Facetime vs. Screentime: Gaze Patterns to Live and Video Social Stimuli in Adolescents with ASD
Authors: Grossman R. B. , Zane E. , Mertens J. , Mitchell T.
Published: September 2019

Atypical eye gaze to social stimuli is one of the most frequently reported and studied social behaviors affected by autism spectrum disorder (ASD). The vast majority of this literature is based on analyses of gaze patterns as participants view social information, such as talking faces, on a computer screen. However, recent results suggest that generalizing gaze behaviors from computer screens to live interactions may not be valid. This study examines between- and within-group differences in gaze behaviors of children with ASD and their neurotypical (NT) peers during a screen-based and a live-interaction task. Results show between-group differences in gaze only for the screen-based, but not the live-interaction task. We also find that gaze behavior of NT children during the screen-based task significantly correlates with their gaze behavior during the live interaction; individuals who direct a higher percentage of gaze to the face in one task also did so in the other task. However, there is no significant relationship between the gaze patterns of children with ASD for those two tasks. These results strongly caution against using gaze of individuals with ASD recorded during screen-based tasks as a proxy for understanding their gaze behavior during live social interactions.

Published: September 2019

Human peripheral nerves hold the potential to regenerate after injuries; however, whether a successful axonal regrowth was achieved can be elucidated only months after injury by assessing function. The axolotl salamander is a regenerative model where nerves always regenerate quickly and fully after all types of injury. Here, de- and regeneration of the axolotl sciatic nerve were investigated in a single and double injury model by label-free multiphoton imaging in comparison to functional recovery. We used coherent anti-Stokes Raman scattering to visualize myelin fragmentation and axonal regeneration. The presence of axons at the lesion site corresponded to onset of functional recovery in both lesion models. In addition, we detected axonal regrowth later in the double injury model in agreement with a higher severity of injury. Moreover, endogenous two-photon excited fluorescence visualized macrophages and revealed a similar timecourse of inflammation in both injury models, which did not correlate with functional recovery. Finally, using the same techniques, axonal structure and status of myelin were visualized in vivo after sciatic nerve injury. Label-free imaging is a new experimental approach that provides mechanistic insights in animal models, with the potential to be used in the future for investigation of regeneration after nerve injuries in humans.
Optimal HIV testing strategies for South Africa: a model-based evaluation of population-level impact and cost-effectiveness
Authors: Johnson Leigh F. , van Rensburg Craig , Govathson Caroline , Meyer-Rath Gesine
Published: September 2019

Although many African countries have achieved high levels of HIV diagnosis, funding constraints have necessitated greater focus on more efficient testing approaches. We compared the impact and cost-effectiveness of several potential new testing strategies in South Africa, and assessed the prospects of achieving the UNAIDS target of 95% of HIV-positive adults diagnosed by 2030. We developed a mathematical model to evaluate the potential impact of home-based testing, mobile testing, assisted partner notification, testing in schools and workplaces, and testing of female sex workers (FSWs), men who have sex with men (MSM), family planning clinic attenders and partners of pregnant women. In the absence of new testing strategies, the diagnosed fraction is expected to increase from 90.6% in 2020 to 93.8% by 2030. Home-based testing combined with self-testing would have the greatest impact, increasing the fraction diagnosed to 96.5% by 2030, and would be highly cost-effective compared to currently funded HIV interventions, with a cost per life year saved (LYS) of $394. Testing in FSWs and assisted partner notification would be cost-saving; the cost per LYS would also be low in the case of testing MSM ($20/LYS) and self-testing by partners of pregnant women ($130/LYS).

Published: September 2019

High-throughput sequencing produces an extraordinary amount of genomic data that is organized into a number of high-dimension datasets. Accordingly, visualization of genomic data has become essential for quality control, exploration, and data interpretation. The Variant Call Format (VCF) is a text file format generated during the variant calling process that contains genomic information and locations of variants in a group of sequenced samples. The current workflow for visualization of genomic variant data from VCF files requires use of a combination of existing tools. Here, we describe VIVA (VIsualization of VAriants), a command line utility and Jupyter Notebook based tool for evaluating and sharing genomic data for variant analysis and quality control of sequencing experiments from VCF files. VIVA combines the functionality of existing tools into a single command to interactively evaluate and share genomic data, as well as create publication quality graphics.

