Libraries of basic blocks enable the description of complex systems, including high-order sigma-delta modulators. The symbolic results produce various types of output depending on the kind of post-processing required. Examples of use of the tool are provided.
Amphitheater-headed canyons formed by megaflooding at Malad Gorge, Idaho

Significance The shapes of bedrock canyons offer clues to the history of surface water on Earth and Mars. Using field examples in Idaho, we found that canyons with amphitheater-shaped heads were likely carved rapidly by outburst flooding about 46,000 y ago and that canyons with more pointed heads evolved progressively by river erosion over tens of thousands of years. Our study suggests that the many amphitheater-headed canyons in fractured basalt on Mars, long inferred to be carved by groundwater seepage, may owe their origins instead to megafloods. Many bedrock canyons on Earth and Mars were eroded by upstream propagating headwalls, and a prominent goal in geomorphology and planetary science is to determine formation processes from canyon morphology. A diagnostic link between process and form remains highly controversial, however, and field investigations that isolate controls on canyon morphology are needed. Here we investigate the origin of Malad Gorge, Idaho, a canyon system cut into basalt with three remarkably distinct heads: two with amphitheater headwalls and the third housing the active Wood River and ending in a 7% grade knickzone. Scoured rims of the headwalls, relict plunge pools, sediment-transport constraints, and cosmogenic (3He) exposure ages indicate formation of the amphitheater-headed canyons by large-scale flooding ∼46 ka, coeval with formation of Box Canyon 18 km to the south as well as the eruption of McKinney Butte Basalt, suggesting widespread canyon formation following lava-flow diversion of the paleo-Wood River. Exposure ages within the knickzone-headed canyon indicate progressive upstream younging of strath terraces and a knickzone propagation rate of 2.5 cm/y over at least the past 33 ka. Results point to a potential diagnostic link between vertical amphitheater headwalls in basalt and rapid erosion during megaflooding due to the onset of block toppling, rather than previous interpretations of seepage erosion, with implications for quantifying the early hydrosphere of Mars.
Physical and physiological demands of elite team handball players

The aim of this study was to analyse physical and physiological demands of elite team handball players. Nineteen men from a professional handball team played a simulated 30-min match in an outdoor sport facility. Instantaneous speed during the games was assessed using GPS devices and the number of body-impacts above 5-g was measured by accelerometry. Individual heart rate was also measured by using heart rate monitors. Handball players covered 94.0±7.7 m/min during the simulated match with a mean of 82.5±4.7 % of maximal heart rate. The average speed of the wingmen was significantly higher than pivots, centres and backcourt players (102.5±1.8 vs. 94.4±4.6, 92.6±1.0 and 86.1±6.0 m/min, respectively; P<0.05). Running pace at sprint speed (e.g.,<18 km/h) was on average 2.4±2.3 m/min but it was significantly higher in wingmen than in the remaining playing positions (4.5±2.4 vs 0.5±0.1, 2.4±1.7 and 1.3±1.0 m/min, respectively; P<0.05). The overall number of body-impacts was 13.6±7.7 per min of game with pivots being the players that presented the highest values (17.2±5.7 impacts/min; P<0.05). Physical demands of elite handball are primarily related to high-intensity actions, impacts and rapid recovery during the game. The training of elite handball players should be specific to the exercise actions performed during the game.
Secure Index for Resource-Constraint Mobile Devices in Cloud Computing

With the rapid development of network technology and cloud computing, more and more organizations and users outsource their data into the cloud server. In order to protect data privacy, the sensitive data have to be encrypted, which increases the heavy computational overhead and brings great challenges to resource-constraint devices. In this paper, we propose secure index based on counting Bloom filter (CBF) for ranked multiple keywords search. In the proposed scheme, several algorithms are designed to maintain and lookup CBF, while a pruning algorithm is used to delete the repeated items for saving the space. Besides, the relevance scores are encrypted by the Paillier cryptosystem. It ensures that the same relevance scores are encrypted into different bits, which can resist the statistical analyses on the ciphertext of the relevance scores. Moreover, since the Paillier cryptosystem supports the homomorphic addition of ciphertext without the knowledge of the private key, the major computing work in ranking could be moved from user side to the cloud server side. Therefore, the proposed scheme has huge potentials in resource-constraint mobile devices such as 5G mobile terminals. Security analyses prove that the proposed scheme can prevent the information leakage. Experiment results guarantee that computation overhead of the proposed scheme in user side is low.
An evaluation of self-training styles for domain adaptation on the task of splice site prediction

