Authors: Kearns William R. , Chi Nai-Ching , Choi Yong K. , Lin Shih-Yin , Thompson Hilaire , Demiris George 
Published: April 2020

Abstract
Background Health dialog systems have seen increased adoption by patients, hospitals, and universities due to the confluence of advancements in machine learning and the ubiquity of high-performance hardware that supports real-time speech recognition, high-fidelity text-to-speech, and semantic understanding of natural language.
Objectives This review seeks to enumerate opportunities to apply dialog systems toward the improvement of health outcomes while identifying both gaps in the current literature that may impede their implementation and recommendations that may improve their success in medical practice.
Methods A search over PubMed and the ACM Digital Library was conducted on September 12, 2017 to collect all articles related to dialog systems within the domain of health care. These results were screened for eligibility with the main criteria being a peer-reviewed study of a system that includes both a natural language interface and either end-user testing or practical implementation.
Results Forty-six studies met the inclusion criteria including 24 quasi-experimental studies, 16 randomized control trials, 2 case–control studies, 2 prospective cohort studies, 1 system description, and 1 human–computer conversation analysis. These studies evaluated dialog systems in five application domains: medical education (n = 20), clinical processes (n = 14), mental health (n = 5), personal health agents (n = 5), and patient education (n = 2).
Conclusion We found that dialog systems have been widely applied to health care; however, most studies are not reproducible making direct comparison between systems and independent confirmation of findings difficult. Widespread adoption will also require the adoption of standard evaluation and reporting methods for health dialog systems to demonstrate clinical significance.
Recent Advances in Pancreatic MR Imaging: A Guide on How, When, and Why to Perform
Authors: Srinivasan Sivasubramanian , Chatterjee Argha 
Published: April 2020

AbstractImaging of the pancreas is often challenging because of its retroperitoneal location and unique set of pathologies. Conventional imaging modalities, such as transabdominal and endoscopic ultrasonography (EUS), computed tomography (CT), and magnetic resonance imaging (MRI), are well described in the literature. However, with modern demand for functional and molecular information from imaging studies, newer imaging modalities and modifications of existing modalities are developed. MRI is widely used as a problem-solving tool in pancreatic pathologies. Magnetic resonance cholangiopancreatography (MRCP) is an excellent technique for the depiction of the pancreatic ductal or biliary ductal pathologies. Newer modification of MRI including secretin MRCP, advanced diffusion-weighted imaging (DWI), perfusion imaging, and tissue composition analysis (fat and fibrosis quantification) add to the arsenal of MRI of the pancreas. In this review, we discuss the evolution of MRI of the pancreas and clinical application of advanced MR sequences.

Published: April 2020

AbstractCerebro-costo-mandibular syndrome (CCMS) is a rare syndrome characterized by posterior rib ossification gaps and orofacial anomalies. Posterior rib ossification gaps are the hallmark of the disease and mimic multiple old rib fractures. The condition is caused by heterogeneous mutation of Small Nuclear Ribonucleoprotein Polypeptides B and B1 (SNRPB) gene on the chromosome 20p13. There is scanty literature regarding the extent of bony changes and the associated pulmonary-airway abnormalities on computed tomography (CT) imaging. In this case report, we presented a detailed CT imaging features of a case of CCMS in a male infant. This report highlighted on the nature of osseous defects, structural changes in the chest wall, airways, lungs, and a wide range of spinal anomalies. Some of our observations regarding the changes in the airway and chest wall are likely to have bearing on evaluating the prognosis and the need for respiratory support.
Tapping into science advisers’ learning
Authors: Obermeister Noam 
Published: April 2020

