Leaf Glyph - Visualizing Multi-dimensional Data with Environmental Cues

In exploratory data analysis, important analysis tasks include the assessment of similarity of data points, labeling of outliers, identifying and relating groups in data, and more generally, the detection of patterns. Specifically, for large data sets, such tasks may be effectively addressed by glyph-based visualizations. Appropriately defined glyph designs and layouts may represent collections of data to address these aforementioned tasks. Important problems in glyph visualization include the design of compact glyph representations, and a similarityor structure-preserving 2D layout. Projection-based techniques are commonly used to generate layouts, but often suffer from over-plotting in 2D display space, which may hinder comparing and relating tasks. We introduce a novel glyph design for visualizing multi-dimensional data based on an environmental metaphor. Motivated by the humans ability to visually discriminate natural shapes like trees in a forest, single flowers in a flower-bed, or leaves at shrubs, we design a leaf-shaped data glyph, where data controls main leaf properties including leaf morphology, leaf venation, and leaf boundary shape. We also define a custom visual aggregation scheme to scale the glyph for large numbers of data records. We show by example that our design is effectively interpretable to solve multivariate data analysis tasks, and provides effective data mapping. The design also provides an aesthetically pleasing appearance, which may help spark interest in data visualization by larger audiences, making it applicable e.g., in mass media.
Vertex Packing Decoding

In this work, we present a new framework for developing decoding algorithms for linear block codes. We define a new graphical model, called configuration graph and show that maximum likelihood (ML) sequence decoding can be performed by finding a maximum vertex packing on a configuration graph. We present examples of low-cost decoding algorithms developed using this graphical model and show that remarkable performance improvements can be achieved especially by combining these algorithms with belief propagation (BP) decoding for Low Density Parity Check (LDPC) codes.
CULTURAL PROFILE OF RUSSIAN LEADERSHIP

The study presented in this paper aims to formulate a composite profile of Russian organizational leadership based on a review and analysis of research conducted in the last 15 years by Western and Russian scholars. Russian leadership will be approached from the perspectives of cross-cultural organizational research and implicit leadership theory. First, perceptions of effective Russian leadership will be explored in a number of studies, including the GLOBE project. Other studies will also be used for evidence of current organizational leadership practice in Russia. A comparative analysis within and between both sets of studies is then expected to reveal areas of commonality, general trends, and principles with regard to how leadership is perceived and practiced in Russia. The projected results of this study include better cross-cultural understanding, comparison, and assessment of Russian leadership by foreign and local organizational members.
Dual-Mode Dual-Band Bandpass Filter Using a Single Slotted Circular Patch Resonator

A single slotted circular patch resonator is proposed in this letter to design a novel dual-mode dual-band bandpass filter. Four identical arc-oriented slots are first symmetrically etched into the circular patch resonator to move the TM01-like mode to a lower frequency. Together with the TM21-like mode, these two modes make up the second passband of the proposed filter. A pair of radial-oriented slots is then etched into the edge of the circular patch to split a pair of TM11-like degenerate modes, which forms the first dual-mode passband. Two high-impedance transmission lines are connected to the proposed resonator at a 90° angle to properly excite the four resonant modes described above. Finally, a filter with input/output cross coupling is designed, fabricated and tested to demonstrate the dual-mode dual-band filtering performance, which exhibits a sharp out-of-band rejection skirt and good rejection between the dual passbands.
Numerical study of dynamic Smagorinsky models in large‐eddy simulation of the atmospheric boundary layer: Validation in stable and unstable conditions

Large‐eddy simulation (LES) of atmospheric boundary layer (ABL) flow is performed over a homogeneous surface with different heat flux forcings. The goal is to test the performance of dynamic subgrid‐scale models in a numerical framework and to compare the results with those obtained in a recent field experimental study (HATS (Kleissl et al., 2004)). In the dynamic model the Smagorinsky coefficient cs is obtained from test filtering and analysis of the resolved large scales during the simulation. In the scale‐invariant dynamic model the coefficient is independent of filter scale, and the scale‐dependent model does not require this assumption. Both approaches provide realistic results of mean vertical profiles in an unstable boundary layer. The advantages of the scale‐dependent model become evident in the simulation of a stable boundary layer and in the velocity and temperature spectra of both stable and unstable cases. To compare numerical results with HATS data, a simulation of the evolution of the ABL during a diurnal cycle is performed. The numerical prediction of cs from the scale‐invariant model is too small, whereas the coefficients obtained from the scale‐dependent version of the model are consistent with results from HATS. LES of the ABL using the scale‐dependent dynamic model give reliable results for mean profiles and spectra at stable, neutral, and unstable atmospheric stabilities. However, simulations under strongly stable conditions (horizontal filter size divided by Obukhov length >3.8) display instabilities due to basic flaws in the eddy viscosity closure, no matter how accurately the coefficient is determined.
Low Thermal Sensitivity Grating Devices Based on Ex-45$^{\circ}$ Tilting Structure Capable of Forward-Propagating Cladding Modes Coupling

