have been characterized by elemental analysis and NMR spectroscopy. Solid‐state structures of 3 and 4 revealed the formation of one‐ and two‐dimensional co‐ordination polymer which is formed via Se and N atoms of selenolate ligand. Thermal studies of these complexes have been carried out in a furnace or oleylamine to give thin film or nano‐materials of In2Se3, Cu1.8Se and CuInSe2.

Authors: Carta Davide , Dal Prà Matteo , Grazia Ferlin Maria 
Published: August 2018

AbstractThe work describes the synthesis and characterization of a small series of pyrroloquinoline carboxamide derivatives considered on the STX‐0119 model, a known inhibitor of STAT3 (Signal transducers and activators of transcription 3) by interacting with SH2 domain. The scope was to learn SARs and possibly obtain active new compounds for cancer therapy. To this aim, the quinoline scaffold of the lead compound STX‐0119 was modified into the pyrroloquinoline tricycle to obtain two subsets of carboxamide derivatives showing different angular geometry 3H‐pyrrolo[3, 2‐f] and 7H‐pyrrolo[2, 3‐h]quinolines. Successful synthesis of thirty compounds was carried out, adopting methods using both convergent and linear pathways. Amidic coupling chemistry was applied to pyrroloquinoline carboxylic acids to generate the desired carboxamides of aromatic and aliphatic primary and secondary amines. Full physico‐chemical characterization including predicted LogP and LogD of all compounds was accomplished. The biological screening of antiproliferative activity against three human tumor cell lines by MTT test revealed low or no activity.
Nickel Nanoparticles Stabilized by Trisimidazolium Salts: Synthesis, Characterization and Application as Recyclable Catalysts for the Reduction of Nitroarenes
Authors: Fernández Guillem , Sort Jordi , Pleixats Roser 
Published: August 2018

AbstractNickel nanoparticles (Ni NPs) from 10 to 17 nm have been prepared by hydrogenation of Ni(COD)2 (3 bar H2, 70 °C) in the presence of trisimidazolium salts (iodide and tetrafluoroborate). The nanoparticles have been structurally and compositionally characterized by transmission electron microscopy (TEM), high‐resolution (HR) TEM, electron diffraction (ED), energy‐dispersive X‐ray spectroscopy (EDS), X‐ray photoelectron spectroscopy (XPS) and elemental analysis. Magnetic measurements reveal that, as expected, the Ni NPs are superparamagnetic at room temperature. These nanomaterials prove efficient as magnetically recoverable catalysts for the transfer hydrogenation of nitroarenes with hydrazine as hydrogen donor. Their superparamagnetic character also ensures no interparticle aggregation once the external magnetic field is removed.
An improved random forest model of short‐term wind‐power forecasting to enhance accuracy, efficiency, and robustness

Published: August 2018

AbstractShort‐term wind‐power forecasting methods like neural networks are trained by empirical risk minimization. The local optimum and overfitting problem is likely to occur in the model‐training stage, leading to the poor ability of reasoning and generalization in the prediction stage. To solve the problem, a model of short‐term wind power forecasting is proposed based on 2‐stage feature selection and a supervised random forest in the paper. First, in data preprocessing, some redundant features can be removed by a variable importance measure method and intimate samples can be selected based on relevant analysis, so that the efficiency of model training and the correlation degree between input and output samples can be enhanced. Second, an improved supervised random forest (RF) methodology is proposed to compose a new RF based on evaluating the performance of each decision tree and restructuring the decision trees. A new index of external validation in correlation with wind speed in numerical weather prediction has been proposed to overcome the shortcomings of the internal validation index that seriously depends on the training samples. The simulation examples have verified the rationality and feasibility of the improvement. Case studies of measured data from a wind farm have shown that the proposed model has a better performance than the original RF, back propagation neural network, Bayesian network, and support vector machine, in aspects of ensuring accuracy, efficiency, and robustness, and especially if there is high rate of noisy data and wind power curtailment duration in the historical data.