AbstractThe art and craft of science advice is not innately known by those scientists who choose to step out of the lab or the university to engage with the world of policy. Despite a wealth of literature on the ‘science of science advice’, in nearly every situation there is no ‘teacher’ of science advice; it is a typical case of learning on the job. Within that context, the learning of scholars engaging in expert advice is always situated and can sometimes be transformative. To date, however, there has been no systematic, in-depth research into expert advisers’ learning—instead focusing mostly on policymakers’ and publics’ learning about science. In this article, I suggest that such a research programme is timely and potentially a very fruitful line of inquiry for two mains reasons. First, in the case of environmental and climate issues—the focus of the paper—it has become ubiquitous to talk about the need for transformative change(s) towards sustainable futures. If scholars are going to advocate for and inform transformations beyond academia, then in doing so they ought to also take a harder look at how they themselves are transforming within. Specifically, the article illustrates how qualitative research on advisers’ learning can contribute to our understanding of how experts are adapting to changing circumstances in science–policy interactions. Second, it is argued that research on advisers’ learning can directly contribute to: (i) guidance for present and future advisers (especially early-career researchers wishing to engage with policy) and organisational learning in science–policy organisations; and (ii) improving policy-relevance of research and the design of impact evaluations for research funding (e.g. Research Excellence Framework). With the hope of stimulating (rather than closing off) innovative ideas, the article offers some ways of thinking through and carrying out such a research programme. As the nature of both science and policymaking continues to change, the learning experiences of expert advisers is a bountiful resource that has yet to be tapped into.
All-electrical monitoring of bacterial antibiotic susceptibility in a microfluidic device
Authors: Yang Yichao , Gupta Kalpana , Ekinci Kamil L. 
Published: April 2020

SignificanceFor the past 50 y, antibiotics have cured common bacterial infections quickly and effectively. Many strains of bacteria, however, are gaining resistance to common antibiotics. The solution to this problem includes a more judicious use of antibiotic therapies, directed by rapid point-of-care antibiotic susceptibility tests. The focus here is a simple all-electrical sensing approach implemented in a microfluidic device that measures the growth of a tiny bacteria sample in antibiotics. This approach has the potential to rapidly provide antibiotic susceptibility of bacteria along with minimum inhibitory concentrations and inform of the mechanisms of action of antibiotics—all without resorting to high-resolution microscopy.

Published: April 2020

Background and Aims: Little is known about how the expansion of opioid agonist therapy (OAT) and emergence of fentanyl in the illicit drug supply in North America has influenced non-fatal opioid overdose (NFOD) risk. Therefore, we sought to identify patterns of substance use and addiction treatment engagement (i.e., OAT, other inpatient or outpatient treatment) prior to NFOD, as well as the trends and correlates of each pattern among people who use drugs (PWUD) in Vancouver, Canada. Methods: Data were derived from participants in three prospective cohorts of PWUD in Vancouver in 2009–2016. Observations from participants reporting opioid-related NFOD in the previous six months were included. A latent class analysis was used to identify classes based on substances used at the time of last NFOD and addiction treatment engagement in the month prior to the last NFOD. Multivariable generalized estimating equations estimated the correlates of each class membership. Results: In total, 889 observations from 570 participants were included. Four distinct classes were identified: (1) polysubstance use (PSU) and addiction treatment engagement; (2) PSU without treatment engagement; (3) exposure to unknown substances, mostly without treatment engagement; and (4) primary heroin users without treatment engagement. The class of exposure to unknown substances appeared in 2015 and became the dominant group (76.9%) in 2016. In multivariable analyses, the odds of membership in the class of primary heroin users decreased over time (adjusted odds ratio [AOR]: 0.74, 95% confidence interval [CI]: 0.68–0.81). Conclusions: Changing profiles of PWUD reporting opioid-related NFOD were seen over time. Notably, there was a sudden increase in reports of overdose following exposure to unknown substances since 2015, the majority of whom reported no recent addiction treatment engagement. Further study into patterns of substance use and strategies to improve addiction treatment engagement is needed to improve and focus overdose prevention efforts.
Transverse-to-longitudinal emittance-exchange in optical wavelength
Authors: Wang Xiaofan , Feng Chao , Yang Chuan , Zeng Li , Zhao Zhentang 
Published: April 2020

