Authors: Hashimoto Shoji , Imamura Naohiro , Kaneko Shinji , Komatsu Masabumi , Matsuura Toshiya , Nishina Kazuya , Ohashi Shinta
Published: January 2020

Most of the area contaminated by the Fukushima Daiichi Nuclear Power Plant accident is covered by forest. In this paper, we updated model predictions of temporal changes in the 137Cs dynamics using the latest observation data and newly provided maps of the predicted 137Cs activity concentration for wood, which is the most commercially important part of the tree body. Overall, the previous prediction and latest observation data were in very good agreement. However, further validation revealed that the migration from the soil surface organic layer to the mineral soil was overestimated for evergreen needleleaf forests. The new prediction of the 137Cs inventory showed that although the 137Cs distribution within forests differed among forest types in the first 5 years, the difference diminished in the later phase. Besides, the prediction of the wood 137Cs activity concentrations reproduced the different trends of the 137Cs activity concentrations for cedar, oak, and pine trees. Our simulation suggests that the changes of the wood 137Cs activity concentration over time will slow down after 5–10 years. Although the model uncertainty should be considered and monitoring and model updating must continue, the study provides helpful information on the 137Cs dynamics within forest ecosystems and the changes in wood contamination.

Published: January 2020

Despite the growing interest on the effect of the social context on pain, whether and how different facets of interpersonal interactions modulate pain are still unclear. We tested whether personal (i.e., convenient for the self), moral (i.e., equitability of the transaction) or social (i.e., positive vs. negative feedback from others) valence of an interpersonal interaction differentially affects pain and the perceived fairness. Thirty-two healthy participants played the role of Receivers in a Dictator Game, where a player, the Dictator, determined how to divide a payoff between her/himself and the other player, the Receiver. We manipulated the payoff (pain vs. money), the personal valence (favorable vs. unfavorable offer to participants), the moral valence of the offer (from very iniquitous to equitable), and social valence of the Dictator (social acceptance vs. rejection). Moral and personal valence differentially modulated pain. Lower pain was elicited by iniquity, but also by favorable offers. Moreover, unfavorable offers in the economic game were rated as more unfair, whereas only very iniquitous offers elicited such ratings in the pain game, suggesting that participants valued when Dictators endured extra pain for their benefit. Together, we show that the valence of a social interaction at different levels can independently modulate pain and fairness perception.
Maternal high fat diet consumption reduces liver alpha7 nicotinic cholinergic receptor expression and impairs insulin signalling in the offspring

The activation of nicotinic acetylcholine receptor α7 subunit (α7nAChR) has been associated to anti-inflammatory response in macrophages. High-fat diet (HFD) consumption during pregnancy and lactation impairs the cholinergic anti-inflammatory pathway in liver and white adipose tissue of offspring. In order to evaluate the relationship between damage in the cholinergic anti-inflammatory pathway and insulin resistance (IR) development, the liver of offspring of obese dams was investigated. Additionally, the capacity of α7nAChR activation to reduce IR induced by saturated fatty acid was investigated in hepatoma cell line. Initially, female mice were subjected to either standard chow (SC) or HFD during pregnancy and lactation period. After weaning, only male offspring from HFD dams (HFD-O) and SC dams (SC-O) were fed with the SC diet. Hepatic α7nAChR expression was downregulated, and hepatic TNF-α, IL-1β, and pIKK level, but not pJNK, were elevated in the HFD-O compared to SC-O mice. Besides, hepatic expression of TNF-α in response to lipopolysaccharide (LPS) was higher in HFD-O than SC-O mice. Insulin-stimulated phosphorylation of the AKT was lower in HFD-O compared to SC-O. Additionally, insulin-stimulated phosphorylation of the AKT in KOα7Alb-Cre mice fed HFD was lower than WT mice fed HFD. In hepatoma cell line, palmitate increased IL-6 and TNF-α expressions and pJNK level. These effects were accompanied by reduced capacity of insulin to stimulate AKT phosphorylation. PNU or nicotine reduced cytokine expression and JNK activation, but improved insulin resistance induced by palmitate. Our results suggest that maternal obesity impairs hepatic α7nAChR expression and AKT phosphorylation in the offspring. In vitro studies suggest that α7nAChR activation has potential to reduce deleterious effect of saturated fatty acids on insulin signalling.
Confinement Effect on Porosity and Permeability of Shales

