Study of Factors Affecting Micro-barriers that Hinders the Development of Private Enterprises: Mediating Role of Intention to Use of Renewable Energy

Private enterprises in Vietnam as well as in other countries play an important role in the economy, but they have encountered several barriers in their development at both micro and macro levels. Inquires of these barriers is meaningful in making policy recommendations to remove barriers to private enterprise development in countries where the State/Government is considered a major factor. This study focuses on evaluating factors affecting the micro-barrier system that hinder the development of private enterprises in Vietnam to answer two research questions: which factors influence micro-barriers that hinder the development of private enterprises in Vietnam and what is the degree of influence of those factors along with the mediating impact of intention to use of renewable energy? The study applies quantitative research methods to measure the impact of factors on the micro-barriers system that hinder private enterprise development based on the survey sample of 392 private enterprises in Vietnam, which are mainly small and medium-sized private enterprises (most affected by micro barriers). Research findings indicate that state management policies; legal and tax systems, expanding scientific research and technological innovation activities are the main factors affecting the micro barriers that hinder the development of private enterprises in Vietnam. Intention to use of renewable energy significantly mediates between competitiveness in production and business, support for scientific research and technological innovation activities, expanding cooperation and international integration, state management policy, law and tax and barriers restricting enterprise development. These results could become experiences for other countries like Vietnam.
Insights into the Physics of Flapping Flight: Extending Axioms on Force Generation, Flow Features and Body Deformation in Insect Flight

Here, the backward flight of a dragonfly was investigated. In this flight, the insect took off from a platform and flew backward and upward for about 3 wingbeats (WB) traveling a distance of over 3 body lengths with an advance ratio of 0.41. The dragonfly initiated flight with a body pitch angle of 87o and continued to pitch up to about 95o as it flew. The stroke planes of the wings were tilted backward towards the body, thus, reducing the stroke plane angle when compared to forward flight by 15o. Due to the global reorientation of the stroke plane owing to the vertical body posture, the aerodynamic roles of the downstroke and upstroke were switched, with the downstroke generating the propulsive force and upstroke generating the lift force. Unlike forward and hovering flight, a stronger leading edge vortex (LEV) was present during the upstroke when compared to downstroke, resulting in generation of larger aerodynamic forces in the upstroke necessary for weight support.
Indium-Ill Activity Concentration in Tissue Samples After Intravenous Injection of Indium-111-DTPA-D-Phe-l-Octreotide

Methods: lndium-111 activityconcentrationsin human tumor and normal tissue samples were determined at 24, 48 and 120 hr after i.v. injection of111ln-DTPA-D-Phe-1 -octreotide. Fourteen patients were included in the study. Seven patients had medul lary thyroid carcinoma, four had midgut carcinoid tumors, two had endocrine pancreatic tumors and one had chronic pancre atitis. Results: For midgut carcinoids, the tumor-to-blood ratio was 51:220, for medullary thyroid carcinoma 4:39, and for two endocrine pancreatic tumors 6 and 1500. Tumor-to-muscle ra tios varied between 1 and 1200 and tumor-to-fat between 2 and 1500 depending on tumor type. Conclusion: The sometimes extremely high tumor-to-normal tissue ratios present the possi bility for use of radiolabeled octreotide for radiation therapy of somatostatJn receptor positive tumors.
Electrostatic gating of hybrid halide perovskite ﬁ eld-effect transistors: balanced ambipolar transport at room-temperature

The hybrid halide perovskites combine the low-cost processing characteristics of organic materials with the performance factors of inorganic compounds. Recently the power conversion ef ﬁ ciencies of perovskite photovoltaic solar cells have reached a respective value of ∼ 20%. The charge transport properties were indirectly approximated in these compounds because of lack of available ﬁ eld-effect transistors (FETs). Here we report the fabrication and room-temperature operation of FETs based on the hybrid perovskites. We obtained balanced electron and hole transport with mobilities of ∼ 1 cm 2 /Vs. We also found that the yield, as well as the operational and environmental stability of the fabricated transistors is limited.
The Disturbance Rejection Control Method Based on the External Load Force Feed-forward Compensation of the Hydraulic Drive Unit

