Deep Learning for Price Movement Prediction Using Convolutional Neural Network and Long Short-Term Memory
Authors: Yang Can , Zhai Junjie , Tao Guihua
Published: July 2020

The prediction of stock price movement direction is significant in financial studies. In recent years, a number of deep learning models have gradually been applied for stock predictions. This paper presents a deep learning framework to predict price movement direction based on historical information in financial time series. The framework combines a convolutional neural network (CNN) for feature extraction and a long short-term memory (LSTM) network for prediction. We specifically use a three-dimensional CNN for data input in the framework, including the information on time series, technical indicators, and the correlation between stock indices. And in the three-dimensional input tensor, the technical indicators are converted into deterministic trend signals and the stock indices are ranked by Pearson product-moment correlation coefficient (PPMCC). When training, a fully connected network is used to drive the CNN to learn a feature vector, which acts as the input of concatenated LSTM. After both the CNN and the LSTM are trained well, they are finally used for prediction in the testing set. The experimental results demonstrate that the framework outperforms state-of-the-art models in predicting stock price movement direction.

Published: July 2020

In this paper, the question of when the subdirect sum of SDD1 matrices is in the class of SDD1 matrices is studied. Some sufficient conditions are given. Moreover, these sufficient conditions only depend on the elements of given matrices; thus, they provide some simple criteria for application. Numerical examples are also presented to illustrate the corresponding results.

Objective. With the growing incidence of ischemic stroke worldwide, there is an urgent need to identify blood biomarkers for ischemic stroke patients. Thus, our aim was to identify potential circulating microRNA (miRNA) as a potential biomarker and to explore its potential mechanism for ischemic stroke in rats. Methods. The mRNA dataset GSE97537 and miRNA dataset GSE97532 were downloaded from the Gene Expression Omnibus (GEO) GSE97537 including 7 middle cerebral artery occlusion (MCAO) rat brain tissues and 5 sham‐operated rat brain tissues GSE97532 including 6 MCAO rat blood samples and 3 sham‐operated rat blood samples. Differentially expressed mRNAs and miRNAs with corrected p value ≤ 0.01 and fold change ≥2 or ≤0.05 were identified. To explore potential biological processes and pathways of differentially expressed mRNAs, functional enrichment analysis was performed. The target mRNAs of differentially expressed miRNAs were predicted using DNA Intelligent Analysis (DIANA)‐microT tools. The target mRNAs and differentially expressed mRNAs were intersected. Results. 1228 differentially expressed mRNAs in MCAO rat brain tissues were identified. Highly expressed mRNAs were mainly enriched in the inflammatory responses. Nine differentially expressed miRNAs were identified in MCAO rat blood samples. A total of 673 target mRNAs were predicted to significantly bind these differentially expressed miRNAs. Among them, 54 target mRNAs were differentially expressed in MCAO rat blood samples. Enrichment analysis results showed that these 54 target mRNAs were closely related to neurological diseases and immune responses. Among all miRNA‐mRNA relationship, miR‐3552‐CASP3 interaction was identified, indicating that CASP3 might be mediated by miR‐3552. Functional enrichment analysis revealed that CASP3 was involved in the apoptosis pathway, indicating that miR‐3552 might participate in apoptosis by CASP3. Conclusion. Our findings reveal that circulating miR‐3552 shows promise as a potential biomarker for ischemic stroke in rats.
Effect of Coalbed Methane Well Fracturing on Slope Stability of Open‐Pit Coal Mine: A Case Study of Shengli East No. 2 Open‐Pit Coal Mine

Published: July 2020

The impact of hydraulic fracture from CBM well fracturing on slope stability of the Shengli East No. 2 open‐pit coal mine is analyzed by numerical simulation and limit equilibrium methods. The interference effect of coalbed methane (CBM) well fracturing on slope stability of the open‐pit coal mine promotes the coordinated development of CBM, and open‐pit coal is discussed before and after coal mining. It shows that nearly horizontal fractures are formed in the coal seam due to CBM well fracturing, of which the dynamic facture length and propping fracture length are 137.2 m and 105.2 m, respectively. Moreover, the dynamic fracture height is 137.2 m and propping fracture height is 130.6 m. At the location of perforation, the dynamic fracture width is 0.873 cm and average propping fracture width is 0.111 cm. The CBM well fracturing barely imposed any effect on slope stability before open‐pit coal mining. The maximum vertical displacement at the toe of slope induced by fracturing is 0.293 mm. In situations with and without CBM well fracturing, vertical stress distributions in the toe, top, and interior of slope have no obvious difference. There is some extent of vertical stress increase within the interior of slope, which is merely 0.2 MPa higher than that in the condition of initial in situ stress equilibrium. The presence of hydraulic fractures has little effect on the overall displacement of slope during coal mining; and there is no obvious difference between the slope stability during coal mining and the slope stability impacted by fracturing. According to the results of limit equilibrium method and numerical simulation, the overall slope stability coefficient is 1.5–1.97, which accords with the requirements of the Design Code for Open-Pit Mine of Coal Industry (GB50197-2015). Therefore, more attentions should be paid to the ways of excavation and sloping during coal mining, avoiding slope instability caused by excavation.
Aerodynamic Design Optimization of Transonic Natural-Laminar-Flow Airfoil at Low Reynolds Number
Authors: Li Jing , Wang Cong , Bian Huiting
Published: July 2020

