An Investigation of the Determinants of SMEs’ Innovation in Hanoi

Innovation is considered an important premise to create competitiveness and to achieve long-term growth of the company in the ever-changing business environment. Enterprises are constantly improving their innovation and creativity to survive and develop. The issue of innovation is increasingly attracting the attention of researchers, business administrators and policy makers. Small and medium-sized enterprises (SMEs) are essential elements of the economy, and businesses have a responsibility to foster innovation and competition in many economies. To be competitive in such economies, SMEs must successfully support strategic management decisions. The problem can lie at the decision stage depending on the market conditions with many external and internal factors. Perspectives on creating a driving force to promote innovation and to develop the private sector quickly and sustainably, together help build and strengthen a socialist-oriented market economy. Constantly promoting business support, especially SMEs, is one of the key tasks of Hanoi city. This study proposes to investigate how the use of internal and external factors influences the innovation process of SMEs. Therefore, the aim of the study is to comprehensively present the factors affecting innovation. The research is conducted based on the use of theoretical background of enterprise innovation activities with 07 main factors including: (1) Technological capabilities; (2) Innovation culture; (3) Innovation strategy; (4) Management skills; (5) Innovation policy; (6) Collaboration with businesses on innovation; and (7) Access to financial support. On that basis, the author conducts a survey and analysis by quantitative method at SMEs in Hanoi about the current status of innovation activities to provide a practical view of the determinants of innovation for SMEs in Hanoi. The proposed analytical framework with specific groups of factors is suggested for businesses, researchers and state management agencies on enterprises to have further practical studies on this topic as well as consult and make appropriate policies.
General model for sag-tension calculation of composite conductors

A new computer model is presented for precise calculation of sag and tensions of composite conductors for overhead lines. All the effects known to increase the sag are accounted for: residual deformations, evolution of creep with time, compression in aluminum layer of ACSR conductors at high temperature, etc. This general model can also be applied for the simpler cases of one-material conductors and messengers supporting multiples or telecommunication cables.
A novel tilted dipole quasi-Yagi antenna designed for 3G and Bluetooth applications

Applications in 3G, WLAN and Bluetooth are actually the largest area in wireless communications, especially for antenna designers. Due to that, in this paper a broadband planar antenna based on the classic Yagi-Uda dipole antenna and projected to the range of frequencies that includes 1.8 GHz, 1.9 GHz, and 2.45 GHz is presented. This "tilted dipole, quasi-Yagi antenna" achieves a measured 41% bandwidth for VSWR<2 a directivity of 5.5 dBi and an efficiency of 70-85%. In addition, a comparison between this antenna and a classical quasi-Yagi is done. The agreements between simulated and measured results for return loss are satisfactory.
Sequestosome 1 Is Part of the Interaction Network of VAPB

VAPB (Vesicle-Associated-membrane Protein-associated protein B) is a tail-anchored membrane protein of the endoplasmic reticulum that can also be detected at the inner nuclear membrane. As a component of many contact sites between the endoplasmic reticulum and other organelles, VAPB is engaged in multiple protein interactions with a plethora of binding partners. A mutant version of VAPB, P56S-VAPB, which results from a single point mutation, is involved in a familial form of amyotrophic lateral sclerosis (ALS8). We performed RAPIDS (rapamycin- and APEX-dependent identification of proteins by SILAC) to identify proteins that interact with or are in close proximity to P56S-VAPB. The mutation abrogates the interaction of VAPB with many known binding partners. Here, we identify Sequestosome 1 (SQSTM1), a well-known autophagic adapter protein, as a major interaction/proximity partner of P56S-VAPB. Remarkably, not only the mutant protein, but also wild-type VAPB interacts with SQSTM1, as shown by proximity ligation assays and co-immunoprecipiation experiments.
Black & White Testing: Bridging Black Box Testing and White Box Testing.

Since the mid 1970s, software testing has been dominated by two major paradigms, known as black box testing and white box testing. Strategies for black box testing are based on the specification of the software component under test. Test suites developed using the black box paradigm reveal errors against the functional requirements of software components. Strategies for white box testing are based on the internals of software components. White box test suites are derived from the source code of the software component under test. Because programs can be represented in terms of graphs, solid coverage criteria can be defined for white box testing strategies. In this paper, we start with a brief overview of the principles underlying black box testing and white box testing. Hereafter, we propose a process for testing software components in which both paradigms are used at appropriate points in the software life cycle. We also touch upon the applicability of both paradigms in testing object-oriented programs.
60.3: Investigation on Viewing Angle Requirements and Glare with Respect to Size of Flat‐panel Television Displays