The high performance bionic quadruped robot is driven by the hydraulic drive unit (HDU), and to compensate the negative effects of the external load force on the HDU performance availably, the external load force feedforward compensation control method is researched in this paper. Therefore, the deficiency of the position control performance with integral separation PI control under external load force is given. And the load pressure observer is designed to compute the load pressure of the HDU. Moreover, the external load force feedforward compensation controller is designed and applied. And control effects are obtained by experiment and simulation analysis under the typical external load force and robot’s trot gait work condition. The research results indicate that the response speed and the control accuracy of the HDU position control system are improved availably with this compensation control method.
Study of the Electromagnetic Interference Generated by Wireless Power Transfer Systems

This paper presents a study related with measuring of radio frequency emissions. The purpose is to determine the level of interference generated by wireless power transfer equipment in a specific frequency range, and to compare those levels to the existing standards. The technology of wireless power transfer, especially for electric vehicles batteries charging, is rapidly developing in the recent years. An increasing use of this technology in industrial and consumer electronic products has raised concerns about the possible unfavorable health-effects onto the human being. Another concern is raised from the high intensity fields produced by wireless power transfer systems which will generate highly undesired influence on other electrical and electronic equipment. As a protection against the potential health effects, the governments imposed limits on the occupational and general public exposure to the radio frequencies. These limitations are set out in national and international safety guidelines, standards and regulations. The measurement and evaluation of the human exposure to electromagnetic fields are essential to guarantee occupational and general public safety.
Supergenes on steroids

At the birth of supergenes, the genomic landscape is dramatically re-organized leading to pronounced differences in phenotypes and increased intrasexual diversity. Two of the best-studied supergenes in vertebrates are arguably the inversion polymorphisms on chromosomes 2 and 11 in the white-throated sparrow (Zonotrichia albicollis) and the ruff (Calidris pugnax), respectively. In both species, regions of suppressed recombination determine plumage coloration and social behavioural phenotypes. Despite the apparent lack of gene overlap between these two supergenes, in both cases the alternative phenotypes seem to be driven largely by alterations in steroid hormone pathways. Here, we explore the interplay between genomic architecture and steroid-related genes. Due to the highly pleiotropic effects of steroid-related genes and their universal involvement in social behaviour and transcriptomic regulation, processes favouring their linkage are likely to have substantial effects on the evolution of behavioural phenotypes, individual fitness, and life-history strategies. We propose that inversion-related differentiation and regulatory changes in steroid-related genes lie at the core of phenotypic differentiation in both of these interesting species.

Genome-wide association mapping within a local Arabidopsis thaliana population more fully reveals the genetic architecture for defensive metabolite diversity

A paradoxical finding from genome-wide association studies (GWAS) in plants is that variation in metabolite profiles typically maps to a small number of loci, despite the complexity of underlying biosynthetic pathways. This discrepancy may partially arise from limitations presented by geographically diverse mapping panels. Properties of metabolic pathways that impede GWAS by diluting the additive effect of a causal variant, such as allelic and genetic heterogeneity and epistasis, would be expected to increase in severity with the geographical range of the mapping panel. We hypothesized that a population from a single locality would reveal an expanded set of associated loci. We tested this in a French Arabidopsis thaliana population (less than 1 km transect) by profiling and conducting GWAS for glucosinolates, a suite of defensive metabolites that have been studied in depth through functional and genetic mapping approaches. For two distinct classes of glucosinolates, we discovered more associations at biosynthetic loci than the previous GWAS with continental-scale mapping panels. Candidate genes underlying novel associations were supported by concordance between their observed effects in the TOU-A population and previous functional genetic and biochemical characterization. Local populations complement geographically diverse mapping panels to reveal a more complete genetic architecture for metabolic traits.

Tactile Texture Display Combining Vibrotactile and Electrostatic-friction Stimuli: Substantial Effects on Realism and Moderate Effects on Behavioral Responses

There is increasing demand for tactile feedback functions for touch panels. We investigated whether virtual roughness texture quality can be improved through simultaneous use of vibrotactile and electrostatic-friction stimuli. This conjunctive use is expected to improve the perceptual quality of texture stimuli, because vibrotactile and electrostatic-friction stimuli have complementary characteristics. Our previous studies confirmed that these conjunct stimuli yield enhanced realism for simple grating roughness. In this study, we conducted experiments using simple and complex sinusoidal surface profiles consisting of one or two spatial wave components. Three different evaluation criteria were employed. The first criterion concerned the subjective realism, i.e., similarity with actual roughness textures, of virtual roughness textures. Participants compared the following three stimulus conditions: vibrotactile stimuli only, electrostatic-friction stimuli only, and their conjunct stimuli. The conjunct stimuli yielded the greatest realism. The second criterion concerned roughness texture identification under each of the three stimulus conditions for five different roughness textures. The highest identification accuracy rate was achieved under the conjunct stimulus condition; however, the performance difference was marginal. The third criterion concerned the discrimination threshold of the grating-scale spatial wavelength. There were no marked differences among the results for the three conditions. The findings of this study will improve virtual texture quality for touch-panel-type surface tactile displays.
Adaptive Clock Management of HLS-generated Circuits on FPGAs