Published: January 2020

Porosity and permeability are the key factors in assessing the hydrocarbon productivity of unconventional (shale) reservoirs, which are complex in nature due to their heterogeneous mineralogy and poorly connected nano- and micro-pore systems. Experimental efforts to measure these petrophysical properties posse many limitations, because they often take weeks to complete and are difficult to reproduce. Alternatively, numerical simulations can be conducted in digital rock 3D models reconstructed from image datasets acquired via e.g., nanoscale-resolution focused ion beam–scanning electron microscopy (FIB-SEM) nano-tomography. In this study, impact of reservoir confinement (stress) on porosity and permeability of shales was investigated using two digital rock 3D models, which represented nanoporous organic/mineral microstructure of the Marcellus Shale. Five stress scenarios were simulated for different depths (2,000–6,000 feet) within the production interval of a typical oil/gas reservoir within the Marcellus Shale play. Porosity and permeability of the pre- and post-compression digital rock 3D models were calculated and compared. A minimal effect of stress on porosity and permeability was observed in both 3D models. These results have direct implications in determining the oil-/gas-in-place and assessing the production potential of a shale reservoir under various stress conditions.

Published: January 2020

The objective was to examine 10-year changes in dietary carbon footprint relative to individual characteristics and food intake in the unique longitudinal Västerbotten Intervention Programme, Sweden. Here, 14 591 women and 13 347 men had been followed over time. Food intake was assessed via multiple two study visits 1996–2016, using a 64-item food frequency questionnaire. Greenhouse gas emissions (GHGE) related to food intake, expressed as kg carbon dioxide equivalents/1000 kcal and day, were estimated. Participants were classified into GHGE quintiles within sex and 10-year age group strata at both visits. Women and men changing from lowest to highest GHGE quintile exhibited highest body mass index within their quintiles at first visit, and the largest increase in intake of meat, minced meat, chicken, fish and butter and the largest decrease in intake of potatoes, rice and pasta. Women and men changing from highest to lowest GHGE quintile exhibited basically lowest rates of university degree and marriage and highest rates of smoking within their quintiles at first visit. Among these, both sexes reported the largest decrease in intake of meat, minced meat and milk, and the largest increase in intake of snacks and, for women, sweets. More research is needed on how to motivate dietary modifications to reduce climate impact and support public health.

Published: January 2020

Intravitreal (IVT) injection has become the standard route for drug administration in retinal diseases. However, the ability to measure biodistribution of ocular therapeutics in large species remains limited, due to the invasive nature of some techniques or their lack of spatial information. The aim of this study was to develop in cynomolgus monkeys a non-invasive fluorescence imaging technology that enables tracking of IVT-dosed drugs and could be easily translated into humans. Here, we show a proof-of-concept for labeled ranibizumab with observed half-lives of 3.34 and 4.52 days at the retina and in the vitreous, respectively. We further investigate a long acting anti-VEGF antibody, which remains as an agglomerate with some material leaking out until the end of the study at Day 35. Overall, we were able to visualize and measure differences in the in vivo behavior between short and long-acting antibodies, demonstrating the power of the technology for ocular pharmacokinetics.

Two‐UAV trajectory planning for cooperative target locating based on airborne visual tracking platform
Authors: Xu Cheng , Yin Chanjuan , Han Wei , Wang Dongzhen
Published: January 2020

Two‐unmanned‐aerial‐vehicle (UAV) cooperative target locating based on airborne visual tracking platform is a common UAV reconnaissance mode. In the process of two‐UAV cooperative target locating, the performance of target locating is highly dependent on UAV trajectory. In this Letter, a trajectory planning method for two‐UAV cooperative target locating is presented. Using the line‐of‐sight (LOS) targeting property of the airborne visual tracking platform, in combination with the azimuth angle and elevation angle of the measured LOS, a locating error model is established, which can reflect the correlation between the target locating error and LOS angle error. Then an objective function based on minimising the target locating error is built, which is used as an index of two‐UAV trajectory planning. This method can be applied in two‐UAV trajectory planning for cooperative target locating and the simulated results confirm that it works effectively.
Vertical bipolar junction transistor triggered silicon‐controlled rectifier for nanoscale ESD engineering
Authors: Du Feibo , Hou Fei , Song Wenqiang , Xu YiChen , Liu Jizhi , Liu Zhiwei , Liou Juin J.
Published: January 2020