This paper summarizes the results of an investigation on the viewing angle requirements for large flat‐panel television displays as well as on screen tilting as a means of reducing glare in accordance with the “Ergonomic Design Guidelines for Flat Panel Display Televisions” established by a special committee of the Japan Ergonomics Society. First, taking into account screen size, we investigated viewing angle requirements through a field survey of household television viewing conditions. We then evaluated the influence of the size, mounting height, and tilt of the screen on the occurrence of glare. Next, we conducted laboratory experiments to investigate the allowable tilt angle for ensuring acceptable viewing comfort and the optimum screen tilt angle for each mounting height. The results can be used as guidelines for adjusting viewing conditions as well as for ergonomic design of flat‐panel television displays.
Magnetoelastic thin films and multilayers for high-frequency applications

Magnetoelastic and magnetic high-frequency properties of single and multilayer thin films are investigated with respect to applications in micro-inductors and as remote-interrogated sensors for mechanical quantities. The basic structure is a thin film inductor incorporating a magnetic material in order to enhance the inductance. In case of a sensor the inverse magnetostriction is used to change the permeability of the magnetic material and thus the inductance of the device. Materials properties like saturation magnetization, anisotropy field, resulting domain structures, electrical resistivity as well as the stress state of the films have to be adjusted carefully in order to meet certain requirements like high cut-off frequencies combined with low losses, and a high and controllable inverse magnetostrictive effect. In this paper (Fe-Co/Fe-Co- B-Si) multilayers are investigated in terms of their magnetic, high-frequency, and structural properties. (Fe50Co50Cp80B20) multilayers, e.g., have been fabricated which show ferromagnetic resonance frequencies up to 5 GHz while exhibiting a high inverse magnetostrictive effect up to the GHz frequency range. The obtained results for first LC circuits realized using (Fe50Co50/Co80B20) multilayers are discussed.
Combined Water Extracts from Oxidation-Treated Leaves and Branches of Hovenia dulcis Has Anti-Hangover and Liver Protective Effects in Binge Alcohol Intake of Male Mice

Hovenia dulcis, known as the oriental raisin tree, is used for food supplements and traditional medicine for the liver after alcohol-related symptoms. However, little information exists about the use of its leaves and branches. In this study, we established a method to use the leaves and branches to develop anti-hangover treatment and elucidated the underlying mechanisms. Oxidation-treated leaves (OL) exhibited high antioxidant content comparable to that of the peduncles and showed an anti-hangover effect in male mice. The branch extract (BE) was enriched in the flavonoid catechin, approximately five times more than OL extract. The mixture of OL and BE (OLB) was formulated in a 2:1 ratio with frozen-dried extract weight and was tested for anti-hangover effects and protective properties against binge alcohol-induced liver injury. OLB showed better anti-hangover effect than OL. In addition to this anti-hangover effect, OLB protected the liver from oxidative/nitrosative damage induced by binge alcohol intake.
Text Mining and Hub Gene Network Analysis of Endometriosis

This study is aimed at systematically characterizing the endometriosis-associated genes based on text mining and at annotating the functions, pathways, and networks of endometriosis-associated hub genes. We extracted endometriosis-associated abstracts published between 1970 and 2020 from the PubMed database. A neural-named entity recognition and multitype normalization tool for biomedical text mining was used to recognize and normalize the genes and proteins embedded in the abstracts. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses were conducted to annotate the functions and pathways of recognized genes. Protein-protein interaction analysis was conducted on the genes significantly cooccurring with endometriosis to identify the endometriosis-associated hub genes. A total of 433 genes were recognized as endometriosis-associated genes (P < 0.05), and 154 pathways were significantly enriched (P < 0.05). A network of endometriosis-associated genes with 278 gene nodes and 987 interaction links was established. The 15 proteins that interacted with 20 or more other proteins were identified as the hub proteins of the endometriosis-associated protein network. This study provides novel insights into the hub genes that play key roles in the development of endometriosis and have implications for developing targeted interventions for endometriosis.
Composting of < 100 mm Fraction of Municipal Solid Waste:

A low cost solution for management of municipal solid waste in small municipalities was investigated; composting experiments were done using domestic waste. Particles >100 mm were removed, the screened substrate (<100 mm) was used for composting experiments on static piles. The results have shown that the size of waste does not affect composting. Though the inert material left greatly adds to the porosity, rainfall does not markedly affect the process; in fact excessive dryness gave the least stable end product, and total nitrogen, ammoniacal nitrogen and phosphorus content were the best pointers to the instability.
A lifecycle‐based method for the acquisition of commercial‐off‐the‐shelf (COTS) technology to support organizational processes