The position and size of laminar separation bubble on airfoil surfaces exert a profound impact on the efficiency of transonic natural-laminar-flow airfoil at low Reynolds number. Based on the particle swarm algorithm, an optimization methodology in the current work would be established with the aim of designing a high and robust performance transonic natural-laminar-flow airfoil at low Reynolds number. This methodology primarily includes two design processes: a traditional deterministic optimization at on-design point and a multi-objective of uncertainty-based optimization. First, a multigroup cooperative particle swarm optimization was used to obtain the optimal deterministic solution. The crowing distance multi-objective particle swarm optimization and the non-intrusive polynomial chaos expansion method were then adopted to determinate the Pareto-optimal front of uncertainty-based optimization. Additionally, the γ−Re¯θt transition model was employed to predict the laminar-turbulent transition. Regarding to the established optimization methodology, a propeller tip airfoil of solar energy unmanned aerial vehicle was finally designed. During optimization processes, the minimized pressure drag was particularly chosen as the optimization objective, while the friction drag increment served as a constraint condition. The deterministic results indicate that the optimized airfoil has a good ability to control the separation and reattachment positions, and the pressure drag can be greatly reduced when the laminar separation bubble is weakened. The multi-objective results show that the uncertainty-based optimized airfoil possesses a significant robust performance by considering the uncertainty of Mach number. The findings evidently demonstrate that the proposed optimization methodology and mathematical model are valuable tools to design a high-efficiency airfoil for the propeller tip.
Curing Temperature Effects on the Tensile Properties and Hardness of γ −Fe2O3 Reinforced PDMS Nanocomposites
Authors: Konku-Asase Yvonne , Yaya Abu , Kan-Dapaah Kwabena
Published: July 2020

The mechanical properties of plain polydimethylsiloxane (PDMS) and its nanocomposites have been exploited for various theranostic biomedical applications. Although several research groups have investigated the effects of preparation conditions—especially curing temperature and time—on bulk mechanical properties of plain PDMS, there are no reported similar studies for its nanocomposites. In this study, mechanical properties of PDMS reinforced by different volume fractions (ϕmnp = 0–2 vol. %) of γ‐Fe2O3 nanoparticles (NPs) were investigated and quantitative data presented for different curing temperatures (25, 100, and 150°C). To a large extent, γ‐Fe2O3 NPs were uniformly dispersed in the PDMS matrix with no primary chemical bonds formed. For the temperatures tested, the data showed an increase for Young’s modulus (E) of about 170% (1.36–3.71 MPa) and a decrease of the ultimate tensile strength (UTS) of about 65% (6.48–2.93 MPa) with increasing concentration of the NPs. Furthermore, hardness (Shore A) (H) increased with curing temperature but decreased with concentration. Based on the findings, we conclude that the linear relationship between the calculated mechanical properties (E, UTS, H) and small ϕmnp is independent of the curing temperature. The experimental data provide useful background information for the selection of processing parameters for PDMS nanocomposite fabrication.
Finite Element Simulation of NiTiNb Shape Memory Alloy Pipe‐Joint Subjected to Coupled Transformation and Plastic Deformation
Authors: Chen Xiang , Chen Bin , Peng Xianghe , Jin Xiaoqing , Ma Ying , Zhao Yang , Zheng Hengwei
Published: July 2020