In this Letter, a novel vertical bipolar junction transistor (BJT) triggered silicon‐controlled rectifier (VBTSCR) is proposed for advanced nanoscale electrostatic discharge (ESD) protection applications. With the help of a vertical NPN transistor in floating base configuration, the new silicon‐controlled rectifier (SCR) structure achieves lower trigger voltage and better clamping capacity than the prior enhanced modified lateral SCR (EMLSCR) under the same layout footprint. The ESD characteristics are measured using the transmission line pulsing tester. Compared with that of EMLSCR, the trigger voltage of VBTSCR drops by 1 V, and the effective ESD robustness of VBTSCR has been doubled significantly. Based on these advantages, the proposed VBTSCR can provide ESD protection for the advanced 1.8/2.5 V input/output circuits more efficiently.
Variable coefficient fractional‐order PID controller and its application to a SEPIC device
Authors: Chen Liping , Chen Gang , Wu Ranchao , Lopes António M. , Tenreiro Machado José António , Niu Haihong
Published: January 2020

The fractional‐order proportional–integral–derivative (FOPID) controller has two more parameters than the integer‐order proportional–integral–derivative (PID). Such characteristic makes the controller design more flexible and leads to superior performance. This study proposes a variable coefficient FOPID (VCFOPID) with optimal single step parameters, combining discrete synthesis and variable control parameters. The new algorithm is compared with previous FOPID discrete methods via several examples. Since the energy losses of the single‐ended primary‐inductor converter (SEPIC) cannot be ignored, the standard models are insufficient and a new model is derived using quantum‐behaved particle swarm optimisation. The VCFOPID is applied to the SEPIC and both the effectiveness of the controller and the model are verified experimentally.

In this study, a simple hyperplane design method based on the discrete‐time Riccati equation is proposed, and the inter‐relations are investigated for the basic requirement on sliding surface selection, the assumption of stabilisability, the Riccati inequality and the standard Riccati equation. A state and disturbance observer is embedded in discrete‐time sliding mode control (DSMC) to achieve its applicability when only partial system states can be measured. In order to improve the performance of the system in control updating times, a novel event‐triggered DSMC with a state and disturbance observer is proposed. It is shown that the proposed method achieves a quasi sliding mode with a small boundary layer. Simulation examples are presented to show the effectiveness and advantages of the proposed design schemes.
Tracking consensus for stochastic hybrid multi‐agent systems with partly unknown transition rates via sliding mode control
Authors: Mu Xiaowu , Wu Xihui
Published: January 2020

The tracking consensus problem for stochastic Markovian multi‐agent systems (MASs) with mismatched uncertainty is investigated in this study. A restrictive assumption for stochastic systems in existing results is removed in this study. Under the directed interacted topology, the sliding mode control method is utilised to achieve leader‐following consensus for general linear MASs in the sense of mean square. Integral sliding mode surfaces are employed to tackle the mismatched uncertainties. Then, with the transition rates of Markov process being completely known or partly unknown, two kinds of distributed sliding mode protocols are given, respectively. Based on the sliding mode control theory, algebraic graph theory and stochastic differential equation theory, mean square stability of sliding mode dynamics are ensured by LMIs and reachability of sliding mode surfaces almost surely from the initial time are obtained. Finally, simulations are given to illustrate the effectiveness of the results.