The authors describe a detailed investigation on tilted fiber Bragg grating (TFBG) structures with tilted angles exceeding 45deg. In contrast to the backward mode coupling mechanism of Bragg gratings with normal and small tilting structures, the ex-45deg TFBGs facilitate the light coupling to the forward-propagating cladding modes. The authors have also theoretically and experimentally examined the mode coupling transition of TFBGs with small, medium, and large tilt angles. In particular, experiments are conducted to investigate the spectra and far-field distribution, as well as temperature, strain, and refractive-index sensitivities of ex-45deg devices. It has been revealed that these ex-45deg gratings exhibit ultralow thermal sensitivity. As in-fiber devices, they may be superior to conventional Bragg and long-period gratings when the low thermal cross sensitivity is required
Comparing various voice recognition techniques

In this paper we describe and compare some speaker recognition techniques. A mel-cepstral short-time analysis for speech signals is presented first. It is used in the voice feature extraction stage. Then speech-dependent and speech-independent speaker recognition approaches are proposed by us in this paper. Minimum mean-distance classification methods are used by the supervised classifier of the voice identification system. Threshold-based procedures are provided for the speaker verification part of the system.
$H_\infty$ Control and Estimation of Retarded State-Multiplicative Stochastic Systems

Linear, state-delayed, continuous-time systems with stochastic uncertainties in their state-space model are considered. The problems of both Hinfin state-feedback control and filtering are solved, for the stationary case, via an input-output approach by which the system is replaced by a nonretarded system with deterministic norm-bounded uncertainties. In both problems, a cost function is defined that is the expected value of the standard Hinfin performance index with respect to the uncertain parameters. Three examples are given that demonstrate the applicability of the theory.
Establishing a Theoretical Background for a Museum-centric Entertainment System

The use of gaming to provide additional value to cultural experiences, like museums visits, is not novel. The increased possibilities to access the game market opened by online platforms make the communicative and emotional characteristics of digital games an opportunity for promotion. In this paper, we discuss the theoretical foundations of an approach aimed at producing digital games meant to be part of a continuing emotional experience. We draw from psychological and museological research to motivate our view on the relationships between game designers and museum experts. By concentrating on archaeological and art museums, we advocate for the need of a methodological approach to the design of games for museums aimed at promoting the value of cultural experience as it is, thus countering the plethora of technological instalments that often risk averting the attention from the collection.
Phylogenomics and historical biogeography of the monocot order Liliales: out of Australia and through Antarctica

We present the first phylogenomic analysis of relationships among all ten families of Liliales, based on 75 plastid genes from 35 species in 29 genera, and 97 additional plastomes stratified across angiosperm lineages. We used a supermatrix approach to extend our analysis to 58 of 64 genera of Liliales, and calibrated the resulting phylogeny against 17 fossil dates to produce a new timeline for monocot evolution. Liliales diverged from other monocots 124 Mya and began splitting into separate families 113 Mya. Our data support an Australian origin for Liliales, with close relationships between three pairs of lineages (Corsiaceae/Campynemataceae, Philesiaceae/Ripogonaceae, tribes Alstroemerieae/Luzuriageae) in South America and Australia or New Zealand reflecting teleconnections of these areas via Antarctica. Long‐distance dispersal (LDD) across the Pacific and Tasman Sea led to re‐invasion of New Zealand by two lineages (Luzuriaga, Ripogonum); LDD allowed Campynemanthe to colonize New Caledonia after its submergence until 37 Mya. LDD permitted Colchicaceae to invade East Asia and Africa from Australia, and re‐invade Africa from Australia. Periodic desert greening permitted Gloriosa and Iphigenia to colonize Southeast Asia overland from Africa, and Androcymbium–Colchicum to invade the Mediterranean from South Africa. Melanthiaceae and Liliaceae crossed the Bering land‐bridge several times from the Miocene to the Pleistocene.
Optimizing Web Service Composition for Data-intensive Applications