The assembling process of Ni47Ti44Nb9 alloy pipe joints considering the phase transformation and plasticity was numerically simulated for the first time with a developed constitutive model. The simulated process was based on the experimental material parameters, which were determined with the experimental tensile results of Ni47Ti44Nb9 shape memory alloy (SMA) and steel bars. The results showed that, after assembly, the Mises stress distributed uniformly along the longitudinal direction of the NiTiNb joint, but nonuniformly along the radial direction. The maximum σeq does not appear at the inner wall of the joints due to the coupling effect of the plastic deformation and the recoverable transformation. The contact pressure distributed uniformly along the circumferential direction, but nonuniformly along the longitudinal direction. The sizes of the SMA joint and the pipe should be properly matched to ensure contact during the stage of the rapid reverse phase transformation to obtain stable connection performance. The pull‐out force was also computed, and the results were in good agreement with the experimental results. The results obtained can provide available information for the optimization of the design parameters of the high‐performance SMA pipe‐joint, such as inner diameter and assembly clearance.

Macaca fuscata displays characteristic behaviours, such as stone handling, locomotor behaviour, gait position, and intermittent bipedalism. Differences in characteristic behaviours among primate species/genera could be explained by anatomical details of the body. However, the anatomical details have not been well studied in Macaca fuscata. Arterial models could be one of the anatomical bases for the phylogenetic and functional differences among species, since the arterial supply could be associated with the muscular performance, especially locomotor behaviour. In this study, five thoracic limbs of Macaca fuscata adults were dissected to analyse the vessels. Patterns of arterial distribution in the thoracic limbs of Macaca fuscata were compared with those in other primates. The results indicated that the arterial distribution in the Japanese monkeys was more similar to those in Macaca mulatta and Papio anubis, which is consistent with phylogenetic similarities. However, compared with Papio anubis and other macaques, there were anatomical differences in several points, including (1) the origin of the common, anterior, posterior circumflex, and profunda brachii, and (2) the origins of the collateralis ulnaris artery. The comparative anatomy of the arteries in the forelimb of Macaca fuscata, along with the anatomical studies in other primates, indicated characteristic patterns of brachial artery division and the number of the palmar arches in primates, which is consistent with the phylogenetic division among New World primates, Old World primates, and apes.
Radial Vibration Characteristics of Piezoelectric Ceramic Composite Ultrasonic Transducer
Authors: Yao Chundong , Zhang Chao , Zhang Jiani , Zhang Yang
Published: July 2020

Different from the existing equivalent circuit analysis method of the transducer, based on the vibration theory of the mechanical system and combined with the constitutive equation, this paper analyzes the radial vibration characteristics of the transducer. The piezoelectric ceramic composite ultrasonic transducer is simplified as a mechanical model of a composite thick wall tube composed of a piezoelectric ceramic tube and a metal prestressed tube. The mathematical model of radial vibration of the transducer is established, which consists of the wave equation of radial coupling vibration of the piezoelectric ceramic tube and the metal prestressed tube, the continuity conditions, and the boundary conditions of radial vibration of composite thick wall tube. The characteristic equation and the mode function of radial vibration are derived. The calculated results of natural frequency are in good agreement with the existing experimental results. Based on the analytical method and the difference method, the numerical simulation models of radial vibration are established, and the amplitude-frequency characteristic curves and the displacement responses are given. The simulation results show that the amplitude-frequency characteristic curves and the displacement responses of the two methods are the same, which verifies the correctness of simulation results. Through the simulation analysis, the influence rule of the transducer’s structure sizes on its radial vibration natural frequency is given: when the thickness of the metal prestressed tube and the piezoelectric ceramic tube are constant, the natural frequency decreases with the increase of the inner diameter of the piezoelectric ceramic tube; when the outer diameter of the metal prestressed tube and the inner diameter of the piezoelectric ceramic tube are constant, the natural frequency decreases with the increase of the thickness-to-wall ratio. The calculation method of natural frequency based on elastic vibration theory is clear in concept and simple in calculation, and the simulation models can analyze the mechanical vibration of the transducer.
Changes in Background Liver Function in Patients with Hepatocellular Carcinoma over 30 Years: Comparison of Child-Pugh Classification and Albumin Bilirubin Grade
Authors: Kumada Takashi , Toyoda Hidenori , Tada Toshifumi , Yasuda Satoshi , Tanaka Junko
Published: July 2020

