How modality processing differences affect cross‐modal nonspatial repetition inhibition
Authors: Wang Aijun , Wu Xiaogang , Tang Xiaoyu , Zhang Ming 
Published: January 2020

AbstractAlthough previous studies have demonstrated that identity‐based repetition inhibition could occur across modalities, whether the modality processing difference or attentional set caused differences between the unimodal and cross‐modal conditions was unknown. To investigate this question in both visual–auditory and auditory–visual patterns, the present study adopted a cross‐modal “prime‐neutral cue‐target” priming paradigm, in which a neutral event was presented between the prime and the target. The relationships of the identities and modalities between the prime and the target were manipulated such that their modalities and identities could either be the same or different. Our results showed that (a) identity‐based repetition inhibition occurred under both unimodal and cross‐modal conditions, (b) response times to auditory targets were slower than those to visual targets, and (c) identity‐based repetition inhibition was larger while discriminating repeated auditory targets than visual targets regardless of whether the prime was visual or auditory. These results suggested that nonspatial repetition inhibition can occur across modalities and that it was not in general larger or smaller than unimodal repetition inhibition, as this difference was due to modality processing differences.

Published: January 2020

AbstractPurposeBayesian hierarchical models (BHMs) have been used to identify adverse drug reactions, allowing information sharing amongst adverse reactions and drugs expected to have similar properties. This study evaluated the use of BHMs in the routine signal detection analyses of potential first‐trimester teratogens, where these models have not previously been applied.MethodsData on 15 058 malformed foetuses exposed to first trimester medications (1995‐2011) from 13 European congenital anomaly (CA) registries were analysed. The proportion of each CA in women taking a specific medication was compared with the proportion of that CA in all other women in the dataset (55 CAs × 523 medications). BHMs were grouped by either medications or CAs or by both simultaneously, and the results compared with analysing each medication‐CA combination separately and adjusting for multiplicity using a double false discovery rate (FDR) procedure. The proportions of “high‐risk” medications (medications which have been shown to carry a moderate to high risk of foetal malformations) identified as potential signals were compared, as well as the total number of potential signals requiring follow up (the effective workload).ResultsBHMs identified more high‐risk medications than the double FDR method, but the effective workload was larger. A BHM grouping both medications and CAs, for example, identified 23% of high‐risk medications compared with 14% by the double FDR; however, there was an increase from 16 to 71 potential signals requiring follow up.ConclusionFor comparable effective workloads, BHMs did not outperform the double FDR, which is comparatively straightforward to implement and is therefore recommended for continued use in teratogenic signal detection analyses.

AbstractThis review summarizes primary studies on teachers’ preferences and perceptions of the psychological report. A systematic search identified 19 studies meeting the inclusion criteria. These studies were evaluated in terms of (a) psychological report section focus, (b) methodology, (c) research results, (d) discussion, and (e) recommendations. Across the 19 studies, 1,309 general and special education teachers indicated and rated their preferences and perceptions of the psychological report. In terms of the entire psychological report and especially the report recommendations, teachers preferred longer, descriptive, and more detailed reports. Teachers preferred reports that provided enough detail to aid in individualized education planning and recommendation and intervention implementation. Teachers also preferred reports written in integrated theme‐based formats as opposed to test‐by‐test formats. Teachers rated the level of detail and degree of psychological jargon used in reports as currently unsatisfactory. This review summarizes teacher preferences and identifies report features that aid in report comprehension and also provides a research basis from which to inform training and practice in psychological report writing.

ABSTRACTThe interfacial grafting copolymerization and the compatibility between poly(lactic acid) (PLA) and ethylene‐vinyl acetate‐glycidyl methacrylate elastomer (EVM‐GMA) are adjusted by varying the blending temperatures. High temperature is favored to the grafting reaction between epoxy groups of the EVM‐GMA and terminal groups of the PLA, resulting in better compatibility between the two components. Taking PLA/EVM‐GMA (80/20) blend as an example, an increase in blending temperature from 175 to 230 °C led to a 42.8% reduction in EVM‐GMA particle size, and consequently 137.8% and 52.6% increases in elongation at break (Eb) and notched impact strength (NIS), respectively. In comparison, the Eb and NIS of PLA/EVM blends without any interfacial reaction deteriorated dramatically due to thermal degradation of the PLA at high(er) temperatures. Furthermore, the PLA/EVM‐GMA blend prepared at 230 °C possesses both excellent toughness (Eb > 60%, NIS > 60 kJ m−2) and high heat deflection temperature (>90 °C) after annealing at 100 °C. This work provides a new approach in designing high‐performance biobased materials which may broaden the application range of PLA in engineering areas. © 2020 Wiley Periodicals, Inc. J. Polym.