The accessing, transferring and processing of data need to occur parallel in order to tackle the problem brought on by the increasing volume of data on the Internet. In this paper, we put forward the parallel schema for data-intensive Web services and the Benefit Ratio of Composite Services (BROCS) to balance the throughput and cost. Furthermore, we present the method to determine the degree of parallelism (DOP) based on the BROCS model to optimize the quality of the composite services. The experiment demonstrates how DOP affects the benefit ratio of the composite service. Meanwhile, the results based on the 250,000 Microblog items published by Sina show that our proposed parallel schema for Web services could effectively improve the efficiency of the composite Web service.
New substrate-integrated to coplanar waveguide transition

A novel design for a transition from substrate-integrated waveguide (SIW) to regular coplanar waveguide (CPW) is presented. In comparison with previously published transitions, which employ conductor-backed CPWs and via holes, the new design achieves better return-loss performance. Dispersion curves highlight the related modes and the available bandwidths. The new design is optimized in an HFSS environment and is presented as a single transition and as a back-to-back version with more than 30 dB and 26 dB return loss, respectively, over a bandwidth of 19.5 GHz to 27 GHz. All design parameters are specified. A SIW-to-conductor-backed CPW and via holes is presented for comparison, showing return-loss values of only 21 dB and 14.5 dB. All presented performances include dielectric and metallic losses and are verified by comparisons between HFSS and CST Microwave Studio.
Time-Dependent Reliability Models of Systems with Common Cause Failure

Reliability models of systems with common cause failure are developed through system-level load-strength interference analysis. Based on the statistic meaning of random load action and the failure mechanism of systems under repeated random load, the effect of multiple action of random load on reliability is studied. The probability cumulative distribution function and the probability density function of equivalent load are derived with the order statistic, and the reliability models of systems under repeated random load are derived. Further, the loading process is described by the Poisson stochastic process, the time-dependent reliability models of a series system, a parallel system and a k-out-of-n system are developed, and the relationship between reliability and time and that between the failure rate and time are discussed respectively. Finally, a simulation experiment is carried out to verify the reliability model proposed with the Monte Carlo method.
Response: DonorNet and the Potential Effects on Organ Utilization

We appreciate the comments provided by Kayler et al. (1) in response to our recent publication ‘DonorNet and the Potential Effects on Organ Utilization’ (2). As we emphasized in the article, the many influences on organ utilization, which may change over time, make it challenging to isolate the impact of DonorNet on each individual patient. Therefore, we agree that caution must be exercised in drawing firm conclusions from the data. Nevertheless, we will address the authors’ questions with respect to our interpretation of the data.
The Surface Hydro-Oxidation of LaNiO3-xThin Films

LaNiO3 is one of the few conductive oxides with a crystal structure suitable for integration in epitaxial heterostructures with perovskites of enormous technological potential such as colossal magnetoresistance materials, high-temperature superconductors, and ferroelectrics. It is known that the considerable surface segregation of elements may take place in LaNiO3−x samples [1]. Another factor to be considered is the tendency of rare earth oxides to absorb water vapor and carbon dioxide from air, so that any ex situ exposure of these films to air will result in an uncontrolled reaction and surface stoichiometry [2].

Response to Drs. Mauriño and Bai

TO THE EDITOR: We read with interest the recent article by Dickey and Hughes (1). In this study, the authors questioned the sensitivity of endoscopic markers to detect villous atrophy in celiac disease patients. The authors made reference to our previous study on the topic, which was based on fiberoptic upper endoscopy and where we evaluated all those markers associated with the presence of villous atrophy (2). As they mentioned, we proved a 94% of sensitivity for any marker for patients with severe atrophy. Interestingly, that study showed that fold loss was the most prevalent finding at the fiberendoscopic examination. However, there is another, more recently published article by our group (3) that was not quoted or referred to by Dickey and Hughes. In that study, we reported original data on the usefulness of videoendoscopy, on the one hand, and the role of vital dye staining in the detection of celiac disease. A secondary aim of the study was to assess interobserver agreement for all markers. Data provided by our study confirmed 94% sensitivity for any marker. However, contrasting with our former study, scalloped folds and mosaic pattern were the most prevalent markers (86% and 89%, respectively). The most realistic explanation for discrepancies in prevalence of signs between our first and last articles could be the consequence of the different magnitudes of magnification of the fiberendoscopy and videoendoscopy methods. A more pertinent point of our study that was coincident with those findings of Dickey and Hughes is the fact that we also detected false-negative videoendoscopies for patients otherwise diagnosed with celiac disease. Such an event occurred in five of 16 patients with partial villous atrophy (mainly treated cases). Dickey and Hughes suggested that endoscopies not performed because of a high suspicion of celiac disease can underestimate recognition of the disorder and that dye staining can improve sensitivity. However, our last study did not agree with this suggestion. By contrast, although the method of vital dying produced a better delineation of scalloped folds and mosaic, it only provided results identical to those obtained by simple inspection alone. In conclusion, despite some disappointing sensitivity, we still believe that endoscopic markers for villous atrophy are very useful for diagnosis of celiac disease and that training of endoscopists in recognition of such markers is perhaps the most effective incidental action to improve suspicion of celiac disease.
Internal Fixation of Sacroiliac Joint via Posterior Approach in Management of Posterior Pelvic Injuries