Background: Background liver function in patients with hepatocellular carcinoma (HCC) has improved remarkably with advances in various treatments. Recently, the Child-Pugh classification (CPC) system has been recognized as limited in its ability to assess patients with good hepatic reserve. We compared the albumin-bilirubin (ALBI) grade, which is suitable for a more detailed evaluation of patients with good liver function, with CPC over a 30-year period. Methods: A total of 2,347 patients were analyzed. Patients were stratified by year of diagnosis into 6 groups: Group A (1990–1994, n = 376), Group B (1995–1999, n = 434), Group C (2000–2004, n = 438), Group D (2005–2009, n = 444), Group E (2010–2014, n = 392), and Group F (2015–2018, n = 263). We compared ALBI grade and CPC across the groups. Results: The prevalence of patients with CPC A at diagnosis increased throughout the study period, reaching nearly 80% in Groups E and F (p < 0.001). By contrast, the percentage of patients with ALBI grade 1 disease remained approximately 50% in Groups E and F (p < 0.001). Modified ALBI (mALBI) grade 2a corresponds to patients with CPC A who have poor hepatic function. There were significant survival differences between patients with mALBI grade 1 versus 2a, 1 versus 2b, and 2a versus 2b disease, respectively (p < 0.0001), in patients with CPC A. Conclusions: CPC is not suitable for assessing patients with recently diagnosed HCC and good remnant hepatic function. In such patients with HCC, the prognosis can be stratified by ALBI grade rather than CPC.

Aim: To describe architecture and expression of myosin isoforms of the human cremaster muscle (CM) and to individuate changes in clinically differentiated abnormalities of testicular descent: cryptorchidism or undescended testis (UDT) and retractile testis (RT). Background: The CM is a nonsomitic striated muscle differentiating from mesenchyme of the gubernaculum testis. Morphofunctional and molecular peculiarities linked to its unique embryological origin are not yet completely defined. Its role in abnormalities of testicular descent is being investigated. Subjects and Methods: Biopsy samples were obtained from corrective surgery in cases of cryptorchidism, retractile testis, inguinal hernia, or hydrocele. Muscle specimens were processed for morphology, histochemistry, and immunohistology. Results and Conclusions: The CM differs from the skeletal muscles both for morphological and molecular characteristics. The presence of fascicles with different characterization and its myosinic pattern suggested that the CM could be included in the specialized muscle groups, such as the extrinsic ocular muscles (EOMs) and laryngeal and masticatory muscles. The embryological origin from the nonsomitic mesoderm is, also for the CM, the basis of distinct molecular pathways. In UDT, the histological alterations of CM are suggestive of denervation; the genitofemoral nerve and its molecular messengers directed to this muscle are likely defective. Compared with the other samples, RT has a distinct myosinic pattern; therefore, it has been considered a well-defined entity with respect to the other testicular descent abnormalities.

Published: July 2020

Castleman disease is a rare cause of retroperitoneal mass in children. Clinical presentation and laboratory findings are usually nonspecific. Imaging shows features of a hypervascular or soft tissue mass. We present a 12-year-old boy who complained of frequent colds, fatigue, and failure to gain weight for the past 4 years who was referred to our hospital. Anemia and hypergammaglobulinemia were revealed in laboratory tests. Imaging showed a well-delineated retroperitoneal soft tissue mass with intense homogenous enhancement at the midline below the aortic bifurcation. The histopathological features were consistent with mixed type unicentric Castleman disease. Surgical removal was curative. Our patient’s hematological abnormalities resolved, and he gained 10 kg in the next 4 weeks after the operation and reached the 25–50th percentile for his age.
Estamira e os frágeis limiares heterotópicos de resistência à psiquiatria enquanto estratégia de governo biopolítico das diferenças
Authors: Soares Silvio De Azevedo
Published: July 2020

O objetivo deste trabalho é averiguar as probabilidades de resistência à psiquiatria – enquanto um dispositivo biopolítico de governo das diferenças – presente nas falas e na existência da personagem Estamira, reproduzidas no documentário homônimo. Em termos metodológicos, utilizando as reflexões de Foucault e Butler, tomo Estamira como um documentário de inspiração genealógica, que permite a manifestação do discurso sujeitado e a apreensão das condições precárias da personagem – que sujeita-se e resite aos governos religioso, familiar (como instância de normalização disciplinar e psiquiátrica do sujeito) e médico-psiquiátrico de sua existência. Ao estabelecer-se em um lixão (enquanto um espaço heterotópico), essa mulher classificada como louca e diagnosticada como esquizofrênica apresenta, de maneira paradoxal, uma resistência mais lúcida e crítica contra as investidas do poder psiquiátrico.

Published: July 2020

Background and Purpose:

Social determinants of health (SDOH) have been previously associated with incident stroke. Although SDOH often cluster within individuals, few studies have examined associations between incident stroke and multiple SDOH within the same individual. The objective was to determine the individual and cumulative effects of SDOH on incident stroke.

