In this work, we report clean, surface protected and high quality topological insulator (TI) thin film Hall bar device of millimeter size long, without using any resist and lithography techniques. The pronounced effect of weak anti-localization (WAL) behavior has been observed in the magneto-transport measurements at low temperatures over the range T = 4–10 K and in the low field regions and as we go from 10 K onwards to higher temperatures the WAL cusp disappears, also we find that the high field magenetoresistance (MR) is linear in field. The MR behavior with respect to magnetic field (B) seems to be symmetric. We also report thickness dependent weak-anti localization (WAL) behavior in topological insulator Bi2Te3 thin film Hall bar device. Our systematic magneto-transport measurements for varying thickness reveal WAL signals obtain in thicker films, where as a sudden diminishment of the surface transport below the critical thickness of ∼4 nm has been observed by suppression of WAL behavior. The pronounced behavior of this effect is also found to be dependent on the temperatures, where the WAL cusps are observed at low temperatures in the low-field regions. © 2017 Elsevier Ltd

Measures of phylogenetic diversity are basic tools in many studies of systematic biology. Faith's PD (sum of branch lengths of a phylogenetic tree connecting all focal species) is the most widely used phylogenetic measure. Like species richness, Faith's PD based on sampling data is highly dependent on sample size and sample completeness. The sample-size-and sample-coverage-based integration of rarefaction and extrapolation of Faith's PD was recently developed to make fair comparison across multiple assemblages. However, species abundances are not considered in Faith's PD. Based on the framework of Hill numbers, Faith's PDwas generalized to a class of phylogenetic diversity measures that incorporates species abundances. In this article, we develop both theoretical formulae and analytic estimators for seamless rarefaction and extrapolation for this class of abundance-sensitive phylogenetic measures, which includes simple transformations of phylogenetic entropy and of quadratic entropy. Thiswork generalizes theprevious rarefaction/extrapolation model of Faith's PD to incorporate species abundance, and also extends the previous rarefaction/extrapolation model of Hill numbers to include phylogenetic differences among species. Thus a unified approach to assessing and comparing species/taxonomic diversity and phylogenetic diversity can be established. A bootstrap method is suggested for constructing confidence intervals around the phylogenetic diversity, facilitating the comparison of multiple assemblages. Our formulation and estimators can be extended to incidence data collected from multiple sampling units. We also illustrate the formulae and estimators using bacterial sequence data from the human distal esophagus and phyllostomid bat data from three habitats. © The Author(s) 2016.

Eshelby’s tensor of a general ellipsoidal inclusion in transversely isotropic materials is obtained by integrating the associated Green’s function over the surface of the ellipsoid. Unlike those derived via Fourier integral transform, the present mathematical expressions of the tensor involve some definite integrals that are related to those appearing in other branches of physics. Theoretical aspects concerning the real-valued integrals known in the past are generalized by introducing complex numbers to fit for the present context. Some divergent integrals encountered in the present study are discussed in detail. It is concluded that only the finite parts or the principal values of the integrals are needed for the evaluation of the Eshelby tensor. © 2017 Springer-Verlag Wien

How the artistic oval squid uses its changing skin pattern to communicate with lovers and competitors, and the researchers who have deciphered their language for the first time William Shakespeare wrote with a quill, Helen Keller liked her typewriter, and the oval squid prefers to use its body, when it comes to expressing love. But unlike these famous authors, the romanticisms of Sepioteuthis lessoniana were unknown. Until now. Recent research out of the National Tsing Hua University (Taiwan), and published in Frontiers in Ecology and Evolution, has finally deciphered the previously unknown symbols and shapes the oval squid decorates itself in, and how they are used. The animals make use of naturally occurring chromatic components, which are stored within their bodies. They use these to paint their skin with lines, spots and stripes, of varying shades and complexities, to signal their desirability to future lovers and warn off potential foes. Researchers, led by Prof Chiao, took to the East China Sea, near the city of Taipei, to study the oval squid in the wild. Underwater they built an attractive home, made of bamboo branches and leaves, to provide the female oval squid a safe place to nest, lay their eggs, and provide shelter to hatchlings. Over the course of three months scuba divers recorded the movements and displays of the gathering squid, looking for repeating patterns of tone change between mating partners. Amazingly they also observed the underwater show included elegant and specific movements that varied depending on the gender and social status. For instance, should two males get into a fight over a possible partner, then they will swim around each other, vying for the higher position. The conclusion of this "dance" is when the winner literally ends up on top of the loser. He cements this victory with a strong visual display, broadcasting his success to all, including his future mate. The loser is not completely defeated however as he can still have a chance to fertilize some of the female's eggs, all be it outside of her egg laying period. In a rapid movement which the researchers termed "male-upturned mating", the squid will approach above her, flip himself upside down, place his sperm and scoot away, passing on his genes to the next generation. Female oval squid are polyandrous, meaning that they will, during their egg laying period, take multiple males to be their mate. Like the fighting males, they too will use expressive patterns to determine possible partners. A dark pattern on her body indicates a rejection of the pursing male's advances. In total, the researchers found five common behavior patterns with their own intricate movements and tone signals, and which are also dependent on an individual squid's standing in the group. This intricate language of patterns, movements and associated behaviors have been compiled into an "ethogram" (a dictionary of a species' communication methods) which will assist in future behavioral studies, not just in these expressive cephalopods, but in other species too. In time, we may come to understand the exact meanings in the symbols the romantic oval squid adorns on its body. But until then, we will have to make do with the sonnets of Shakespeare to make our partner swoon.