AbstractObjectiveThe diagnosis of foreign body aspiration (FBA) is challenging. In a previous study, we developed a computerized scoring system (CSS) to support decision‐making. In the present study, we aimed to validate it on a further cohort.Study DesignIn this observational study, 100 children referred to the emergency department of a tertiary pediatric hospital for suspected FBA and treated according to standard protocol, were assigned a probability score using the CSS, between 0 and 1 (0, very low probability; 1, very high). The diagnosis of FBA was based on bronchoscopy, and if discharged without bronchoscopy, determined via telephone questionnaire, 4 to 6 months after discharge, supplemented by clinical re‐evaluation and bronchoscopy, if respiratory symptoms persisted.ResultsThirty‐five out of 100 children (35%) underwent bronchoscopy with 12 of 35 (34%) positive for FBA. Sixty‐five patients were discharged without bronchoscopy and completed a telephone questionnaire. Seven patients required clinical re‐evaluation for persistent respiratory symptoms, in two out of them, additional bronchoscopies were performed and were negative. The CSS median probability score was 0.94 in patients with FBA, as compared to 0.73 in patients without FBA (P = .007). The CSS area under the receiver operating curve was 0.74. At a probability score threshold of 0.6, the sensitivity and specificity were 100% and 41%, respectively.ConclusionThe present validation study suggests a high sensitivity of the CSS for the identification of FBA in children. We suggest that it might aid decision‐making with regard to the need for bronchoscopy in children presenting to the emergency room.

Abstract2D nuclear magnetic resonance (NMR) is essential in molecular structure determination. The nitrogen vacancy (NV) center in diamond is proposed and developed as an outstanding quantum sensor to realize NMR in nanoscale. In this work, a scheme for 2D nanoscale NMR spectroscopy is developed based on quantum controls on an NV center. A proof‐of‐principle experiment on a target of two coupled nuclear spins in diamond is carried out. A correlation spectroscopy (COSY) like sequence is used to acquire the data on time domain, which is then converted to frequency domain with the fast Fourier transform. With the 2D NMR spectrum, the structure and location of the set of nuclear spin are resolved. This work marks a fundamental step toward resolving the structure of a single molecule.

AbstractAerial cinematography is revolutionizing industries that require live and dynamic camera viewpoints such as entertainment, sports, and security. However, safely piloting a drone while filming a moving target in the presence of obstacles is immensely taxing, often requiring multiple expert human operators. Hence, there is a demand for an autonomous cinematographer that can reason about both geometry and scene context in real‐time. Existing approaches do not address all aspects of this problem; they either require high‐precision motion‐capture systems or global positioning system tags to localize targets, rely on prior maps of the environment, plan for short time horizons, or only follow fixed artistic guidelines specified before the flight. In this study, we address the problem in its entirety and propose a complete system for real‐time aerial cinematography that for the first time combines: (a) vision‐based target estimation; (b) 3D signed‐distance mapping for occlusion estimation; (c) efficient trajectory optimization for long time‐horizon camera motion; and (d) learning‐based artistic shot selection. We extensively evaluate our system both in simulation and in field experiments by filming dynamic targets moving through unstructured environments. Our results indicate that our system can operate reliably in the real world without restrictive assumptions. We also provide in‐depth analysis and discussions for each module, with the hope that our design tradeoffs can generalize to other related applications.

AbstractThe study aims to examine the potential relationship between public health expenditures, logistics performance indices, renewable energy, and ecological sustainability in Association of Southeast Asian Nations member countries. The study used secondary data, which downloaded from the World Bank website and tested for hypotheses using the structural equation modeling. The results show that the use of renewable energy in logistics operations will improve environmental and economic performance to reduce emissions, whereas environmental performance is negatively correlated with public health expenditures, indicating that greater environmental sustainability can improve human health and economic growth. The results also show that increased public health spending and poor environmental performance undermine economic growth in low efficiency and low labor productivity, thus reducing the speed of economic activity. On the other hand, the use of renewable energy in logistics cannot only improve the sustainability of the environment but also create a better national image and provide better export opportunities in environmentally friendly countries to promote sustainable economic growth. The outcomes of this study will help the policy/decision makers to make the proper planning to their investments for achieving sustainable economic growth.