Methods:

This study included 27 813 participants from the REGARDS (Reasons for Geographic and Racial Differences in Stroke) Study, a national, representative, prospective cohort of black and white adults aged ≥45 years. SDOH was the primary exposure. The main outcome was expert adjudicated incident stroke. Cox proportional hazards models examined associations between incident stroke and SDOH, individually and as a count of SDOH, adjusting for potential confounders.

Results:

The mean age was 64.7 years (SD 9.4) at baseline; 55.4% were women and 40.4% were blacks. Over a median follow-up of 9.5 years (IQR, 6.0–11.5), we observed 1470 incident stroke events. Of 10 candidate SDOH, 7 were associated with stroke (
P
<0.10): race, education, income, zip code poverty, health insurance, social isolation, and residence in one of the 10 lowest ranked states for public health infrastructure. A significant age interaction resulted in stratification at 75 years. In fully adjusted models, among individuals <75 years, risk of stroke rose as the number of SDOH increased (hazard ratio for one SDOH, 1.26 [95% CI, 1.02–1.55]; 2 SDOH hazard ratio, 1.38 [95% CI, 1.12–1.71]; and ≥3 SDOH hazard ratio, 1.51 [95% CI, 1.21–1.89]) compared with those without any SDOH. Among those ≥75 years, none of the observed effects reached statistical significance.

Conclusions:

Incremental increases in the number of SDOH were independently associated with higher incident stroke risk in adults aged <75 years, with no statistically significant effects observed in individuals ≥75 years. Targeting individuals with multiple SDOH may help reduce risk of stroke among vulnerable populations.

In the note, the author focuses on the additional drawing made by an unknown reader on the miniature of the Old Rus’ illuminated manuscript of the Tale of the Route of Mamai. The drawing depicts the image of the Mandylion over one of the key scenes of the Tale: Dmitry Donskoy receiving the blessing and prosphoron from St Sergius of Radonezh. The author examines both, the text, that is illustrated, which cites the monastic rite of Panagia, and the symbolism of the image of the Holy Saviour Not Made by Hands, to conclude whether the addition was accidental or not.
Urgenda: the Final Judgment of the Dutch Supreme Court
Authors: Backes C.W. (Chris) , van der Veen G.A. (Gerrit)
Published: July 2020

The final verdict to the Urgenda case provided by the Dutch Supreme Court has been called a victory in the fight to limit climate change and a milestone in public interest litigation, at least in the Netherlands. As a consequence, the Dutch state will have to reduce ghg-emissions by 25% compared with 1990 at the end of 2020. The judgment has attracted widespread acclaim for being ‘courageous’ and exploring unknown legal territory. However, a closer look at the reasoning of the Court of Appeal and the Supreme Court still leaves many questions, which are address in this manuscript.

This article (re-)considers a unique Qurʾān manuscript (MS London, SOAS, 12217) in ciphered characters (Ar. al-taʿmiya), reminiscent of the ring letters of the Graeco-Egyptian tradition (Brillenbuchstaben). The case of this Qurʾān manuscript offers an opportunity to decode (Ar. istikhrāj al-muʿammà) a cryptographed text, to date and localize a very special Quranic codex, and to investigate the history of the collections it passed through, as well as the religious and cultural context of its production. Lastly, it examines the relations between Islam and magic—with which cryptography is often associated.
A Case Study for Culturally Responsive Teaching in Glodok, Jakarta, Indonesia: the Negotiation of Identity and Instruction for a Chinese-Indonesian Educator
Authors: Douglas Cynthia M.
Published: July 2020

This paper documents what culturally responsive teaching means for a teacher who is a member of a minority community of ethnic Chinese in Glodok (Chinatown), Jakarta, Indonesia. Culturally responsive teaching (CRT) in Indonesia has traditionally meant implementing an indigenous, Javanese-centered curriculum where ethic Chinese identity was disparaged. The data collected in this study illustrates how an educator must negotiate identity and instruction of CRT to students of her own ethnic group with whom she does not share a cultural identity. The broader significance of this study is understanding how educators from marginalized or minority communities are vital to the creation of dialogue within the constructs of culturally responsive teaching. This study illustrates the necessity to not make assumptions that educators from culturally and linguistically diverse communities are naturally predisposed to engage in CRT; this reinforces the urgency that all teachers need proper training in order to effectively employ culturally responsive teaching regardless of ethnicity, race, or culture.