Published: January 2020

In this study, trajectory tracking control is investigated based on a double closed‐loop strategy for a wheeled mobile robot with an omnidirectional wheel on uneven ground. The omnidirectional wheel is used to make the wheeled mobile robot turn smoothly, however, external disturbances are caused when the wheeled mobile robot goes straight. Moreover, the external disturbances also come from uneven ground for the wheeled mobile robot. An extended state observer with a time‐varying gain is designed to estimate the external disturbances in an inner loop of the double closed‐loop strategy. Then a torque control law for integral sliding mode control is given to track desired velocities. In an outer loop, a kinematic controller is designed to generate the desired velocities. Experimental results are given to show the effectiveness and superiority of the double closed‐loop strategy for the wheeled mobile robot.
Delay‐dependent stability of a class of stochastic delay systems driven by G‐Brownian motion
Authors: Yao Shenghao , Zong Xiaofeng
Published: January 2020

This study discusses delay‐dependent stability of a class of stochastic delay systems driven by G‐Brownian motion in the sublinear expectation space. With the help of the degenerate Lyapunov functional, the mean square exponential stability and quasi‐sure exponential stability criteria for stochastic delay systems driven by G‐Brownian motion are established and an explicit upper bound of time delay is derived. In particular, for the delay‐free case, the corresponding sufficient conditions are also obtained. Here, the stability conditions are directly related to the coefficients of the stochastic delay systems and are different from the existing stability conditions which are presented in terms of the G‐Lyapunov function. Some examples are introduced to illustrate the delay‐dependent stability criteria.

Published: January 2020

This article proposes an intelligent charge scheduling strategy for electric vehicles (EVs) in residential areas based on real‐time guide (RTG) tariffs which are set dynamically according to the load information. The architecture of the system realises the interconnection of information on vehicles and distribution networks. The authors first establish a mathematical model, the objective of which is to accomplish the charging task in an economical way within a given deadline. The authors then introduce dual theory for a distributed computing to the model. EVs obtain an optimised charging plan using the intelligent charge scheduling system, which ensures the safe operation of the distribution transformer. Finally, taking the load curve of a residential area as an example, the Monte–Carlo simulation method is utilised to calculate the charging needs of customers based on actual customer charging behaviour. The distribution transformer load curve and average charge per vehicle are simulated under both uncoordinated and coordinated charging conditions, and the simulation results indicate that the scheduling strategy can reduce the required charge and achieve a smoother load curve, and is suitable for vehicle online scheduling.

Context.High-mass X-ray binaries (HMXBs) are exceptional astrophysical laboratories that offer a rare glimpse into the physical processes that govern accretion on compact objects, massive-star winds, and stellar evolution. In a subset of the HMXBs, the compact objects accrete matter solely from winds of massive donor stars. These so-called wind-fed HMXBs are divided in persistent (classical) HMXBs and supergiant fast X-ray transients (SFXTs) according to their X-ray properties. While it has been suggested that this dichotomy depends on the characteristics of stellar winds, they have been poorly studied.

Aims.With this investigation, we aim to remedy this situation by systematically analyzing donor stars of wind-fed HMXBs that are observable in the UV, concentrating on those with neutron star (NS) companions.

Methods.We obtainedSwiftX-ray data, HST UV spectra, and additional optical spectra for all our targets. The spectral analysis of our program stars was carried out with the Potsdam Wolf–Rayet model atmosphere code.

Results.Our multi-wavelength approach allows us to provide stellar and wind parameters for six donor stars (four wind-fed systems and two OBe X-ray binaries). The wind properties are in line with the predictions of the line-driven wind theory. Based on the abundances, three of the donor stars are in an advanced evolutionary stage, while for some of the stars, the abundance pattern indicates that processed material might have been accreted. When passing by the NS in its tight orbit, the donor star wind has not yet reached its terminal velocity but it is still significantly slower; its speed is comparable with the orbital velocity of the NS companion. There are no systematic differences between the two types of wind-fed HMXBs (persistent versus transients) with respect to the donor stars. For the SFXTs in our sample, the orbital eccentricity is decisive for their transient X-ray nature. The dichotomy of wind-fed HMXBs studied in this work is primarily a result of the orbital configuration, while in general it is likely that it reflects a complex interplay between the donor-star parameters, the orbital configuration, and the NS properties. Based on the orbital parameters and the further evolution of the donor stars, the investigated HMXBs will presumably form Thorne–Żytkow objects in the future.

