Abstract Large‐area α‐MnO 2 nanoflower arrays are synthesized by using a facile and template‐free electrochemical deposition on flexible graphite paper. These exhibit high specific capacitance of 314 F g −1 at current density 1 A with remarkable rate capability (61.1 % retention 40 ) excellent cycle stability. Furthermore, the fabricated symmetric supercapacitor also displays good performance flexibility.
In the medical industry, minimizing biofouling is of utmost importance as it helps to reduce bacterial adhesion and prevent cross-infection. this study, cyclized/knotted polydivinylbenzene (PDVB), a polymer with distinctive structural features, proposed for first time be utilized in preparation antibacterial coatings. Firstly, (PDVB) synthesized via deactivation-enhanced atom transfer radical polymerization (DE-ATRP). Subsequently, processed into coatings by employing "grafting to" method....
ABSTRACT The structures and properties of PtAg n ( = 1–16) clusters have been studied by density functional theory (DFT). Tpssh/def2‐TZVP method is chosen in this work. Calculations reveal that the are planar when 1–3, while they present three‐dimensional 4–16. coordination number Pt atom range 1–11. atoms prefer to locate centers structures. electronic compared with available experimental theoretical data. stability analysis manifests odd‐even properties. study catalytic on perform similar...
A robustness-enhancing technique without additional computational cost in antenna optimization design is presented. The robustness implemented by minimizing the variances of gains, axial ratios, and VSWRs over required frequency band. It demonstrated that new has two obvious advantages. One advantage it can ensure extra overhead. other possible to broaden bandwidth antenna. We apply this a microstrip at 2.4 GHz. experimental results show that, adopting technique, evolved more robust than...
To enhance the robustness and stability of antenna design, a novel methodology is presented for modelling design problem as constrained optimisation (COP). Then framework introduced solving COP. The converts COP into an equivalent dynamic multi‐objective (DCMOP). A evolutionary algorithm applied to address transformed DCMOP, which means well can be solved. it three classes antennas: wire antenna, patch array. Obtained results these kinds suggest that proposed methods satisfy requirements.
Objective To evaluate the performance of 2D and 3D radiomics features with different machine learning approaches to classify SPLs based on magnetic resonance(MR) T2 weighted imaging (T2WI). Material Methods A total 132 patients pathologically confirmed were examined randomly divided into training (n = 92) test datasets 40). 1692 1231 per patient extracted. Both clinical data evaluated. 1260 classification models, comprising 3 normalization methods, 2 dimension reduction algorithms, feature...
A compact ultra-wideband microstrip-fed planar monopole antenna with dual band-notch characteristic is presented. Dual notched frequency bands are achieved by embedding an M-slot in the radiating patch and a W-slot ground beneath feeding line.

Abstract This paper is motivated by some recent work of Fukuda, Ishiwata, Iwasaki, and Nakamura ( Inverse Problems 2009; 25 :015007). We first design an algorithm for computing the eigenvalues a specially structured matrix from discrete Bogoyavlensky Lattice 2 (dBL2) system. A Lax representation dBL2 system given in form. By considering asymptotic behavior variables, characteristic polynomials are then factorized. new complex introduced. Copyright © 2010 John Wiley & Sons, Ltd.