In this article, we present Syncopation, a performance-boosting fine-grained timing analysis and adaptive clock management technique for High-Level Synthesis-generated circuits implemented on Field-Programmable Gate Arrays. The key idea is to use the HLS scheduling information along with the placement and routing results to determine the worst-case timing path for individual clock cycles. By adjusting the clock period on a cycle-by-cycle basis, we can increase performance of an HLS-generated circuit. Our experiments show that Syncopation improves performance by 3.2% (geomean) across all benchmarks (up to 47%). In addition, by employing targeted synthesis techniques along with Syncopation, we can achieve 10.3% performance improvement (geomean) across all benchmarks (up to 50%). Syncopation instrumentation is implemented entirely in soft logic without requiring alterations to the HLS-synthesis toolchain or changes to the FPGA, and has been validated on real hardware.
N-terminal Mutants of Chloroplast Cytochrome f EFFECT ON REDOX REACTIONS AND GROWTH IN CHLAMYDOMONAS REINHARDTII

The N-terminal tyrosine of cytochrome f , which pro- vides the sixth ligand to the heme group, has been changed by site-directed mutagenesis in Chlamydomo- nas reinhardtii to evaluate the role of this amino acid in assembly and function. The second and third residues, proline and valine, respectively, have also been mutated. Y1P is the only strain that did not grow photoau- totrophically. The other strains show cytochrome b 6 f complex/photosystem I reaction center chlorophyll, photosystem I unit size and chlorophyll a (cid:49) b /cell ratios comparable with wild-type cells. Rates of cytochrome f photooxidation in all strains were similar ( t 1 ⁄ 2 (cid:62) 300 (cid:109) s), whereas the rate of re-reduction sensitive to stig- matellin (at E h (cid:53) 0 mV, (where E h is the ambient redox potential) for wild-type, Y1W, Y1F, Y1S, P2V, and V3P had a t 1 ⁄ 2 of 3, 4, 5, 9, 40, and 2 ms, respectively. Rates of oxygen evolution by whole cells of P2V, Y1F, and Y1S were 67, 80, and 80% of wild-type rates, respectively. At low light intensity, all competent strains had the same growth rate whereas at saturating intensities, only P2V showed a significant inhibition. These results are con-sidered in relation to structure-function relationships in the cytochrome f molecule. 160, and 0 mV. The results from both approaches are almost identical as regards the extent and kinetics of the cytochrome for a train of eight flashes 60 ms apart. This demon- strates that the wavelength pair 554–545 nm satisfactorily deconvo-lutes cytochrome f from other overlapping signals at a variety of redox change levels of cytochrome f and of the other components of the electron transfer chain.
Chaos identification through the auto-correlation function indicator (ACFI)

Abstract Close encounters or resonances overlaps can create chaotic motion in small bodies in the Solar System. Approaches that measure the separation rate of trajectories that start infinitesimally near, or changes in the frequency power spectrum of time series, among others, can discover chaotic motion. In this paper, we introduce the ACF index (ACFI), which is based on the auto-correlation function of time series. Auto-correlation coefficients measure the correlation of a time-series with a lagged duplicate of itself. By counting the number of auto-correlation coefficients that are larger than 5% after a certain amount of time has passed, we can assess how the time series auto-correlates with each other. This allows for the detection of chaotic time-series characterized by low ACFI values.
The winds of change? A comparative study of community energy developments in Scotland and Wales