Published: August 2018

ABSTRACTHunting results in direct numerical effects and numerous indirect effects on game species. One indirect effect occurs when a female is killed; and as a consequence, her dependent offspring die, negatively affecting recruitment rates. The mountain lion (Puma concolor) is a hunted species across much of its range. It is almost always illegal to harvest a female with dependent young; however, females frequently travel separately from their kittens, and the occasional unintentional harvest of females with dependent young is unavoidable. We studied the denning periods for female mountain lions in northwest Wyoming, USA, from June 2001 to December 2016, but more intensively between January 2013 and December 2016 with Global Positioning System (GPS) technology. During the intensive period, we measured the amount of time females spent away from the den, distance and time females traveled during each foraging trip, and distance traveled during the entire denning period. We also compared the timing of dens with mountain lion hunting seasons. We recorded parturition dates between 6 June and 4 November. On average, females utilized 4.2 ± 0.5 (SE) dens/denning period, with denning periods persisting 45.8 ± 2.6 (SE) days. The average total distance traveled by females during their 6‐week denning period was 154 km (±18.8 km). On average, females were closest or most likely to be with their kittens at 1600, and furthest from den sites at 0200 and 0600. Utilizing our mean denning period of 46 days, delaying mountain lion hunting until 1 November would avoid the denning period for 85% of dens, and delaying until 1 December would avoid 91% (n = 31). Our research provides information to guide managers in aligning hunting seasons to mitigate orphaning kittens when they are youngest and most vulnerable, and provide hunters the best opportunities to detect and protect dependent young. © 2018 The Wildlife Society.

Background As the use of biologic therapies for the management of knee pathology continues to expand, it is more likely that patients will turn to the Internet to gather information on this topic. Given the lack of scientific consensus on the use of biologics, care providers must understand what information is available online. Questions/Purposes The purpose of this study was to evaluate the quality of websites that patients may use to educate themselves on knee biologics. Methods Websites were identified using search terms relevant to multiple biologic therapies available for knee pathology. Websites were scored based on an author-derived grading rubric, with a total of 25 possible points relating to the role of knee biologics in the diagnosis, evaluation, and treatment of knee pathology. Websites were categorized based on the source (e.g., physician-operated website vs. industry-related website). Reading level was assessed with the Flesch-Kincaid readability test. Results The initial search yielded 375 results, with 96 websites meeting final inclusion criteria. Mean website score was poor, at 6.01 of the 25 possible points (24.0%). Physician websites were the most common, with 60% of the articles identified. Industry-related websites scored the lowest (mean, 3.2 ± 0.97) while hospital-related websites scored the highest (mean, 8.3 ± 2.93). Overall, websites published from hospitals or orthopedic professional societies had significantly higher scores than other websites. The search term “knee PRP” yielded higher-quality results than “knee platelet rich plasma.” Similarly, “knee BMAC” led to better results than “knee bone marrow aspirate concentrate.” The average reading level was 11.4. Conclusion Many online resources are available for patients seeking information about knee biologic therapies, but the quality of websites identified was very poor. Patients should be counseled that the information available online for knee biologic therapy is unreliable. Surgeons should play an increased role in providing resources to patients and educating them on biologic options.
Emotional and cognitive correlates of hating among adolescents: An exploratory study
Authors: Pace Ugo , Passanisi Alessia , D'Urso Giulio 
Published: August 2018

ABSTRACTIntroductionThe phenomenon of hate is becoming common among adolescents, but is little investigated by literature. Typically the haters leave their insults on the victim's social pages to denigrate another person, famous or not. In the literature, to date, there are no scientific studies that have explored psychological variables linked to these behaviors. The aim of this study was to evaluate the psychological correlates of pathological worry and cognitive distortions (CD) related to hating behaviors.MethodsParticipants (202 female and 200 male, mean age 14.9) of this study completed the Hating Adolescents Test (HAT), the Penn State Worry Questionnaire (PSWQ), and the How I Think Questionnaire (HITQ).ResultsPreliminary results show significant gender differences in the variables of the study: on hating and CD “minimizing,” males reported higher scores than females, and females scored higher than males on pathological worry. The mediation model suggests that the CD “assuming the worst” is a mediator in the relationships between pathological worry and hating behaviors.ConclusionsThe study suggests how the tendency towards pathological worry influences hatred among adolescents, but a relevant component is represented by the tendency to distort information and to consider ambiguous situations as hostile. The implications of these findings for future theoretical and empirical research in this field are discussed.
Evolutionary rates of mid-Permian tetrapods from South Africa and the role of temporal resolution in turnover reconstruction