We consider the problem of adding a large unlabeled sample from the target domain to boost the performance of a domain adaptation algorithm when only a small set of labeled examples are available from the target domain. In particular, we consider the problem setting motivated by the task of splice site prediction. For this task, annotating a genome using machine learning requires a lot of labeled data, whereas for non-model organisms, there is only some labeled data and lots of unlabeled data. With domain adaptation one can leverage the large amount of data from a related model organism, along with the labeled and unlabeled data from the organism of interest to train a classifier for the latter. Our goal is to analyze the three ways of incorporating the unlabeled data - with soft labels only (i.e., Expectation-Maximization), with hard labels only (i.e., self-training), or with both soft and hard labels - for the splice site prediction in particular, and more broadly for a general iterative domain adaptation setting. We provide empirical results on splice site prediction indicating that using soft labels only can lead to better classifier compared to the other two ways.
Autoreactive T cell responses in insulin-dependent (Type 1) diabetes mellitus. Report of the first international workshop for standardization of T cell assays.

Type 1 diabetes is thought to result from a T cell-mediated destruction of the pancreatic beta-cells. Multiple and sometimes conflicting studies have identified a variety of aberrations in the cellular immune response to autoantigens in persons with the disease. Potential explanations for these discrepancies include incomparable techniques or culture conditions, diversity in the populations of patients or controls tested, and differences in autoantigen preparations. A T cell workshop was organized by the Immunology of Diabetes Society with the aim of appreciating and identifying problems associated with autoreactive T cell assays in type 1 diabetes. As a first phase, a series of candidate autoantigens were analysed by reference laboratories for quality. Subsequently, these preparations, as well as control stimuli, were distributed in a blind fashion to 26 laboratories worldwide, including all experienced centres, for analysis of T cell proliferation assays in 10 recent onset type 1 diabetes and 10 non-diabetic controls. For this analysis, participants used their own assays and references. The islet autoantigen quality control analyses performed prior to the distribution indicate that the quality of recombinant autoantigen preparations requires improvement. For example, several T cell clones specific for glutamic acid decarboxylase (GAD65) were unable to cross-react with GAD65 expressed in baculovirus, yeast or bacteria. Moreover, autoantigens expressed in E. coli interfered with autoantigen-specific proliferation of both T cell clones and peripheral blood mononuclear cells. Nonetheless, responses could be measured to all autoantigen preparations evaluated in the workshop. During the blind phase of the study, all centres were able to reproducibly measure T cell responses to two identical samples of tetanus toxoid, but there was significant interlaboratory variation in sensitivity and extent of the proliferative response measured. Third, the results using candidate autoantigens indicated that although a few laboratories could distinguish type 1 diabetes patients from non-diabetic controls in proliferative responses to individual islet autoantigens, in general, no differences in T cell proliferation between the two groups could be identified. This first T cell workshop on T cell autoreactivity in type 1 diabetes confirms that this was a difficult area for interlaboratory investigations, but provided insight towards future efforts focused on standardizing autoreactive T cell measurements. Some previously reported conflicting results can in part be explained by the observed interlaboratory variability. The inability to discriminate normal controls from new onset type 1 diabetes patients suggests that measuring proliferative responses in PBMC represents an incomplete picture of the immune response, perhaps complicated by difficulties in identifying suitable antigens and assays for standardized use.
Memory Interfaces: Past, Present, and Future

Over the last few decades, the bandwidth of dynamic random-access memory (DRAM) has increased significantly through innovative architectures and circuit-level techniques to overcome the well-known "memory wall" problem. We can understand the past challenges of DRAM input/output (I/O) by investigating the technologies utilized for DRAM I/O in the transition from single-data-rate (SDR) synchronous DRAM (SDRAM)to double-data-rate (DDR) SDRAM. Recently developed versions of low-power DDR four (LPDDR4) and synchronous graphics DDR five (GDDR5) employ new I/O features for further bandwidth increase. Looking beyond LPDDR4 and GDDR5, what should be done to make another jump in bandwidth increase for DRAM?
Dimensionality and the Development of Cognitive Assessments for Children in Sub-Saharan Africa