Renewable energy is a growing sector as nation states aim to curtail their carbon emissions and establish a more sustainable strategy to generate energy. However, there are disputes that large scale renewable energy developments replicate corporate and centralist traditions of energy generation and fail to contribute towards community sustainability and local economies. Community Energy projects – renewable energy projects that are part or fully owned by a geographically distinct community – are seen as a means of generating energy in a way that is more sympathetic, equitable and sustainable. Unforeseen social and economic benefits accrue from community energy projects such as community cohesiveness, higher financial returns, autonomy and resilience, a sense of local pride through ownership and behavioural change through an increased understanding of sustainability issues and energy consumption. Apart from contributing to the overall production of energy from renewable sources, community energy projects also seem to have the added benefit of attaining more support within their locality. This is of crucial value when bearing in mind opposition to the development of some renewable energy projects. There are also disparities in how such projects are diffused and supported, particularly within the UK. Focusing on the sub-state nations of Scotland and Wales, this thesis looks in depth at the experiences of developing community energy in peripheral and rural Welsh and Scottish Gaelic speaking areas of both devolved countries. Through a series of in-depth, semi-structured interviews with community energy actors in four case sites across north-west Scotland and north-west Wales alongside a Delphi method questionnaire amongst specialists working in the field at sub state level, the research draws a picture of the current state of the community energy sector in both nations. The research shows that support structures in Scotland have contributed to a sense of confidence amongst communities to develop local energy generating projects. This is reflected in the number of successful Scottish community energy case sites currently operational. This confidence, at time of researching, was lacking in Wales. A clear case was made that more focus and support was needed for the niche sector to grow in Wales. It was also evident that communities viewed cultural sustainability as intrinsic to the development of their community energy projects – an added benefit that has not been accredited with the sector in any previous research.The thesis furthermore contributes to an understanding of the optimal conditions for the development of community energy projects in Wales and Scotland, how the relationship between incumbent actors and geographically peripheral communities currently operates and the unforeseen cultural benefits of such projects.
Broadband Design of Reflect-Array Antenna Using Genetic-Swarm-Optimization Method*

The printed reflect-array (RA) is widely used in satellite communication system as a good substitute for the parabolic reflector due to its low profile, easy fabrication, low cost and light weight, but its bandwidth and aperture efficiency are less than the latter. In order to keep high gain within a wide bandwidth, at first the broadband elements with multilayer structures are recommended, and also the phase compensation should be insensitive to frequency. Though the delay-lines can completely compensate the phase difference caused by different lengths of ray paths, they are inconvenient in structure. On the other side, the single-layer sized patches can flexibly control the phase of reflection coefficient; however, it becomes sensitive to the frequency. So a broadband reflect-array should be designed for multi-frequency optimization, rather than for single frequency only. Various optimization methods had been developed for antenna design. One kind of those evolutionary methods outperforms others due to their simple implementation, and no constraints on solution domain. Among them, the Genetic Algorithm (GA) can find global solution with slow convergence speed, while the Particle Swarm Optimization (PSO) converges fast with being easily trapped in local maxima. Thus, the combination of GA and PSO can realize global optimization with fast convergence. As presented below, an optimization method called Genetic-Swarm-Optimization (GSO) [1] algorithm is employed to design the entire RA structure on a specified frequency range. In this paper, firstly the reflection phase vs. element sizes is analyzed; and also the phase- and amplitude-distribution of illuminated field at each element depending on the feed pattern and ray-path difference are calculated. Then the GSO algorithm with fast convergence is programmed and then run for the target of maximized gain with wider bandwidth as possible (> 20 %), and restriction of side-lobe-level (SLL< –15 dB), by means of adjusting the parameters as sizes and position of each element. The simulated result for optimized structure indicates that the maximal gain approaches 18.7 dBi, which is 1 dB higher than that of principial design without optimization; about 32.3 % bandwidth (8.3~11.5 GHz) for –1.6 dB gain-drop; and –14.6dB SLL at 10 GHz are performed.
Proposal of 0.5 mg of protein/100 g of processed food as threshold for voluntary declaration of food allergen traces in processed food—A first step in an initiative to better inform patients and avoid fatal allergic reactions: A GA²LEN position paper

Food anaphylaxis is commonly elicited by unintentional ingestion of foods containing the allergen above the tolerance threshold level of the individual. While labeling the 14 main allergens used as ingredients in food products is mandatory in the EU, there is no legal definition of declaring potential contaminants. Precautionary allergen labeling such as “may contain traces of” is often used. However, this is unsatisfactory for consumers as they get no information if the contamination is below their personal threshold. In discussions with the food industry and technologists, it was suggested to use a voluntary declaration indicating that all declared contaminants are below a threshold of 0.5 mg protein per 100 g of food. This concentration is known to be below the threshold of most patients, and it can be technically guaranteed in most food production. However, it was also important to assess that in case of accidental ingestion of contaminants below this threshold by highly allergic patients, no fatal anaphylactic reaction could occur. Therefore, we performed a systematic review to assess whether a fatal reaction to 5mg of protein or less has been reported, assuming that a maximum portion size of 1kg of a processed food exceeds any meal and thus gives a sufficient safety margin.