Background and study aims Iatrogenic endoscopic ultrasound (EUS) perforations are life-threatening adverse event and to date, surgery has been the main treatment for them. The aim of this study was to assess feasibility and safety of conservative treatment with over-the-scope clips (OTSC).

Patients and methods We performed a retrospective study, including iatrogenic EUS duodenal perforation with conservative endoscopic management from 2011 to August 2018. Patients who initial had surgical management were excluded.

Results In 8504 EUS procedure occurred, 13 perforations occurred (0.15 %). Eleven patients were included in the study, all women. Mean patient age was 75 years (range 68 – 88). Eighth of 11 perforations (72.7 %) were due to a radial probe and three of 11 (27.3 %) were due to a curvilinear probe. Eleven procedures (100 %) were performed as diagnostic. Defect size ranged from 10 to 15 mm. All procedures were successful. Three of eleven patients (27 %) had a stay in intensive care unit for less than 72 hours and length of total hospital stay ranged from 3 to 22 days.

Conclusion Conservative endoscopic treatment of Iatrogenic EUS perforation, with OTSC is feasible, efficient and safe.

Anamnese Ein 53-jähriger Patient stellte sich mit massivem Pruritus bei Ganzkörperexanthem, generalisierten Muskelschmerzen und Belastungsdyspnoe NYHA II vor.

Untersuchungen und Diagnose Durch weiterführende hämatologische Untersuchungen wurde die Diagnose einer myeloischen und lymphatischen Neoplasie mit Eosinophilie (MLN-EO) und Nachweis eines FIPL1L1-PDGFRA-Fusionsgens gestellt. Im Rahmen der kardiologischen Diagnostik erfolgte eine echokardiografische Untersuchung mit Nachweis eines Thrombus im rechten Ventrikel. In der Magnetresonanztomografie (MRT) zeigte sich der intrakavitäre Thrombus vom Apex bis zum rechtsventrikulären Ausflusstrakt reichend.

Therapie und Verlauf Eine orale Antikoagulation mit Phenprocoumon und eine zielgerichtete Therapie mit Imatinib wurden initiiert. Hierunter konnte in den 11- und 23-monatigen Verlaufskontrollen mittels Magnetresonanztomografie der Thrombus nachweislich aufgelöst werden. Der weitere Verlauf gestaltete sich komplikationslos.

Folgerung Eine Löffler-Endokarditis mit begleitendem Ventrikelthrombus auf dem Boden einer myeloischen und lymphatischen Neoplasie mit Eosinophilie kann durch orale Antikoagulation und Therapie mit Imatinib erfolgreich behandelt werden.

Published: January 2020

Background and study aims Mucosal healing (MH) is associated with clinical outcome in ulcerative colitis (UC) patients. In most clinical trials, a Mayo endoscopic subscore (MES) of 0 or 1 is defined as MH. However, several recent studies have reported that clinical outcome is different between UC patients with MES 0 and those with MES 1. In addition, the MES is subjective and may differ among endoscopists. Therefore, a repeatable and objective scoring system is required to distinguish MES 0 from MES 1, even in clinically quiescent UC. Here, we assessed the usefulness of new image-enhancing endoscopic technology, the i-scan TE-c, to quantitatively evaluate colonic inflammation in patients with quiescent UC.

Methods We retrospectively reviewed the data from 52 UC patients in clinical remission who had undergone routine colonoscopy with standard white light. The white-light images were reassessed using the new system, and the degree of colonic mucosal inflammation was quantified according to the MAGIC (Mucosal Analysis of Inflammatory Gravity by i-scan TE-c Image) score. We used the i-scan TE-c system to investigate the association among the MAGIC score, MES, and histologic activity (Geboes score).

Results The MAGIC score was significantly higher in the MES 1 group than in the MES 0 group (P = 0.0034). The MAGIC score significantly correlated with the Geboes score (P = 0.015).

Conclusions Our novel image-enhancing endoscopic system was useful for objective and quantitative evaluation of MH in patients with quiescent UC. Further clinical studies using this imaging system are required to confirm its clinical benefit for the management of UC patients.
