Further technological development of perovskite solar cells (PSCs) will require improvements in power conversion efficiency and stability, while maintaining low material costs and simple fabrication. In this Research Article, we describe top-illuminated ITO-free, stable PSCs featuring microcavity structures, wherein metal layers on both sides on the active layers exerted light interference effects in the active layer, potentially increasing the light path length inside the active layer. The optical constants (refractive index and extinction coefficient) of each layer in the PSC devices were measured, while the optical field intensity distribution was simulated using the transfer matrix method. The photocurrent densities of perovskite layers of various thicknesses were also simulated; these results mimic our experimental values exceptionally well. To modify the cavity electrode surface, we deposited a few nanometers of ultrathin MoO3 (2, 4, and 6 nm) in between the Ag and poly(3,4-ethylenedioxythiophene):polystyrenesulfonate (PEDOT:PSS) layers provide hydrophobicity to the Ag surface and elevate the work function of Ag to match that of the hole transport layer. We achieved a power conversion efficiency (PCE) of 13.54% without hysteresis in the device containing a 4 nm-thick layer of MoO3. In addition, we fabricated these devices on various cavity electrodes (Al, Ag, Au, Cu); those prepared using Cu and Au anodes displayed improved device stability of up to 72 days. Furthermore, we prepared flexible PSCs having a PCE of 12.81% after incorporating the microcavity structures onto poly(ethylene terephthalate) as the substrate. These flexible solar cells displayed excellent stability against bending deformation, maintaining greater than 94% stability after 1000 bending cycles and greater than 85% after 2500 bending cycles performed with a bending radius of 5 mm.

In this paper, we aim at using genetic algorithms for gene selection and propose silhouette statistics as a discriminant function to classify breast cancers on microarray data for pattern discovery. In order to see the causality among these genes, we use the Bayesian method to construct a probability network for the pattern discovered. Consequently, we found a set of genes that is effective to discriminate breast cancer subtypes and present their probability dependencies to construct a diagnostic system.

Research Article - Abstract
Jen-Chieh Shiao, Chien-Yu Chen, Jie Zhang, and Yoshiyuki Iizuka (2016) Salangid icefish (Salangidae) are commercially important species and are widely distributed in lakes, rivers, estuaries, and coastal area of Asia. This study examined their habitat use and migratory patterns by analyzing otolith microstructure and Sr/ Ca ratios. Neosalanx tangkahkeii and Protosalanx chinesis collected in the isolated freshwater Taihu Lake in China showed consistently low otolith Sr/Ca ratios (< 5.0 × 10-3, mean + 2 SD), which were used to represent the freshwater residence. Another batch of P. chinesis collected from the Yangtze River estuary of China also showed low otolith Sr/Ca ratios (< 5.5 × 10-3, mean + 2 SD) throughout the life history, suggesting that these fish only use freshwater environments. A group of N. tangkahkeii collected in the Pearl River estuary of China showed otolith Sr/Ca ratios between 10.0 × 10-3 and 30.0 × 10-3, indicating habitat shifts between brackish and marine environments. Salanx ariakenesis collected in the Yangtze River estuary showed variable and higher otolith Sr/Ca ratios between 1.6 × 10-3 and 36.5 × 10-3, exhibiting the diverse migratory patterns between the river and the sea with the habitat shifts occurring at the juvenile, young, and adult stages. Neosalanx anderssoni collected in the Bohai Sea, China only used marine habitats based on their consistently high otolith Sr/Ca ratios with the mean values of each fish varying between 20.7 × 10-3 and 24.6 × 10-3. The habitat use by the icefish may differ within and among species. Different migratory patterns can coexist in the same species e.g., S. ariakenesis. The euryhaline icefish, even those living in the estuary or coastal water, do not necessarily migrate between the sea and rivers, suggesting their high plasticity of habitat use and facultative anadromous behaviors

If the twist $Poincar\acute{e}$ transformation is imposed on the noncommutative spacetime, then $Lorentz$ invariance cannot be applied on QFT. To data, noncommutative theory is one of the best candidates to modify $Lorentz$ transformation. In this paper, we argue parity violation under the process of $e^{+}e^{-}\to\gamma \gamma$ and make a detailed analysis of the difference behavior of each helicity state on noncommutative spacetime. The effect arises from the production of spin and magnetic fields. We check the energy momentum conservation for all used couplings and discover that if the electric field changes particle energy spectrum, there is no symmetry violation as the field produces a longitudinal state on the finial triple boson couplings., Comment: 8 pages, 7 figures