Abstract
Emittance exchange is a promising technique for next-generation accelerator-based applications. A novel technique is proposed in this paper to exchange emittance of the electron beam between transverse and longitudinal planes in optical wavelength. The emittance exchange configuration consists of a dual-tilted-laser modulator sandwiched by two identical doglegs. Analytical and simulation results demonstrate that the emittance exchange for the electrons at the zero-crossing phase of each laser cycle can be easily achieved with this technique. The proposed technique is quite promising for improving the performance of compact high-gain free-electron laser facilities. Meanwhile, it holds the feasibility to flexibly tailor a beam’s longitudinal shape in the optical scale.

Using methodologies of AHP Evaluation Model, Co-Integration Analysis, Granger Causality Test and Error Correction Model etc., this paper makes the empirical studies on the relations between environmental protection investment, industrial pollution control, urban environment construction, natural resources conservation and the ecological environment construction in Shandong Province. Our research found that: the overall level of ecological environment construction in Shandong province has been constantly and steadily enhanced, among which the level of urban environment construction has risen the most, followed by environmental protection investment, industrial pollution control and natural resources conservation. Besides, there is a long-term equilibrium relation between the ecological environment construction and economic growth of Shandong Province, among which the bidirectional synergistic effect on the environmental protection investment and economic growth of eastern Shandong is the most remarkable. Therefore, this paper puts forward countermeasures and suggestions, for example, implementing ecological development policies towards spatial differences, improving the ecological environment management, actively implementing environmental economic policies etc.

Published: April 2020

Abstract
In order to study the effects of alginic acid at different dilution folds on phosphorus and potassium absorption of radish under cadmium contamination, foliar application of radish seedlings was carried out using alginic acid solutions with different dilution folds. The results showed that the alginic acid solution at 600, 900, 1200, and 1500 dilution folds increased the potassium content of radish, and increased the content of available phosphorus and available potassium in the soil. The solution of lower dilution folds (600 and 900) increased phosphorus content of radish, while the solution with higher dilution folds (1200 and 1500) only increased phosphorus content in radish roots and root tubers. It showed that foliar application of alginic acid could alleviate the harm of cadmium stress to radish to a certain extent, and increase the absorption of phosphorus and potassium nutrients in radish. The best effect was achieved when the dilution fold of alginic acid solution was 600.

Authors: Wang Chenglin , Shan Jinling , Shuhong LI 
Published: April 2020

Abstract
Underfloor Air Distribution (UFAD) systems have received increasing attention during the past decades due to thermal stratification and energy saving potential over conventional mixed air conditioning system. Different supply air parameters have significant impacts on the UFAD system performance. In this study, experimental study and energy simulation software EnergyPlus were used to investigate the UFAD performance in a full size experimental room. The distance between diffusers and human, supply air temperature and velocity were discussed. The orthogonal experiments were employed to discuss the effect of supply air parameters on the temperature distribution, thermal comfort and indoor air quality (IAQ). By the analysis, the most important factor is the distance between diffusers and human. Furthermore, the preferable supply air parameters are suggested by means of controlling parameters. The results show that better thermal stratification and thermal comfort can be achieved when the distance between the swirl diffusers and human is 0.7m, the Supply Air Temperature (SAT) is 18-20°C and the Supply Air Velocity (SAV) is 1.2-1.5m/s. Another contribution of this paper is that the energy consumption of UFAD system is calculated by EnergyPlus. The calculation shows that the satisfied thermal stratification and prominent energy saving can be achieved simultaneously by using reasonable supply air parameters, such as the SAT is 18°C and the SAV is 1.2m/s.
Reactive power optimization of dynamic power system based on QPSO algorithm
Authors: Ang Dong , Xin Song 
Published: April 2020