Published: August 2018

AbstractThe Main Karoo Basin of South Africa contains a near-continuous sequence of continental deposition spanning ~80 Myr from the mid-Permian to the Early Jurassic. The terrestrial vertebrates of this sequence provide a high-resolution stratigraphic record of regional origination and extinction, especially for the mid–late Permian. Until now, data have only been surveyed at coarse stratigraphic resolution using methods that are biased by nonuniform sampling rates, limiting our understanding of the dynamics of diversification through this important time period. Here, we apply robust methods (gap-filler and modified gap-filler rates) for the inference of patterns of species richness, origination rates, and extinction rates to a subset of 1321 reliably-identified fossil occurrences resolved to approximately 50 m stratigraphic intervals. This data set provides an approximate time resolution of 0.3–0.6 Myr and shows that extinction rates increased considerably in the upper 100 m of the mid-Permian Abrahamskraal Formation, corresponding to the latest part of theTapinocephalusAssemblage Zone (AZ). Origination rates were only weakly elevated in the same interval and were not sufficient to compensate for these extinctions. Subsampled species richness estimates for the lower part of the overlying Teekloof Formation (corresponding to thePristerognathusandTropidostomaAZs) are low, showing that species richness remained low for at least 1.5–3 million years after the main extinction pulse. A high unevenness of the taxon abundance–frequency distribution, which is classically associated with trophically unstable postextinction faunas, in fact developed shortly before the acme of elevated extinction rates due to the appearance and proliferation of the dicynodontDiictodon. Our findings provide strong support for a Capitanian (“end-Guadalupian”) extinction event among terrestrial vertebrates and suggest that further high-resolution quantitative studies may help resolve the lack of consensus among paleobiologists regarding this event.
Recruiting large online samples in the United States and India: Facebook, Mechanical Turk, and Qualtrics

Published: August 2018

AbstractThis article examines online recruitment via Facebook, Mechanical Turk (MTurk), and Qualtrics panels in India and the United States. It compares over 7300 respondents—1000 or more from each source and country—to nationally representative benchmarks in terms of demographics, political attitudes and knowledge, cooperation, and experimental replication. In the United States, MTurk offers the cheapest and fastest recruitment, Qualtrics is most demographically and politically representative, and Facebook facilitates targeted sampling. The India samples look much less like the population, though Facebook offers broad geographical coverage. We find online convenience samples often provide valid inferences into how partisanship moderates treatment effects. Yet they are typically unrepresentative on such political variables, which has implications for the external validity of sample average treatment effects.

Published: August 2018

AbstractPrimary microcephaly (MCPH) is an autosomal recessive sporadic neurodevelopmental ailment with a trivial head size characteristic that is below 3–4 standard deviations. MCPH is the smaller upshot of an architecturally normal brain; a significant decrease in size is seen in the cerebral cortex. At birth MCPH presents with non-progressive mental retardation, while secondary microcephaly (onset after birth) presents with and without other syndromic features. MCPH is a neurogenic mitotic syndrome nevertheless pretentious patients demonstrate normal neuronal migration, neuronal apoptosis and neural function. Eighteen MCPH loci (MCPH1–MCPH18) have been mapped to date from various populations around the world and contain the following genes:Microcephalin,WDR62,CDK5RAP2,CASC5,ASPM,CENPJ,STIL,CEP135,CEP152,ZNF335,PHC1,CDK6,CENPE,SASS6,MFSD2A,ANKLE2,CITandWDFY3, clarifying our understanding about the molecular basis of microcephaly genetic disorder. It has previously been reported that phenotype disease is caused by MCB gene mutations and the causes of this phenotype are disarrangement of positions and organization of chromosomes during the cell cycle as a result of mutated DNA, centriole duplication, neurogenesis, neuronal migration, microtubule dynamics, transcriptional control and the cell cycle checkpoint having some invisible centrosomal process that can manage the number of neurons that are produced by neuronal precursor cells. Furthermore, researchers inform us about the clinical management of families that are suffering from MCPH. Establishment of both molecular understanding and genetic advocating may help to decrease the rate of this ailment. This current review study examines newly identified genes along with previously identified genes involved in autosomal recessive MCPH.