Organizations are seeking commercial off‐the‐shelf (COTS) information technology (IT) solutions to enable the innovation of business processes. The ability to acquire IT should impact how an organization designs its processes. Likewise, the design of processes should influence which IT solutions are selected. Selecting IT solutions that support the business processes of an organization is critical for aligning IT with organizational goals. A formal decision process is needed to enable organizations to make an effective decision about which COTS IT solutions it acquires and shapes its organization around. The Stakeholder Life Cycle Method for COTS Solutions (SLIC) was developed to support the lifecycle‐based acquisition of COTS information technology (IT) solutions. A critical step in the lifecycle is the selection of COTS technology that will be used to enable the redesign of organizational processes. The SLIC method uses the IT requirements defined by a process model of the organization to create the criteria for the evaluation of potential IT solutions. The SLIC method was validated with a case study for a group of three newspaper publishing organizations located in southeastern Massachusetts. © 2001 John Wiley & Sons, Inc. Syst Eng 4: 287–304, 2001
Mortality prediction in chronic interstitial lung diseases (ILDs): ILD-GAP (gender age physiology) and (the new modified classification) TNMC-ILD-GAP

Abstract Introduction: The interstitial lung disease-gender age physiology (ILD-GAP) model has been proposed on the lines of GAP-idiopathic pulmonary fibrosis (IPF) to predict mortality in chronic ILDs, other than IPF. We replaced diffusion capacity of lung for carbon monoxide (DLCO) with the easy to perform 6-minute walk distance (6 MWD) in the ILD-GAP and proposed the new modified classification (TNMC)-ILD-GAP model. Our aim was to demonstrate the usefulness of the TNMC-ILD-GAP as a predictor of mortality in all chronic ILDs and compare the results with the ILD-GAP. Methods: It was a retrospective observational study conducted at a tertiary care centre. Baseline characteristics of the patients among different ILD groups were analysed. A 3-year follow-up was recorded. The results were compared with the original ILDGAP model. Chi-square and paired t-test was used for comparison of qualitative and quantitative data, respectively. Results: Mean ages were 62.34 (±9.85), 57.9 (±11.6), 46.1 (±14.6) and 55.5 (±14.7) in IPF, non-specific interstitial pneumonitis (NSIP), connective tissue disease (CTD) and unclassifiable groups, respectively. There were 50%, 18%, 26% and 55% males in the four categories respectively. Mean 6 MWD was 227 m, 302 m, 342 m, and 332 m. Mean PaO2 was 64 mmHg, 70 mmHg, 75 mmHg, 69 mmHg. Mean forced vital capacity (FVC) (percentage predicted) was 52, 49, 51 and 54. Most of the patients had comorbidities, among which pulmonary hypertension was the most common. Mortality with ILD-GAP model and TNMC-ILD-GAP showed concordant results as the difference in mortality predicted by ILD-GAP and the TNMC-ILD-GAP models was statistically insignificant (P > 0.050). Conclusion: 6 MWD can serve as a reliable replacement for DLCO in the ILD-GAP model, especially in resource limited settings.
Fake News: O Que É, Como Se Faz E Por Que Funciona?

This work presents a review about information disorder, amidst which we include the so-called “fake news” phenomenon. Due to its increased potential for propagation in digital age, false or malicious content has impacted political and social life and its consequences range from rejection of health recommendations to violent disorders. In this review, we first define information disorder, considering some theoretical distinctions between its different manifestations. We then address the processes of production and dissemination of false and malicious content, focusing the producers and also the channels thought which such materials are spread. Next, we discuss reception of false content, reviewing works on the psychological and cognitive bases of gullibility.

Balancing human–bear coexistence with biodiversity conservation

ABSTRACT Human–bear conflicts (HBC) impact the livelihoods and safety of local communities in underdeveloped areas and challenges local governments and wildlife conservation agencies. We conducted a systematic analysis of HBC in the Sanjiangyuan National Park, which is a core region of the Qinghai Tibet Plateau. This study consisted of semi-structured interviews with 81 stakeholders in October 2020, including local families and government departments. We qualitatively assessed the dominant characteristics and causes of bear damage in the region and proposed various mitigation strategies. The results revealed that recent implementations of biodiversity conservation and ecological restoration policies have increased the number and severity of HBC. Livestock depredation, attack on humans, and house break-ins were the most common and damaging conflict types. We discuss the challenges of HBC mitigation in the region and propose possible mitigation strategies based on the results of the interviews.
Spectral analysis of DC link ripple currents in three-phase AC/DC/AC PWM converters feeding AC machines

In this paper, DC link ripple currents for three-phase AC/DC/AC PWM converters feeding adjustable speed AC machine drives are analysed in a frequency domain. The expression of the harmonic currents is developed by using switching functions and exponential Fourier series expansion. The effect of the displacement angle between the switching periods of line-side converters and motor-side inverters on the DC link ripple currents is investigated. Also, the influence of asynchronization of PWM is observed. The result of analysis is compared with frequency spectrum which results from PSIM simulation.
PuMa, a digital Pulsar Machine