Tsinghua University stood out from 20 teams from around the world after a fierce one-week competition, becoming grand champion and winning the prize. As the world's largest supercomputing competition, ASC17 received applications from 230 universities around the world, 20 of which got through to the final round held this week at the National Supercomputing Center in Wuxi after the qualifying rounds. During the final round, the university student teams were required to independently design a supercomputing system under the precondition of a limited 3000W power consumption. They also had to operate and optimize standard international benchmark tests and a variety of cutting-edge scientific and engineering applications including AI-based transport prediction, genetic assembly, and material science. Moreover, they were required to complete high-resolution maritime simulation on the world's fastest supercomputer, "Sunway TaihuLight". The grand champion, team Tsinghua University, completed deep parallel optimization of the high-resolution maritime data simulation mode MASNUM on TaihuLight, expanding the original program up to 10,000 cores and speeding up the program by 392 times. This helped the Tsinghua University team win the e Prize award. MASNUM was nominated in 2016 for the Gordon Bell Prize, the top international prize in the supercomputing applications field. The runner-up, Beihang University, gave an outstanding performance in the popular AI field. After constructing a supercomputing system which received massive training based on past big data of transportation provided by Baidu, their self-developed excellent deep neural network model yielded the most accurate prediction of road conditions during the morning peak. The first-time finalist, Weifang University team, constructed a highly optimized advanced heterogeneous supercomputing system with Inspur's supercomputing server, and ran the international HPL benchmark test, setting a new world record of 31.7 TFLOPS for float-point computing speed. The team turned out to be the biggest surprise of the event and won the award for best computing performance. Moreover, Ural Federal University, National Tsing Hua University, Northwestern Polytechnical University and Shanghai Jiao Tong University won the application innovation award. The popular choice award was shared by Saint-Petersburg State University and Zhengzhou University.

"This event inspired students to gain advanced scientific knowledge. TaihuLight is an amazing platform for this event. Just imagine the interconnected computation of everyone's computer in a gymnasium housing 100,000 persons, and TaihuLight's capacity is 100 times of such a gym. This is something none of the teams will ever be able to experience again." According to Wang Endong, initiator of the ASC competition, academician of the Chinese Academy of Engineering, and the chief scientist of Inspur Group, the rapid development of AI at the moment is significantly changing human society. At the core of such development are computing, data and algorithms. With this trend, supercomputers will become an important infrastructure for intelligent society in the future, and their speed of development and standards will be closely related to social development, improvement in livelihood, and progress of civilization. ASC competition is always committed to cultivating future-oriented, inter-disciplinary supercomputing talents to extend the benefits to the greater population.

The WiMAX Forum has defined a two-tiered mobility management to minimize handover delay and packet loss. However, it leads to another problem: When to perform ASN GW relocation? The standards only define the ASN GW relocation procedures without specifying when the ASN GW relocation should be performed. It is left for vendors and operators to develop their own proprietary solutions. In this paper, we propose an algorithm, which incorporates traditional Admission Control (AC) and Wiener Process (WP)-based prediction algorithms to determine when to carry out ASN GW relocation. We further develop an analytical model to analyze the proposed algorithm. Simulations are also conducted to evaluate the performance of the proposed algorithm. The results show that the proposed algorithm can improve the performance significantly in terms of blocking probability, dropping probability, average serving rate, and average signaling overhead. © 2006 IEEE.

Orchidaceae, renowned for its spectacular flowers and other reproductive and ecological adaptations, is one of the most diverse plant families. Here we present the genome sequence of the tropical epiphytic orchid Phalaenopsis equestris, a frequently used parent species for orchid breeding. P. equestris is the first plant with crassulacean acid metabolism (CAM) for which the genome has been sequenced. Our assembled genome contains 29,431 predicted protein-coding genes. We find that contigs likely to be underassembled, owing to heterozygosity, are enriched for genes that might be involved in self-incompatibility pathways. We find evidence for an orchid-specific paleopolyploidy event that preceded the radiation of most orchid clades, and our results suggest that gene duplication might have contributed to the evolution of CAM photosynthesis in P. equestris. Finally, we find expanded and diversified families of MADS-box C/D-class, B-class AP3 and AGL6-class genes, which might contribute to the highly specialized morphology of orchid flowers.