Adipocytes initiate an adipose-cerebral-peripheral sympathetic reflex to induce insulin resistance during high-fat feeding
Authors: Cao Wei , Shi Meng , Wu Liling , Li Jiaxin , Yang Zhichen , Liu Youhua , Wilcox Christopher S. , Hou Fan Fan
Published: September 2019

The underlying mechanism by which amassing of white adipose tissue in obesity regulates sympathetic nerve system (SNS) drive to the tissues responsible for glucose disposal, and causes insulin resistance (IR), remains unknown. We tested the hypothesis that high-fat (HF) feeding increases afferent impulses from white adipose tissue that reflexively elevate efferent nerve activity to skeletal muscle (SM) and adipose tissue to impair their local glucose uptake. We also investigated how salt-intake can enhance IR. HF-fed rats received a normal salt (0.4%) or high salt (4%) diet for 3 weeks. High-salt intake in HF fed rats decreased insulin-stimulated 2-deoxyglucose uptake by over 30% in white adipose tissue and SM, exacerbated inflammation, and impaired their insulin signaling and glucose transporter 4 (Glut4) trafficking. Dietary salt in HF fed rats also increased the activity of the adipose-cerebral-muscle renin–angiotensin system (RAS) axes, SNS, and reactive oxygen species (ROS). Insulin sensitivity was reduced by 32% in HF rats during high-salt intake, but was improved by over 62% by interruption of central RAS and SNS drive, and by over 45% by denervation or deafferentation of epididymal fat (all P<0.05). Our study suggest that a HF diet engages a sympathetic reflex from the white adipose tissue that activates adipose-cerebral-muscle RAS/ROS axes and coordinates a reduction in peripheral glucose uptake. These are all enhanced by salt-loading. These findings provide new insight into the role of a reflex initiated in adipose tissue in the regulation of glucose homeostasis during HF feeding that could lead to new therapeutic approaches to IR.

Comparison between Modified MPC and DTC Control Method for Permanent Magnet Synchronous Motor
Authors: Li Huanyu , Li Miao , Zhengs Chenhong , Chen Bingqian
Published: September 2019

Direct torque control (DTC) and model predictive control (MPC) are widely used in the control of permanent magnet synchronous motor (PMSM). However, DTC for PMSM can cause large torque ripples and flux ripples, high harmonic distortion of the stator current, and high acoustic noises. Compared to DTC, MPC considers all possible switching states which can reduce the ripples of torque and flux. MPC with one-step delay compensation for PMSM and DTC with one-step delay compensation and two hysteresis comparators for PMSM have been proposed to solve some drawbacks of these two controllers. This paper makes a detailed comparison between these two improved control methods through Simulink and hardware experiments results to analyse the four indicators-torque ripple, flux ripple, transient time and THD of inverter current.
Transition bei ADHS
Authors: Alvarez Fischer Daniel , Zimmermann Carolin , Rudolph Frank Matthias , Bubenzer Rainer H. , Kis Bernhard
Published: September 2019

Der Übergang vom Kindesalter ins Erwachsenenalter stellt die Behandlung persistierender Erkrankungen wie die Aufmerksamkeitsdefizit-/Hyperaktivitätsstörung (ADHS) vor große Herausforderungen. Während noch 43 % aller Jugendlichen mit ADHS eine medikamentöse Behandlung erhalten, fällt dieser Anteil bei den Anfang zwanzigjährigen Patienten auf unter 20 % ab. Welche Faktoren eine Persistenz der ADHS vorhersagen ist nicht geklärt. Unter den Risikofaktoren finden sich aber neben einer erhöhten Krankheitsschwere auch komorbide Erkrankungen wie eine Depression. Der Artikel widmet sich der Frage nach Faktoren, die eine gelungene Transition begünstigen. Da in die Zeit der Transition die Berufswahl fällt, geht der Artikel der Frage nach, welche Voraussetzungen bei einer Tätigkeit gegeben sein sollten. Bis auf wenige Ausnahmen sind grundsätzlich jedoch alle Berufe für Menschen mit ADHS möglich. Abschließend geht der Artikel auf die Behandlungsmöglichkeiten und die Versorgungssituation für Patienten mit ADHS in Deutschland ein. Die Effektstärken einer medikamentösen Behandlung des ADHS sind hoch, ein Behandlungserfolg ist in den Zulassungsstudien > 60 % der Betroffenen zu erwarten. Eine Verhaltenstherapie (allein oder in Kombination mit Stimulanzien), Stimulanzien und Nichtstimulanzien sind in der Behandlung deutlich wirksamer als Placebo.

If the clamping force is too small, it may cause poor contact or even cause fire. In this paper, the 3D solid model of the puncture clamp is established by using SolidWorks 3D software. Then the finite element analysis model of the puncture clamp is established in the finite element analysis software ANSYS Workbench, and the static analysis and exploration of the puncture clamp are obtained. The results show that the puncture blade and the conductor on the puncture clamp have the greatest contact stress and the maximum amount of deformation of the bolt, while the bolt meets the required strength. The results can be used to further optimize the structural design of the puncture clamps, refine the installation specifications and guide the installation.

An algorithm for acceleration/deceleration control is proposed in this paper to improve the flexibility of the heavy-duty motion system. The algorithm is based on the five-segment S-type acceleration/deceleration curve. During the acceleration switching time, a circular arc is used to smooth the curve, and the running time of each stage could be reasonably allocated by cyclic iteration. A parameter is defined to quantify the degree of flexibility of the acceleration/deceleration process to match the actual project. This paper will build the model to compare the good and bad point of different algorithms. The result shows that the vibration and impact during the acceleration and deceleration process can be effectively reduced, which means that the flexibility of the system has been greatly improved.