Over the past decade, researchers have shown increased interest in examining the cognitive development of children in non-Western countries, often in connection with evaluations of health and educational interventions. However, many studies have used Western-developed measures without proper consideration of contextual validity. Across domains—from language to cognition to non-cognitive skills—this results in varying degrees of bias that call into question the findings of these studies. In this article, we focus in particular on the problem of differences in dimensionality perception between children in sub-Saharan Africa and those in Western countries. Although most Western children are exposed to extensive two-dimensional materials during early childhood, such as picture books and photographs, most rural African children are not. We therefore argue that assessments using two-dimensional stimuli, such as line drawings or patterns, may be inappropriate for capturing cognitive development in settings where such formats are unfamiliar to young children. We also discuss a modified assessment of non-verbal reasoning designed to be contextually appropriate for children in rural Africa—the Object-based Pattern Reasoning Assessment (OPRA). Created during a national study of pre-school child development in Zambia, this new assessment uses local materials such as beans and stones, requires little training to administer, and avoids potential instrument bias related to two-dimensionality among young children living in developing countries.
Physical and Electrical Property of TiO2 Nanotube Arrays for Supercapacitors

TiO2 nanotube arrays (TiO2 NTAs) were prepared by anodization method. The as-prepared TiO2 NTAs were annealed at 450 °C for 3 h transforming amorphous TiO2 to anatase TiO2. The inner diameter and tube length of synthesized TiO2 NTAs are approximately 100 nm and 1.0 mm, respectively. Electric double-layer capacitor (EDLC) was fabricated using TiO2 NTAs as electrodes with 6 M KOH electrolyte. The internal resistance of the EDLC is relatively low (3.8 – 6.5 Ω) depending on the operating temperature. This work confirmed experimentally the use of TiO2 NTAs as EDLC electrodes.
On the design of hybrid limited feedback for massive MIMO systems

The increase of antennas can greatly improve the performance of MIMO systems, in the meanwhile, the precise channel state information is difficult to obtain since the channel matrix of massive MIMO is much more complex than the traditional one. In this paper, we propose a limited feedback strategy named hybrid limited feedback with selective eigenvalue information (HLFSEI), which jointly considers the conventional quantized feedback and codebook based feedback. In HLFSEI, because of the large amount of the elements of channel matrix, the quantized information of only selective eigenvalue elements is fed back from the receiver to the transmitter with feedback-link capacity constraint. We study the optimal feedback bit allocation of both feedback methods to maximize the throughput by theoretic deduction. Finally, we evaluate the performance of the proposed limited feedback scheme by simulation and show its performance gain compared to conventional feedback strategies.
Loktanella spp. Gb03 as an algicidal bacterium, isolated from the culture of Dinoflagellate Gambierdiscus belizeanus

Aim: Bacteria associated with harmful algal blooms can play a crucial role in regulating algal blooms in the environment. This study aimed at isolating and identifying algicidal bacteria in Dinoflagellate culture and to determine the optimum growth requirement of the algicidal bacteria, Loktanella sp. Gb-03. Materials and Methods: The Dinoflagellate culture used in this study was supplied by Professor Gires Usup's Laboratory, School of Environmental and Natural Resources Sciences, Faculty of Science and Technology, University Kebangsaan Malaysia, Malaysia. The culture was used for the isolation of Loktanella sp. , using biochemical tests, API 20 ONE kits. The fatty acid content of the isolates and the algicidal activity were further evaluated, and the phenotype was determined through the phylogenetic tree. Results: Gram-negative, non-motile, non-spore-forming, short rod-shaped, aerobic bacteria (Gb01, Gb02, Gb03, Gb04, Gb05, and Gb06) were isolated from the Dinoflagellate culture. The colonies were pink in color, convex with a smooth surface and entire edge. The optimum growth temperature for the Loktanella sp. Gb03 isolate was determined to be 30°C, in 1% of NaCl and pH7. Phylogenetic analysis based on 16S rRNA gene sequences showed that the bacterium belonged to the genus Loktanella of the class Alphaproteobacteria and formed a tight cluster with the type strain of Loktanella pyoseonensis (97.0% sequence similarity). Conclusion: On the basis of phenotypic, phylogenetic data and genetic distinctiveness, strain Gb-03, were placed in the genus Loktanella as the type strain of species. Moreover, it has algicidal activity against seven toxic Dinoflagellate. The algicidal property of the isolated Loktanella is vital, especially where biological control is needed to mitigate algal bloom or targeted Dinoflagellates.
Real-Time Molecular Visualization Supporting Diffuse Interreflections and Ambient Occlusion