Published: January 2020

AbstractWater being most vital component of life is getting contaminated due to inhuman disposal of toxicants in water bodies. Organic compounds such as dyes, pharmaceuticals/drugs, pesticides etc. are used for various purposes and become life threatening when dumped in water bodies without pre‐treatment. Removal of these toxicants from environment is complicated but highly essential for sustainable development. Various methods have been used for this purpose among which adsorption is the most simple, fast, effective and inexpensive method for the removal of such contaminants. Nanomaterial proved to be one of the best adsorbent due to its unique structural properties which provides large surface area and high adsorption capacity. The factors affecting adsorption along with adsorption mechanism is discussed in detail. Detection of the pollutants is also quite tedious work as pollutants are present in trace quantity. UV‐Visible spectrophotometry is widely used detection technique which is easy to operate, produce accurate results and cheap. The review emphasizes the use of nanomaterial as adsorbents for the removal of various organic pollutants from wastewater using UV‐Visible spectrophotometry.

Published: January 2020

AbstractEthylene glycol (EG) is an important chemical and is widely used in the chemical industry. Hydration of ethylene oxide is a common way to produce EG. We performed density function calculations of propylene oxide (PO) ring‐opening reaction under basic, neutral and acidic conditions. We examined the influence of the solvent and electric field (EF) on the geometry, kinetics and thermodynamics of the ring‐opening. The solvent effect increases/decreases the ring‐opening barriers in the basic/neutral systems and EF exhibits significant influence on barriers and reaction heats in basic condition. All the energetic variation due to solvent and EF can be rationalized with the dipole moments of reactants, transition states, and products.

ABSTRACTObjectivesTo explore the risk of small‐for‐gestational age (SGA) and fetal growth restriction (FGR) and to test the performance of first‐trimester screening for SGA and FGR in women with a false‐positive high or intermediate risk for aneuploidy.MethodsThis was a prospective cohort study of women with a singleton pregnancy attending for a routine first‐trimester scan. The risks of aneuploidy and preterm SGA (defined as birth weight < 10th percentile with delivery before 37 weeks) were determined according to Fetal Medicine Foundation algorithms. In non‐malformed euploid pregnancies, the predictive performance of both the aneuploidy and preterm SGA risks was evaluated for SGA, FGR (defined as birth weight < 3rd centile), preterm SGA and early SGA (delivery before 34 weeks), using receiver‐operating‐characteristics (ROC) curve analysis, in those with a high or intermediate risk of aneuploidy and in the overall population.ResultsA total of 2053 pregnancies were included in the analysis, of which 191 (9.3%) were at high or intermediate risk for aneuploidy (≥ 1/1000) and 304 (14.8%) were at high risk for preterm SGA (≥ 1/100). In total, there were 140 (6.8%) cases of SGA, 61 (3.0%) of FGR, 44 (2.1%) of preterm SGA and 33 (1.6%) of early SGA. Among women with a false‐positive high or intermediate risk for aneuploidy, the rates of SGA, FGR, preterm SGA and early SGA were 13.6% (26/191), 7.9 % (15/191), 6.8% (13/191) and 5.8% (11/191), respectively. Compared with women with a first‐trimester low risk for preterm SGA, regardless of aneuploidy risk, those with a high risk for preterm SGA and a high or intermediate risk for aneuploidy had relative risks for SGA, FGR, preterm SGA and early SGA of 6 (95% CI, 3.9–9), 9.2 (95% CI, 5.1–16.5), 13.4 (95% CI, 6.9–26.1) and 17.6 (95% CI, 8.1–38.2), respectively. The predictive performance for SGA of the preterm SGA algorithm was higher in women at high or intermediate risk for aneuploidy than in the overall population (area under the ROC curve (AUC), 0.8 vs 0.7; P < 0.001). Among women at high or intermediate risk for aneuploidy, the predictive performance of the preterm SGA algorithm was better than that of the aneuploidy algorithm for SGA (AUC, 0.80 vs 0.58; P = 0.003), preterm SGA (AUC, 0.85 vs 0.65; P = 0.013) and early SGA (AUC, 0.86 vs 0.60; P = 0.002).ConclusionIn women with a first‐trimester false‐positive high or intermediate risk of aneuploidy, further screening for SGA allows stratification of the risk for fetal growth disorders.