Aiming at the multi-objective design problem for the refrigerated compartment, an optimal design model of the refrigerated compartment was established. The actual constraints of depreciation of insulating material for compartments increased the cost of transportation due to insulating materials and the cost of refrigeration due to compartment body transfer, compartment sealing and respiratory heat of cargo, its main design parameters were comprehensively considered. The maximum available space of the compartment and the minimum cost of single transporting were selected as objective function. Parameters of the refrigerated compartment were optimized with MATLAB software, and the available space of the refrigerated compartment and the cost of single transporting under different parameters were analyzed. Results showed that the optimized design method was suitable for refrigerated compartment. The optimized results of available space of refrigerated compartment and the cost of single transporting were different under different conditions. When the heat insulation material was respectively foaming with polystyrene, extruded polystyrene, polyurethane, in a longer transporting mileage from 50 to 500km, the corresponding optimal thickness of insulating materials of compartment body was thicker. Under the condition that the available space of refrigerated compartment reached the maximum and single transportation cost of the refrigerated compartment reached the minimum at the same time, when the average transporting mileage was 50km, the corresponding optimal thickness of heat insulation material was 0.11m with polystyrene, 0.09m with extruded polystyrene and 0.08m with polyurethane, while the available space of the refrigerated compartment was 12.0892m3, 12.7820m3, and 13.1375m3 respectively, and the corresponding cost of single transporting was CNY 5453.27, 4964.24 and 4847.98.

In order to ensure that the temperature of the main feed water and the main steam pipe is at the design value, there is a thick insulation layer outside the main pipe line. According to the requirements of the specification, after a certain period of time, the insulation layer here needs to be replaced. However, due to the relatively high dose of radioactivity here, maintenance personnel are subject to a certain dose of radiation. We use 3D ergonomics simulation method to establish a 3D model of the scene here, simulate the correct disassembly and installation process of the operator, make the maintenance personnel familiar with the environment and operation process, reduce errors, shorten the operation time, and finally shorten the inspection cycle. This achieves increased safety and reduced overhaul time at low cost.

In the past automatic measurement system for three-dimensional shape of complex parts, there was no corresponding measurement scheme for the groove-shaped complex parts, which there existed problems such as low work efficiency and large measurement error. In order to solve this problem, this paper is based on the principle of raster scanning projection measurement, and explores the mathematical model of projection grating trigonometry theory, and analyzes the different characteristics of scattered geometric features such as walls and edges inside the groove in complex parts. Combined with the scanning constraints such as the inclination angle and depth of field of the 3D scanner, the method of measuring the path planning of the groove-shaped complex parts was proposed and studied. Finally, the measurement path planning verification experiment was carried out, which is based on the above analysis. The results show that the position deviation during the measurement process is within 0.001mm, the angular deviation is within 0.009°, which proves the feasibility of the measurement path for the groove-shaped complex parts.

Published: September 2019

With the development of mobile devices, more and more location-based services (LBS) on the devices are needed and fingerprint indoor localization has become one most important technique because of its low cost and high accuracy. In this paper, we use the fingerprinting method which based on Channel State Information (CSI) for indoor localization. Furthermore, we extract the raw phase information from the multiple antennas and multiple sub-carriers through the IEEE 802.11n network interface card (NIC 5300) on several special models. Then we extract the required phase information and introduce two methods of mathematical statistics to analyse the feature of CSI signals. We replace the processed phase information with the signal features obtained from the analysis. For the offline stage, we employ a deep network with three hidden layers to train the signal features data, and use weights to represent fingerprints. Introducing a greedy learning algorithm to train the weights layer-by-layer to reduce the computational complexity, and the sub-network between two continuous layers forms a restricted Boltzmann machine (RBM). For the online location estimation, we use a probabilistic method based on the radial basis function (RBF). The neural network method we used this time is tested under two different scenarios, and different data are compared. The final conclusion is that the new method we combined is superior to the previous.

Published: September 2019

At present, with the construction and operation of new energy grid-connected and offshore wind power projects in China, DC XLPE cables have been widely used. Under the operating conditions, there are mainly two feasible technical means of DC cable insulation state detection, partial discharge (PD) and leakage current. However, it is still a blank in the world to apply it to the validity and condition of DC cable operation detection. Based on the semi-conductive layer residual defect model of XLPE cable, the characteristics of PD and leakage current under different voltage values and polarities are studied by setting up an experimental platform for detecting PD and leakage current of DC XLPE cable. The results show that both PD and leakage current can detect cable defects, among which PD is easier to detect cable defects under negative polar voltage and higher voltage. Leakage current characteristics change obviously under positive polar voltage. When applied voltage is lower than rated voltage, obvious changes can also be measured. In this paper, the feasibility of live detection of leakage current of DC cables under operating conditions is proposed, which is of great value to improve the detection capability of DC XLPE cables.