Object: Sacroiliac dislocation frequently poses a complex problem for the surgical management and stabilization because of the anatomical and biomechanical factors of this transition zone between the spine and pelvis. The authors had used a modification of the Galveston technique, originally described by Allen and Ferguson in the treatment of scoliosis, to achieve rigid spinal-pelvic fixation in patient’s sacroiliac dislocation with vertical and rotational shear. Methods: Twelve patients who had required spinal-pelvic fixation secondary to sacroiliac dislocation and instability fixation was achieved by intraoperative placement of S1 pedicle screws and contoured titanium rods bilaterally into the
Production/maintenance cooperative scheduling using multi-agents and fuzzy logic

Within companies, production is directly concerned with the manufacturing schedule, but other services like sales, maintenance, purchasing or workforce management should also have an influence on this schedule. These services often have together a hierarchical relationship, i.e. the leading function (most of the time sales or production) generates constraints defining the framework within which the other functions have to satisfy their own objectives. We show how the multiagent paradigm, often used in scheduling for its ability to distribute decision-making, can also provide a framework for making several functions cooperate in the schedule performance. Production and maintenance have been chosen as an example: having common resources (the machines), their activities are actually often conflicting. We show how to use a fuzzy logic in order to model the temporal degrees of freedom of the two functions, and show that this approach may allow one to obtain a schedule that provides a better compromise between the satisfaction of the respective objectives of the two functions.

A Stochastic Adaptive Robust Optimization Approach for the Offering Strategy of a Virtual Power Plant

This paper proposes a novel approach for the offering strategy of a virtual power plant that participates in the day-ahead and the real-time energy markets. The virtual power plant comprises a conventional power plant, a wind-power unit, a storage facility, and flexible demands, which participate in the day-ahead and the real-time markets as a single entity in order to optimize their energy resources. We model the uncertainty in the wind-power production and in the market prices using confidence bounds and scenarios, respectively, which allows us to formul-ate the strategic offering problem as a stochastic adaptive robust optimization model. Results of a case study are provided to show the applicability of the proposed approach.
A novel twelve level inverter topology for adaptive input sources

A new twelve level three-phase inverter topology based on a computing model that can pre-calculate switching angles is proposed. The main advantage of this topology is that the number of input DC voltage sources, power electronic switches, pre-calculated switching angles, and the total harmonics distortion in the output voltage are all reduced. This means that the topology can be connected to the network with small size inductance. Applications that could use this new topology include the dynamic hybrid battery/inverter and photovoltaic/inverter systems to improve overall system operation and performance and at the same time improve output voltage and power generation quality. The proposed topology has been modeled and validated using Matlab software.
A 9.2b 47fJ/conversion-step asynchronous SAR ADC with input range prediction DAC switching

This paper presents a 10b 500KS/s asynchronous successive approximation register analog-to-digital converter (SAR ADC) with input range prediction DAC switching technique for low power applications. The proposed input range prediction DAC switching technique narrows down the traditional try-and-error range of the input signal to prevent unnecessary DAC switching, and the average switching energy is 90% more efficient than the conventional approach. A prototype is fabricated in 0.18um CMOS technology. With a single supply of 1V, it achieves an ENOB, SNDR and FoM of 9.24b, 57.3dB, and 47fJ/Conversion-step at 500KS/s sampling rate, respectively.
Cardiac PET image segmentation by a deformable model with a force field driven speed term

Automatic, unsupervised image segmentation is playing an important role in medical imaging, but remains a challenging task in positron emission tomography (PET) due to unpredictable object shapes and inconsistent image quality resulting from noise and sampling artifacts. In this paper, we present an application of the class of deformable models, the so-called level sets method, where the speed term in the evolution equation of motion has been modified to allow the boundary curves of a detected structure to move forward and backward. This was performed by introducing a gravitational-like force field that is proportional to the gradient and inversely proportional to the distance in order to control the direction and the speed of the contours evolution. The model was applied to the automatic segmentation of the PET images of a mouse myocardium as measured by the Sherbrooke LabPET scanner.