In situ investigation of the temperature induced phase transformation, structural and chemical evolution of nanocrystals is important for understanding the structure and stability of nanomaterials. Transmission electron microscopy (TEM), one of the most powerful tools for characterizing nanostructured materials, is essential for the development of nanotechnology. In situ TEM is a technique that allows a direct observation of dynamic properties in nanoscale. Recent development of ultra-high vacuum TEM (UHV-TEM) further enables the investigation on atomic-scale materials systems in a clean environment. The appropriate utilization of the UHV-TEM will be beneficial in studying the fundamental mechanisms of dynamic reactions, formation of transient phase, solid-state amorphization, epitaxial growth, growth kinetics and evolution of defects. In this paper, we present the most recent progress in observing dynamic processes in nanoscale by in situ UHV-TEM. © 2010 Elsevier B.V. All rights reserved.

This article reports a comparative study of five measures that quantify the degree of research collaboration, including the collaborative index, the degree of collaboration, the collaborative coefficient, the revised collaborative coefficient, and degree centrality. The empirical results showed that these measures all capture the notion of research collaboration, which is consistent with prior studies. Moreover, the results showed that degree centrality, the revised collaborative coefficient, and the degree of collaboration had the highest coefficient estimates on research productivity, the average JIF, and the average number of citations, respectively. Overall, this article suggests that the degree of collaboration and the revised collaborative coefficient are superior measures that can be applied to bibliometric studies for future researchers. © 2011 Elsevier Ltd.

EURECNET is a network that brings together national REC associations, networks or comparable initiatives but also other bodies relevant in the field of research involving human participants like National Ethics Councils and the European Commissions ethical review system. Such a network forms the infrastructural basis to promote awareness of specific working practices of RECs across Europe, to enhance the shared knowledge base of European RECs, to support coherent reviews and opinions and to meet new challenges and emerging ethical issues. The central objective of EURECNET as a Coordinating Action is to foster the already existing network of European REC networks (in short EUREC). In particular, the contribution of EURECNET aims at five different levels: - fostering a sustainable infrastructure for European RECs (including a statute and a secretariat) to promote exchange and cooperation and to allow for international cooperation; - gathering information on RECs in Europe to build a basis for mutual exchange - collecting and evaluating training materials for REC members to enhance the quality of review; - conducting capacity building to facilitate the development of national REC networks (as future partners of EUREC); - identifying emerging ethical issues to develop common solutions for challenges posed by new technologies and scientific methodologies.

The present disclosure coats an amorphous silicon (Si) layer on a doped Si substrate of a solar cell. Or, a silicon dioxide (SiO_(2)) layer is grown on the doped Si substrate and beneath the amorphous Si layer. A heterojunction interface and a homojunction interface are formed in the solar cell in a one-time diffusion. Thus, a heterojunction solar cell can be easily fabricated and utilities compatible to those used in modern production can still be used for reducing cost.

We propose an integrated sampling, rarefaction, and extrapolation methodology to compare species richness of a set of communities based on samples of equal completeness (as measured by sample coverage) instead of equal size. Traditional rarefaction or extrapolation to equal-sized samples can misrepresent the relationships between the richnesses of the communities being compared because a sample of a given size may be sufficient to fully characterize the lower diversity community, but insufficient to characterize the richer community. Thus, the traditional method systematically biases the degree of differences between community richnesses. We derived a new analytic method for seamless coverage-based rarefaction and extrapolation. We show that this method yields less biased comparisons of richness between communities, and manages this with less total sampling effort. When this approach is integrated with an adaptive coverage-based stopping rule during sampling, samples may be compared directly without rarefaction, so no extra data is taken and none is thrown away. Even if this stopping rule is not used during data collection, coveragebased rarefaction throws away less data than traditional size-based rarefaction, and more efficiently finds the correct ranking of communities according to their true richnesses. Several hypothetical and real examples demonstrate these advantages. © 2012 by the Ecological Society of America.

Nanoantennas for visible and infrared radiation can strongly enhance the interaction of light with nanoscale matter by their ability to efficiently link propagating and spatially localized optical fields. This ability unlocks an enormous potential for applications ranging from nanoscale optical microscopy and spectroscopy over solar energy conversion, integrated optical nanocircuitry, opto-electronics and density-of-states engineering to ultra-sensing as well as enhancement of optical nonlinearities. Here we review the current understanding of metallic optical antennas based on the background of both well-developed radiowave antenna engineering and plasmonics. In particular, we discuss the role of plasmonic resonances on the performance of nanoantennas and address the influence of geometrical parameters imposed by nanofabrication. Finally, we give a brief account of the current status of the field and the major established and emerging lines of investigation in this vivid area of research. © 2012 IOP Publishing Ltd.