In this paper, we consider a time dependent module field on spacetime extension without modifying commutative relation on noncommutative quantum plane. The significant idea is that $Lorentz$ symmetry is conserved in module and unmodule coordinate. We focus on the redefinition of spacetime structure without considering noncommutative bosonic gas in deforming the product between fields. Which the null vector is a vector on orthogonal $D$ dimensional $Hilbert$ spacetime. In $Riemann$ geometry, the equation of motion is deformed from an induced rotation. Particle field survives on the state composed by two theoretical assumed $null$ vectors, one is commutative, another is anticommutative. In the point of view, neutrino and photon mass are produced by its shift, the rotated effect generates a horizon in redefining particle field., 10 pages

We report a new type of phase-change materials based upon the compound of In-Ga-O. It is found to exhibit two-order of magnitude resistivity change between the high-resistive amorphous phase and the low-resistive cubic phase at a phase-change temperature ~250degC. When the In-Ga-O is incorporated into a nonvolatile phase change memory (PCM) device with a double-heater (DH) structure, it exhibits an on/off resistance ratio of 1000 and cycling over 300 times which are superior to those observed on a single-heater (SH) PCM device. These results, together with a low bias point of 70 muA at 6.5 volt and 1.5 mA at 3.5 volt, respectively, for set/ reset operation of the DH-PCM device to the crystalline/amorphous state, suggest that In-Ga-O is a promising material candidate for low power application of PCM devices.

We discuss the process of Higgs boson production in $\gamma\gamma$ collider on noncommutative spacetime and compare the results with large extra dimension in KK graviton channel. Summing all KK mode on IR brane, the affections are in the same order by comparing noncommutatve model prediction. This process is completely forbidden in standard model on unitarity condition and bosonic distribution. In noncommutative theory, the effect is induced by the coordinates noncommutable relation, $[x^{\mu}, x^{\nu}]$ = $i\theta^{\mu\nu}$. Due to the constant background strength tensor does not contain any conserved quantum number, hence, this effort is indicated into particle power spectrum. Particle mass spectrum is corrected by radiational and anisotropic surroundings. The process of $\gamma\gamma\to H^{0}H^{0}$ restricts the unitarity condition in noncommutative field theory. Under power law conservation condition, the neutral Higgs mass below gauge boson resonance will produce a accelerated phenomena as the central energy is higher than $Z_{0}$ gauge boson creation scale. The effects generated from the vast light Higgs particles descend the power rate energy distribution as far as the ambient is under a balance. The fractional rate on polarized polars are very small embedded into the unpolarized surroundings depend on background electric field couplings., Comment: 15 pages, 19 figures

This article proposes a novel density estimation based algorithm for carrying out supervised machine learning. The proposed algorithm features O(n) time complexity for generating a classifier, where n is the number of sampling instances in the training dataset. This feature is highly desirable in contemporary applications that involve large and still growing databases. In comparison with the kernel density estimation based approaches, the mathe-matical fundamental behind the proposed algorithm is not based on the assump-tion that the number of training instances approaches infinite. As a result, a classifier generated with the proposed algorithm may deliver higher prediction accuracy than the kernel density estimation based classifier in some cases., Inclusion of a new "Remarks" section

In recent years, kernel density estimation has been exploited by computer scientists to model machine learning problems. The kernel density estimation based approaches are of interest due to the low time complexity of either O(n) or O(n*log(n)) for constructing a classifier, where n is the number of sampling instances. Concerning design of kernel density estimators, one essential issue is how fast the pointwise mean square error (MSE) and/or the integrated mean square error (IMSE) diminish as the number of sampling instances increases. In this article, it is shown that with the proposed kernel function it is feasible to make the pointwise MSE of the density estimator converge at O(n^-2/3) regardless of the dimension of the vector space, provided that the probability density function at the point of interest meets certain conditions., The new version includes an additional theorem, Theorem 3