ABSTRACTObjectivesCoarctation of the aorta (CoA) is associated with left ventricular (LV) dysfunction in neonates and adults. Cardiac structure and function in fetal CoA and cardiac adaptation to early neonatal life have not been described. We aimed to investigate the presence of cardiovascular structural remodeling and dysfunction in fetuses with CoA and their early postnatal cardiac adaptation.MethodsThis was a prospective observational case–control study, conducted between 2011 and 2018 in a single tertiary referral center, of fetuses with CoA and gestational age‐matched normal controls. All fetuses/neonates underwent comprehensive echocardiographic evaluation in the third trimester of pregnancy and after birth. Additionally, myocardial microstructure was assessed in one fetal and one neonatal CoA‐affected heart specimen, using synchrotron radiation‐based X‐ray phase‐contrast microcomputed tomography and histology, respectively.ResultsWe included 30 fetuses with CoA and 60 gestational age‐matched controls. Of these, 20 CoA neonates and 44 controls were also evaluated postnatally. Fetuses with CoA showed significant left‐to‐right volume redistribution, with right ventricular (RV) size and output dominance and significant geometry alterations with an abnormally elongated LV, compared with controls (LV midventricular sphericity index (median (interquartile range; IQR), 2.4 (2.0–2.7) vs 1.8 (1.7–2.0); P < 0.001). Biventricular function was preserved and no ventricular hypertrophy was observed. Synchrotron tomography and histological assessment revealed normal myocyte organization in the fetal and neonatal specimens, respectively. Postnatally, the LV in CoA cases showed prompt remodeling, becoming more globular (LV midventricular sphericity index (mean ± SD), 1.5 ± 0.3 in CoA vs 1.8 ± 0.2 in controls; P < 0.001) with preserved systolic and normalized output, but altered diastolic, parameters compared with controls (LV inflow peak velocity in early diastole (mean ± SD), 97.8 ± 14.5 vs 56.5 ± 12.9 cm/s; LV inflow peak velocity in atrial contraction (median (IQR), 70.5 (60.1–84.9) vs 47.0 (43.0–55.0) cm/s; LV peak myocardial velocity in atrial contraction (mean ± SD), 5.1 ± 2.6 vs 6.3 ± 2.2 cm/s; P < 0.05). The neonatal RV showed increased longitudinal function in the presence of a patent arterial duct.ConclusionsOur results suggest unique fetal cardiac remodeling in CoA, in which the LV stays smaller from the decreased growth stimulus of reduced volume load. Postnatally, the LV is acutely volume‐loaded, resulting in an overall geometry change with higher filling velocities and preserved systolic function. These findings improve our understanding of the evolution of CoA from fetal to neonatal life. Copyright © 2020 ISUOG. Published by John Wiley & Sons Ltd.

AbstractBackgroundProlonged postoperative ileus (PPOI) represents a frequent complication following colorectal surgery, affecting approximately 10–15% of these patients. The objective of this study was to evaluate the perioperative risk factors for PPOI development in colorectal surgery.MethodsThe present systematic review and meta‐analysis was conducted in accordance with the PRISMA Statement. PubMed, EMBASE, SciELO, and LILACS databases were searched, without language or time restrictions, from inception until December 2018. The keywords used were: Ileus, colon, colorectal, sigmoid, rectal, postoperative, postoperatory, surgery, risk, factors. The Newcastle–Ottawa scale and the Jadad scale were used for bias assessment, while the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was used for quality assessment of evidence on outcome levels.ResultsOf the 64 studies included, 42 were evaluated in the meta‐analysis, comprising 29,736 patients (51.84% males; mean age 62 years), of whom 2844 (9.56%) developed PPOI. Significant risk factors for PPOI development were: male sex (OR 1.43; 95% CI 1.25–1.63), age (MD 3.17; 95% CI 1.63–4.71), cardiac comorbidities (OR 1.54; 95% CI 1.19–2.00), previous abdominal surgery (OR 1.44; 95% CI 1.19, 1.75), laparotomy (OR 2.47; 95% CI 1.77–3.44), and ostomy creation (OR 1.44; 95% CI 1.04–1.98). Included studies evidenced a moderate heterogeneity. The quality of evidence was regarded as very low‐moderate according to the GRADE approach.ConclusionsMultiple factors, including demographic characteristics, past medical history, and surgical approach, may increase the risk of developing PPOI in colorectal surgery patients. The awareness of these will allow a more accurate assessment of PPOI risk in order to take measures to decrease its impact on this population.