This paper introduces an H-representation method to express an n 2×1 vector X as X =H ∼X. Based on the introduced H-representation approach, several topics are extensively discussed, including the generalized Lyapunov equations (GLEs) arising from stochastic control, stochastic observability, generalized D-stability and D-stabilization, weak stability, and stabilization. A necessary and sufficient condition for the existence and uniqueness of the symmetric and skew-symmetric solutions of GLEs is presented, respectively. Moreover, the solution structure of GLEs is also clarified. Through the H-representation method, several necessary and sufficient conditions are also obtained for stochastic observability, generalized D-stability and D-stabilization, weak stability, and stabilization. © 1963-2012 IEEE.

A new soft computing method called the parameter-free simplified swarm optimization (SSO)-based artificial neural network (ANN), or improved SSO for short, is proposed to adjust the weights in ANNs. The method is a modification of the SSO, and seeks to overcome some of the drawbacks of SSO. In the experiments, the iSSO is compared with five other famous soft computing methods, including the backpropagation algorithm, the genetic algorithm, the particle swarm optimization (PSO) algorithm, cooperative random learning PSO, and the SSO, and its performance is tested on five famous time-series benchmark data to adjust the weights of two ANN models (multilayer perceptron and single multiplicative neuron model). The experimental results demonstrate that iSSO is robust and more efficient than the other five algorithms. © 2012 IEEE.

This work uses a novel rule-based classifier design method, constructed by using improved simplified swarm optimization (SSO), to mine a thyroid gland dataset from UCI databases. An elite concept is added to the proposed method to improve solution quality, close interval encoding (CIE) is added to efficiently represent the rule structure, and the orthogonal array test (OAT) is added to powerfully prune rules to avoid over-fitting the training dataset. To evaluate the classification performance of the proposed improved SSO, computer simulations are performed on well-known thyroid gland data. Computational results compare favorably with those obtained using existing algorithms such as conventional classifiers, including Bayes classifier, k-NN, k-Means, and 2D-SOM, and soft computing based methods such as the simple SSO, immune-estimation of distribution algorithms (IEDA), and genetic algorithm (GA). © 2012 Elsevier Inc.

The main goal of this review is to provide systematic elucidation of the correlation between structural characters and the photophysical properties of a series of heavy transition metal complexes. Depending on types of metal ions, chromophoric and ancillary ligands, several intriguing cases encountered in our recent studies will be exemplified as prototypes to shed light on their excited-state relaxation pathways. Particular attention is paid to: (i) the intersystem crossing and/or radiative decay rates versus contribution of the metal dπ orbital, (ii) crucial factors that facilitate the radiationless deactivation, such as the metal-centred dd transition, resulting in weakness of the metal-ligand bond, and other transitions weakening the specific bonds and flexible structural framework that induces the low-frequency vibrational deactivation, (iii) intra-ligand versus inter-ligand charge transfer affecting the photophysical properties; that is, an issue of current interest regarding whether to treat the whole transition metal complex as a single entity or as several distinctive chromophores separated by the core metal ion. We then formulate a discussion from the standpoint of fundamental photophysical theory. The results, together with modern computational approaches for supplementary support, allow us to make adequate comparison with respect to classic organic fluorescence counterparts. Many similarities can be identified between organic fluorophores and late transition metal based phosphors; nevertheless, certain distinctions can also be extracted. We then conclude this review by providing guidelines on how to harvest the emission via suppressing the weighting of radiationless deactivation routes. However, for transition metal complexes, quantitative assessment of radiationless deactivation and hence the accurate prediction of emission efficiency is still a long term goal to be attained. © 2010 Elsevier B.V.

The end-of-life (EOL) disassembly sequencing problem (DSP) has become increasingly important in the process of handling EOL products. This paper proposes a solution procedure for the "EOL DSP"; the procedure is based on a novel soft-computing algorithm that utilizes modified "simplified swarm optimization", and the procedure combines the precedence preservative operator, feasible solution generator, self-adaptive parameter control, and repetitive pairwise exchange procedures. By taking into consideration the non-deterministic polynomial time (NP)-complete nature of the problem, the proposed algorithm efficiently seeks the optimal disassembly sequence with a novel approach; this approach involves reducing the initial solution space and using a combination of soft-computing algorithms for achieving higher computational efficiency and solution quality. The results presented in this paper show that the proposed algorithm outperforms the existing algorithms in terms of solution quality achieved in a limited computation time. © 2006 IEEE.