Published: July 2020

Anoplistes kaszabi sp. nov. is described from Mongolia. Distinguishing characters from closely related Anoplistes mongolicus Ganglbauer, 1889 are presented and their ecological dissimilarity is discussed. High-quality stacked photographs of the habitus of the specimens are presented for both species and their geographical distributions are mapped. The new species differs from A. mongolicus mainly by the more elongate pronotum with different sculpture, the more evenly and densely pubescent elytra, the slender body of smaller size in both sexes, as well as by the different shape of female antennomeres. Additionally, they are most likely associated with two different host plants. Moreover, Anoplistes amoenus Reitter, 1898 (stat. res.) is herein restored to specific rank due to its clear distinctness compared to the discussed taxa.

Seasonal Forecast of Early Summer Rainfall at Stations in South China Using a Statistical Downscaling Model
Authors: Lu Zheng , Guo Yan , Zhu Jiangshan , Kang Ning
Published: July 2020

Current dynamic models are not able to provide reliable seasonal forecasts of regional/local rainfall. This study aims to improve the seasonal forecast of early summer rainfall at stations in South China through statistical downscaling. A statistical downscaling model was built with the canonical correlation analysis method using 850-hPa zonal wind and relative humidity from the ERA-Interim reanalysis data. An anomalous southwesterly wind that carries sufficient water vapor encounters an anomalous northeasterly wind from the Yangtze River, resulting in a wet anomaly over all of South China. This model provided good agreement with observations in both the training and independent test periods. In an independent test, the average temporal correlation coefficient (TCC) at 14 stations was 0.52, and the average root-mean-square error was 21%. Then, the statistical downscaling model was applied to the Climate Forecast System, version 2 (CFSv2), outputs to produce seasonal forecasts of rainfall for 1982–2018. A statistical downscaling model improved CFSv2 forecasts of station rainfall in South China with the average TCC increasing from 0.14 to 0.31. Forecasts of South China regionally averaged rainfall were also improved with the TCC increasing from 0.11 to 0.53. The dependence of forecast skill for regional average rainfall on ENSO events was examined. Forecast error was reduced, but not statistically significant, when it followed an El Niño event in both CFSv2 and the downscaling model. While when it followed an EP-type El Niño, the significantly reduced forecast error (at the 0.1 level) could be seen in the downscaling model and CFSv2.

Authors: Manayan Regan C. , Haser Erin K. , Shah Ameer T. , Crawford Kayva L. , Vecchiotti Mark A. , Scott Andrew R.
Published: July 2020

Objectives:

Prophylactic flexible bronchoscopy immediately following open airway reconstruction allows for directed clearance of the distal airways, potentially reducing the rate of certain postoperative respiratory complications. In this investigation, we sought to determine if prophylactic flexible bronchoscopy at the conclusion of pediatric open airway reconstruction has any benefit over blind flexible suctioning of the trachea.

Methods:

A retrospective, single-center study at an urban tertiary care hospital was completed. From January 2010 to April 2013, patients underwent open airway reconstruction, immediately followed by blind flexible suctioning of the trachea for distal airway clearance. From May 2013 through December 2016, sequential patients underwent prophylactic flexible bronchoscopy immediately following airway reconstruction.

Results:

A total of 29 patients (age: 3.6 months-6.2 years) met inclusion criteria. Sixteen sequential patients underwent simple blind flexible suctioning and 13 sequential patients underwent directed, prophylactic flexible bronchoscopy. Demographics and comorbidities between the groups were equivalent other than slightly older age in the prophylactic bronchoscopy group. All clinical outcomes analyzed were equivalent other than faster time to room air ( P < .002) and a decrease in the number of chest physical therapy sessions ( P < .02) in a subset of patients who did not undergo prophylactic bronchoscopy.

Conclusion:

This investigation suggests that the use of prophylactic flexible bronchoscopy immediately following open airway reconstruction may not be superior to blind flexible suctioning of the trachea in limiting postoperative pulmonary complications. Further studies of greater power are needed to better elucidate any small differences that may exist between these two interventions.

“How many units to take in a sample to choose” is a classical problem in sample surveys addressed by numerous predecessors. Chebyshev’s inequality provides a tool in simple random sampling as may as well be extended to varying probability sampling. Two approaches are presented. But critically, in indirect surveys to cover sensitive issues, problems seem to be insurmountable, as illustrated.