Today molecular simulations produce complex data sets capturing the interactions of molecules in detail. Due to the complexity of this time-varying data, advanced visualization techniques are required to support its visual analysis. Current molecular visualization techniques utilize ambient occlusion as a global illumination approximation to improve spatial comprehension. Besides these shadow-like effects, interreflections are also known to improve the spatial comprehension of complex geometric structures. Unfortunately, the inherent computational complexity of interreflections would forbid interactive exploration, which is mandatory in many scenarios dealing with static and time-varying data. In this paper, we introduce a novel analytic approach for capturing interreflections of molecular structures in real-time. By exploiting the knowledge of the underlying space filling representations, we are able to reduce the required parameters and can thus apply symbolic regression to obtain an analytic expression for interreflections. We show how to obtain the data required for the symbolic regression analysis, and how to exploit our analytic solution to enhance interactive molecular visualizations.

Virtual XML: A toolbox and use cases for the XML world view

Although the Extensible Markup Language (XML) has gained in popularity and has resulted in the creation of powerful software for authoring, transforming, and querying XML-based business data, much information remains in non-XML form. In this paper we introduce an approach to virtualize data resources and thus enable applications to access both XML and non-XML sources. We describe the architectural components that enable virtual XML-a toolbox that includes a cursor model, an XML-view mechanism such as the view created with the Data Format Description Language (DFDL), and XML processing languages. We illustrate the applicability of virtual XML through a number of use cases in various environments. We discuss the products that we expect from vendors and the open-source community and the way enterprises can plan to take advantage of virtual XML developments. Finally, we outline future research directions that include a vision of virtual XML that covers large-scale structures such as entire file systems, databases, or even the World Wide Web.
Block Co-Polymers for Nanolithography: Rapid Microwave Annealing for Pattern Formation on Substrates

The integration of block copolymer (BCP) self-assembled nanopattern formation as an alternative lithographic tool for nanoelectronic device fabrication faces a number of challenges such as defect densities, feature size, pattern transfer, etc. Key barriers are the nanopattern process times and pattern formation on current substrate stack layers such as hard masks (e.g., silicon nitride, Si3N4). We report a rapid microwave assisted solvothermal (in toluene environments) self-assembly and directed self-assembly of a polystyrene-block-polydimethylsiloxane (PS-b-PDMS) BCP thin films on planar and topographically patterned Si3N4 substrates. Hexagonally arranged, cylindrical structures were obtained and good pattern ordering was achieved. Factors affecting BCP self-assembly, notably anneal time and temperature, were studied and seen to have significant effects. Graphoepitaxy within the topographical structures provided long range, translational alignment of the patterns. The effect of surface topography feature size and spacing was investigated. The solvothermal microwave based technique used to provide periodic order in the BCP patterns showed significant promise and ordering was achieved in much shorter periods than more conventional thermal and solvent annealing methods. The implications of the work in terms of manufacturing technologies are discussed.
Retinopathy in chronic hepatitis C patients during interferon treatment with ribavirin

AIM To assess the ocular effect of interferon alfa 2b prescribed with ribavirin in patients undergoing therapy for chronic hepatitis C. METHODS 19 patients with chronic hepatitis C who satisfied the follow up criteria were assessed for ocular complications using slit lamp biomicroscopy and indirect ophthalmoscopy before, during, and after the treatment at regular intervals. RESULTS 8/19 patients, while on treatment, developed an asymptomatic retinopathy. Among these 3/8 were relapsers and 5/9 were non-responders to interferon monotherapy. All retinal changes faded, often while the patients continued the therapy. There was no significant association in occurrence of retinopathy with haematological and/or biochemical changes. CONCLUSION Retinopathy was more common in interferon monotherapy non-responders than relapsers when treated with interferon alfa 2b with the addition of ribavirin. The changes were transient, disappearing while the patients were still being treated.