We have designed and constructed PuMa, a pulsar machine that has both a baseband recording and a digital lterbank mode. Its design is based on the use of digital signal processors (DSPs). Their operation is controlled by software, which makes PuMa recongurable, flexible and easy to operate. The maximum number of channels in the digital lterbank mode is 32 768 over a bandwidth of 80 MHz. This makes PuMa suitable for pulsar observations at low sky frequencies. The maximum bandwidth in baseband recording mode is two times 10 MHz. The machine was installed at the Westerbork Synthesis Radio Telescope in The Netherlands in 1998. We discuss in some detail PuMa's technical properties and capabilities. Recent observations, a sample of which are presented here, demonstrate its capabilities and that it is performing up to its specications.
Stochastic Prediction for Frost Heave Effect of a Subway Tunnel

Horizontal freezing induces ground frost heave and ground displacement happens. Excessive uneven displacement or deformation may be dangerous to the surrounding building. The stratum that a Nanjing subway tunnel will traverse through is the soft and silt clay. The artificial freezing construction method is proposed to help the tunnel to traverse through the worse stratum. To control the ground building deformation and displacement due to the ground frost heave, the frost heave effect for the artificial freezing construction should be predicted before the construction process. The stochastic media theory is proposed to predict the frost heave effect due to the artificial freezing construction in the paper. The basic analysis procedure for analyzing frost heave effect is introduced and ground deformations such as ground vertical displacement, ground curvature are analyzed. The analysis result shows that the ground deformation due to the frost heaves is in the limit of ground displacement control requirement.
Motivated Inferences of Price and Quality in Healthcare Decisions

Policy makers have increasingly advocated for healthcare price transparency, whereby prices are made salient before services are rendered. While such policies may empower consumers, they also bring price to the forefront of healthcare choices as never before, with yet underexplored consequences on consumers’ decisions. This article explores one: using price as a signal of quality. Five experiments demonstrate how healthcare consumers may come to form price-based inferences of quality and explore how these inferences may vary as a function of individuals’ health insurance coverage. Specifically, relative to high-coverage consumers (for whom insurance covers a relatively greater portion of healthcare expenses), low-coverage consumers (for whom insurance covers relatively less) tend to both choose lower-priced providers and perceive a weaker price-quality relationship, suggestive of motivated reasoning. Our work exposes one way in which price transparency policies may have divergent effects on low- versus high-coverage consumers, with direct implications for policy.
Developing a Novel Integrated Generalised Data Envelopment Analysis (DEA) to Evaluate Hospitals Providing Stroke Care Services

Stroke is the biggest cause of adult disability and the third biggest cause of death in the US. Stroke is a medical emergency, and the treatment given in the early hours is important in shaping the patient’s long-term recovery and prognosis. Despite the fact that substantial attention has been dedicated to this complex and difficult issue in healthcare, novel strategies such as operation research-based approaches have hardly been used to deal with the difficult challenges associated with stroke. This study proposes a novel approach with data envelopment analysis (DEA) and multi-objective linear programming (MOLP) in hospitals that provide stroke care services to select the most efficient approach, which will be a new experiment in literature perception. DEA and MOLP are widely used for performance evaluation and efficiency measurement. Despite their similarities and common concepts, the two disciplines have evolved separately. The generalised DEA (GDEA) cannot incorporate the preferences of decision-makers (DMs) preferences and historical efficiency data. In contrast, MOLP can incorporate the DM’s preferences into the decision-making process. We transform the GDEA model into MOLP through the max-ordering approach to (i) solve the problem interactively; (ii) use the step method (STEM) and consider DM’s preferences; (iii) eliminate the need for predetermined preference information; and (iv) apply the most preferred solution (MPS) to identify the most efficient approach. A case study of hospitals that provide stroke care services is taken as an example to illustrate the potential application of the proposed approach method.
Time-varying harmonics of single-phase nonlinear appliances

The paper deals with the time-variant behavior of harmonic currents produced by single-phase nonlinear (NL) appliances. The harmonic currents have been monitored in a broad field measurement activity that has concerned several samples of the more widespread appliance types in a power demand range up to hundreds of Watts. For the measurement activity a custom system allowing the continuous harmonic monitoring of voltage and current signals has been used. The results obtained show that for almost all the investigated appliances a not negligible variation of harmonic currents with time can be found. The possible causes of the observed behavior are discussed in detail. Finally, the utility of specific statistical and graphical tools for approaching the problem is discussed.