Care coordination (CC) facilitates access to resources/services for children/youth with special health care needs (CYSHCN). We conducted a cross-sectional analysis of the 2009-2010 National Survey of CSHCN to examine socioeconomic factors related to report of receiving adequate CC services for CYSHCN. Descriptive statistics were used to describe sociodemographic characteristics of respondents and examine socioeconomic factors. Receiving adequate CC varied by socioeconomic variables including income (100% to 199% federal poverty line [FPL]; aOR [adjusted odds ratio] = 0.848; 95% CI [confidence interval] = 0.722-0.997; P < .05), insurance (uninsured; aOR = 0.446; 95% CI = 0.326-0.609; P < .0001), and marital status (never married; aOR = 0.79; 95% CI = 0.64-0.97; P < .05). More families reporting adequate CC had private insurance, non-Hispanic white ethnicity, income >400% federal poverty level, and 2-parent households. Findings suggest unmet needs in terms of adequate access or knowledge leading to insufficient provision of CC for families with the greatest needs. Further analysis identifying specific deficits and implementing strategies to address these disparities is warranted.

This study sought to understand caregiver needs of children with tracheostomies (CWT) living at home and inform development of standardized tracheostomy simulation training curricula. Long-term goals are decreasing hospital readmissions following tracheostomy placement and improving family experiences while implementing a medical home model. We recruited caregivers of CWT and conducted semistructured interviews, subsequently recorded, transcribed, and analyzed for emerging themes using NVivo. Demographic data were collected via quantitative surveys. Twenty-seven caregivers participated. Emerging themes included the following: (1) caregivers felt overwhelmed, sad, frightened when learning need for tracheostomy; (2) training described as adequate, but individualized training desired; (3) families felt prepared to go home, but transition was difficult; (4) home nursing care fraught with difficulty and yet essential for families of CWT. Families of CWT have specific needs related to discharge training, resources, support, and home nursing. Provider understanding of caregiver needs is essential for child well-being, patient-/family-centered care, and may improve health outcomes.
Redefining norms, exploring new avenues: Negotiations of women informal workers in Delhi
Authors: Khurana Sakshi
Published: July 2020

The changing nature of production activities in developing countries has brought into focus the contribution of large numbers of women who get pulled into the labor force either by choice or by compulsion. Women in the latter category often find themselves engaged in informal employment, in work that is inconsistent and low-paid, carried out under suboptimal working conditions. Their ability to improve their conditions of work and life is constrained not just by capitalist structures and the organization of production relations, but also by social structures of norms and cultural practices. The analysis in this article, based on ethnographic research among women engaged in the garment and construction industries in Delhi provides insights into the strategies that some women workers, in the two sectors that also largely comprised women belonging two different religious communities, adopt to contest precarious working conditions and patriarchal norms, and transition into more autonomous positions. This article asks that given the constraints particular to the garment and construction sectors, why and how do some women resist against structures of gender oppression? How do the differences or similarities in the socio-cultural norms of the two communities constrain and at times, also enable women’s choices and actions? This article brings forth the factors that lead women to resist against structures of gender oppression, challenge inequalities inherent in the organization of work, and the new meanings that they may assign to their own negotiations and interpretations of norms.
COVID-19 and the Mental Health of People From Refugee Backgrounds
Authors: Rees Susan , Fisher Jane
Published: July 2020

Approximately 1 in 10 of the current 26 million people who are refugees reside in high-income countries. They have commonly experienced trauma related to violence, insecurity, persecution and shortage of food and medicine. Our research suggests that COVID-19 and its health and social sequalae may be triggering past traumatic reactions, exacerbating mental health problems and undermining functioning. The purpose of this article is to promptly communicate these anecdotal findings to general health practitioners to ensure informed and sensitive health care delivery to this vulnerable population.
Cocreation Experience in Peer-to-Peer Accommodations: Conceptualization and Scale Development
Authors: Zhang Pei , Meng Fang , So Kevin Kam Fung
Published: July 2020

Most value cocreation measurement scales have focused on physical cocreation behavior rather than the cocreation experience. This study aims to conceptualize the construct of cocreation experience and develop a corresponding measurement scale in peer-to-peer accommodations using a sequential mixed-methods approach. The multistage scale development procedure generated a measurement containing six reflective dimensions: authenticity, autonomy, control, learning, personalization, and connection. This study contributes to the literature by conceptualizing and operationalizing the construct of the cocreation experience in peer-to-peer accommodations. Findings provide insight into customers’ shared experiences and enable tourism and hospitality practitioners to improve the customer experience.
Celebrating the Great Union through Smart Digital Solutions: Lessons from Alba Iulia, Romania