Abstract
During the operation of the power system, there is a certain loss when electrical energy transmitting through the line, The losses in the line are usually dominated by active network losses. The current research mainly uses reactive power optimization to reduce the reactive power loss in the system. Traditional reactive power optimization is optimized for a certain static time, and the state of the equipment in the line does not change, which is meaningless for actual engineering.A full-text optimization model is established for the purpose of reducing active network loss. The QPSO algorithm is used to dynamically optimize the load of a certain place for different periods of time. Based on the optimization results, we control the the operating status to reduce the active network loss in the line.
Experience and enlightenment of water conservancy project investment
Authors: Wang Xifeng 
Published: April 2020

Abstract
This paper summarizes and studies the investment and financing policies of water conservancy related projects in the USA, Japan, Australia, India and Brazil, and then analyses the enlightenment of these policies to such areas reform in China. According to the researches, the U.S. government has increased to broaden financing channels, and local governments, collective and private non-federal government agencies are the main body of financing. Japan’s domestic water conservancy projects are mainly undertaken by domestic water conservancy related development and construction companies. The design and construction of most water conservancy projects in the six major water systems in Japan are mainly undertaken by the Japanese water resources development group. In Australia, water resources and other related resources are in the charge of each state, so water conservancy projects are also in the charge of each state, and the federal government and local government manage them at the same time. For all kinds of small-scale water conservancy facilities, the Indian government encourages private investors to invest, operate and manage them. Brazil has a large investment in domestic large and medium-sized water conservancy projects, for which the federal government has made great efforts in investment and financing. Therefore, China government should make a reasonable distinction between public and non-public water conservancy projects and adopt different investment policies, and should make clear the rights, responsibilities and interests of the investors and beneficiaries, make clear the property rights, and establish an effective project legal person system.

Published: April 2020

Abstract
In this work, imidazoline-palmitic derivative had been successfully synthesized by reacting triethylenetetramine (TETA) with palmitic acid (PA). Synthesis process was performed with solvent free using MAOS (Microwave Assisted Organic Synthesis) method with variation of time reactions. Dean-Stark and reflux methods using xylene as a solvent were also performed as comparisons. The percentage yield of TETA-PA imidazoline was obtained from Dean-Stark at 13 hours (95.80 %), reflux at 13 hours (88.53 %), and MAOS at 11 min (87.74 %). TETA-PA imidazoline then was identified by using thin layer chromatography and melting point analyzer followed by characterization using Fourier Transform Infrared (FTIR), UV-Vis, Proton Nuclear Magnetic Resonance (1H-NMR), and Mass Spectrometry (MS) spectral data. This study provides information regarding comparison method for imidazoline derivative synthesis. For further research, TETA-PA imidazoline can be used as corrosion inhibitor towards carbon steel.

Published: April 2020

Abstract
Microspheres of poly(lactic acid) (PLA) and poly(ε-caprolactone) (PCL) were blended and prepared using the water in oil (w/o) emulsion solvent evaporation method. The PLA/PCL blend was formulated with the composition of 60:40 (w/w), nonionic surfactant was utilized as the emulsifier. This study observed the distribution of the microspheres particle size by varying the nonionic surfactant volumes, emulsion stirring speed, and dispersion stirring time. The microspheres were characterized using Fourier Transform Infrared (FTIR) and Particle Size Analyzer (PSA). Physical forms of microspheres were observed using an optical microscope as well. The IR spectra of PLA/PCL blend showed that only physical interaction was occured between them. Moreover, the result of this study showed that when 2.0 mL nonionic surfactant was added, the uniform size distribution of the formed microspheres was observed at 31.50µm. Furthermore, the microspheres that formed through emulsion stirring speed at 900 rpm revealed that the formed microspheres have a uniform size distribution at 31.50 μm, while the uniform size distribution at 34.58 μm was observed in the microspheres that formed during the dispersion stirring time at 90 minutes.