Published: July 2020

After World War I, Transylvania became part of Romania in 1918 through what is called the Great Union. After 100 years, Alba Iulia authorities celebrated the Unification Centennial in a symbolic way by testing and implementing 100 smart digital projects. The research question is asked, Is Alba Iulia a true smart city? Methodologically, we centralized the urban regeneration and sustainable development projects, plotting them on a map using geographic information system ArcGIS 16.2 software. The results were interpreted using the arch over time method and emphasized the sustainable development tendencies of the Union City a century later. Its policies and projects make Alba Iulia a model for emergent development despite some unsolved gaps such as social inclusion of marginal communities or real urban smart functionality. Conclusively, the current poor implementation of smart applications certifies Alba Iulia’s digital city status, not as one of smart city.
A laboratory approach to predict the water-based drill-in fluid damage on a shale formation

Published: July 2020

Shale gas production after drill-in, completion, and hydraulic fracturing is strongly affected by formation damage. In order to determine the damage mechanisms for nonmarine shale reservoir, a series of assessments of sensitivity damage, water block damage, water-based drill-in fluids damage, and water damage to gas diffusion on 20 shale samples obtained from Chang 7 Formation were conducted and analyzed. Results indicate that, in the Chang 7 Formation shale, there is extremely strong stress sensitivity and moderately weak water sensitivity damage. Although the liquid phase invasion depth is shallow and the water block damage is limited, the liquid phase and solid particles would enter the microfractures in the reservoir.The P-1 water-based drill-in fluid is compatible with the Chang 7 Formation shale reservoir which can meet the requirement of Chang 7 Formation shale damage controlling, the effect of water-based drill-in fluid on wellbore stability should be paid more attention. The diffusion coefficient of the shale decreases with the presence of water.A systematic damage evaluation method of working fluid considering the multi-mechanism and multi-scale mass transfer process of shale gas is needed to establish.

Background:

The therapeutic reference range for venlafaxine in antidepressant treatment has been defined as 100 to 400 ng/mL. However, in an everyday setting active moiety concentrations above the therapeutic reference range were often reported.

Aim:

The aim of this study was to re-evaluate the therapeutic reference range of venlafaxine.

Methods:

In-patients (⩽60 years) with major depressive episodes receiving antidepressant monotherapy with venlafaxine during routine clinical treatment were included in this observational study. Depressive symptom severity was evaluated on a weekly basis using the Hamilton Depression Rating Scale (HAMD-21), and therapeutic drug monitoring analyses were performed. Resting electrocardiograms were analyzed in week 3, week 5 and week 7 of study participation.

Results:

Clinical improvement from baseline to week 4 was significantly associated with increasing serum concentrations of the active moiety of venlafaxine ( N = 23, Pearson correlation, p = 0.009), but not with the dose of venlafaxine. Patients achieving remission showed significantly higher serum concentrations than patients achieving response/non-response (Kruskal–Wallis test, p = 0.019). Moreover, in patients with serum concentrations above 400 ng/mL time to remission and time to response was significantly shorter than in patients with concentrations below 400 ng/mL (Mantel–COX test, p = 0.001; p = 0.010). QTc time was below the upper limit of a normal QTc time (450 ms) for all patients.

Conclusion:

The serum concentration of the active moiety and not the dose determined the effect of venlafaxine. Shorter remission times without ECG alterations in patients with serum concentrations above the therapeutic reference range suggest a re-evaluation of the therapeutic reference range for venlafaxine in larger studies.

In this study, we applied on-resonance variable delay multiple pulse (onVDMP) MRI to study D-glucose uptake in a mouse model of Alzheimer’s disease (AD) tauopathy and demonstrated its feasibility in discriminating AD mice from wild-type mice. The D-glucose uptake in the cortex of AD mice (1.70 ± 1.33%) was significantly reduced compared to that of wild-type mice (5.42 ± 0.70%, p = 0.0051). Also, a slower D-glucose uptake rate was found in the cerebrospinal fluid (CSF) of AD mice (0.08 ± 0.01 min−1) compared to their wild-type counterpart (0.56 ± 0.1 min−1, p < 0.001), which suggests the presence of an impaired glucose transporter on both blood–brain and blood–CSF barriers of these AD mice. Clearance of D-glucose was observed in the CSF of wild-type mice but not AD mice, which suggests dysfunction of the glymphatic system in the AD mice. The results in this study indicate that onVDMP MRI could be a cost-effective and widely available method for simultaneously evaluating glucose transporter and glymphatic function of AD. This study also suggests that tau protein affects the D-glucose uptake and glymphatic impairment in AD at a time point preceding neurofibrillary tangle pathology.
