Influence of wireless communication transport latencies and dropped packages on vehicle stability with an offsite steering controller
Authors: Bennett Rory , Kapp Reyn , Botha Theunis R. , Els Schalk 
Published: March 2020

In recent years, advanced driver assistance systems (ADASs) have been used to improve the safety of vehicles by either providing additional information to the driver or by taking over complete control. The majority of ADASs currently being utilised run entirely on the vehicle, only having access to information provided by the sensors that are onboard the vehicle itself. Part of the next step in the evolution of ADAS is to incorporate information from other offsite sensors or obtain control inputs from infrastructure which can coordinate multiple vehicles simultaneously via a wireless interface. Wireless communication is inherently delayed and prone to dropped packets. This study looks at the effect of transport latencies and dropped packets on an off‐site autoregressive steering controller supplying direct steering inputs to a vehicle. A fully non‐linear vehicle simulation model is used to test the effect of delaying steering inputs and dropped packets to test the stability of the controller. The study shows that at dropped packet percentages of up to 40% adequate vehicle control is maintained, while transport latencies of up to 100 ms allow for moderately accurate vehicle control.

Published: March 2020

Abstract
Objective This study aims to determine the topographic localization of the stylomastoid foramen (SF) and its morphometric relationship with the surrounding bony landmarks.
Design A descriptive anatomical study.
Setting Anatomy Laboratory of the Faculty of Medicine.
Participants Measurements were performed on 53 dry temporal bones.
Main Outcome Measures On the inferior and lateral aspects of photographic images, lines and angles were defined. The most lateral end of the SF (SF1) and the transverse medial–lateral line that passes through the upper end of the anterior border of mastoid process (line 1) were used as reference points for topographic evaluation. The upper end of the anterior border of mastoid process (A) and the tip of mastoid process (B) were considered in defining angles. The dates about SF were evaluated using the ImageJ 1.46r software and digital caliper.
Results SF1 was classified into three different types based on its topographical localization, stated as Type 1, Type 2, and Type 3. In Type 1, SF1 was located anterior to line 1 (54.7%). SF1 was located posterior to line 1 in Type 2 (34.0%). SF1 was located just over line 1 in Type 3 (11.3%). We also detected angular variations between these types in the inferior and lateral aspects.
Conclusion The recommended angles of application are 30 degrees on the horizontal plane and 55 degrees on the sagittal plane for Type 1 when point B is considered. A needle length below 10 mm is more suitable to minimize the potential complications of the nerve block.

Published: March 2020

Abstract
Objective This study proposes to present reference parameters for trigeminal (V) and facial (VII) cranial nerves (CNs)-triggered electromyography (tEMG) during endoscopic endonasal approach (EEA) skull base surgeries to allow more precise and accurate mapping of these CNs.
Study Design We retrospectively reviewed EEA procedures performed at the University of Pittsburgh Medical Center between 2009 and 2015. tEMG recorded in response to stimulation of CN V and VII was analyzed. Analysis of tEMG waveforms included latencies and amplitudes. Medical records were reviewed to determine the presence of perioperative neurologic deficits.
Results A total of 28 patients were included. tEMG from 34 CNs (22 V and 12 VII) were analyzed. For CN V, the average onset latency was 2.9 ± 1.1 ms and peak-to-peak amplitude was 525 ± 436.94 μV (n = 22). For CN VII, the average onset latency and peak-to-peak amplitude were 5.1 ± 1.43 ms and 315 ± 352.58 μV for the orbicularis oculi distribution (n = 09), 5.9 ± 0.67 ms and 517 ± 489.07 μV on orbicularis oris (n = 08), and 5.3 ± 0.98 ms 303.1 ± 215.3 μV on mentalis (n = 07), respectively.
Conclusion Our data support the notion that onset latency may be a feasible parameter in the differentiation between the CN V and VII during the crosstalk phenomenon in EEA surgeries but the particularities of this type of procedure should be taken into consideration. A prospective analysis with a larger data set is necessary.
Tumor-to-Tumor Metastasis of Multiple Meningiomas and Clear Cell Renal Cell Carcinoma Metastasis as First Clinical Appearance of Kidney Cancer: A Case Report and Analysis
Authors: Dietterle Johannes , Frydrychowicz Clara , Müller Wolf , Hoffmann Karl-Titus , Jähne Katja , Meixensberger Jürgen 
Published: March 2020

Abstract
Background Meningioma accounts for more than 35% of all diagnosed brain tumors of the central nervous system and, moreover, it is the most common benign recipient of tumor-to-tumor metastasis. Several cases with tumor-to-meningioma metastasis by breast, lung, and intestinal cancer have been described before.
Case description The case of a patient with a longstanding history of multiple meningiomas (n = 4) that suddenly became symptomatic and progressive in size is presented. Following extirpation of the two largest meningiomas, a histological examination revealed two separate tumor-to-meningioma metastases of clear cell renal cell carcinoma that was undiagnosed before. Post-surgical computed tomography scan then confirmed tumor-suspect lesions in both kidneys. After recovery and rehabilitation, adjuvant radio-chemo-therapy was applied according to protocols for kidney cancer. No other tumor-to-tumor-suspect event occurred since then for the remaining two meningiomas.
Conclusion Review of literature and our case strengthens the idea of meningioma as a favorable premetastatic niche. Considering that the patient lived with a stable disease for many years, a sudden progress of tumor size in association with neurological deterioration was highly suspected for malign involvement, including the possibility of tumor-to-tumor metastasis. Physicians should be aware about this phenomenon and treat patients accordingly to the underlying disease.

Published: March 2020

Abstract
Objective This study aimed to evaluate surgical outcomes after transzygomatic middle cranial fossa (MCF) (TZ-MCF) approach for tumor control in patients with large skull base lesions involving the MCF and adjacent sites.
Setting This study was done at the tertiary skull base center.
Design This is a retrospective case series.
Main Outcome Measures The main outcome measures were tumor control (recurrence), new-onset cranial neuropathies, facial nerve and audiometric outcomes, cerebrospinal fluid (CSF) leak, and wound complications.
Results Sixteen patients were identified with a median age of 45 years (range: 20–72). The mean maximum tumor dimension was 5.49 cm (standard deviation [SD]: 1.2, range: 3.1–7.3) and the mean tumor volume was 28.5 cm3 (SD: 18.8, range: 2.9–63.8). Ten (62.5%) tumors were left sided. The most common pathology encountered was meningioma (n = 7) followed by chondrosarcoma (n = 4). Mean follow-up was 36.3 (SD: 26.9) months. Gross total resection or near total resection was achieved in nine (56.2%) and planned subtotal resection was used in seven (43.7%). Postoperative additional new cranial nerve (CN) deficits included CN V (n = 1), CN III (n = 2), CN VI (n = 1), and CN X (n = 1). Major neurological morbidity (hemiplegia) was encountered in two patients with resolution. There were no cases of CSF leak, meningitis, hemorrhage, seizures, aphasia, or death. There was no recurrence or regrowth of residual tumor. Facial nerve function was preserved in all but one patient (House–Brackmann grade 2).
Conclusion Various skull base tumors involving MCF with extension to adjacent sites can be successfully resected using the TZ-MCF approach in a multidisciplinary fashion. This approach yields optimal exposure and permits excellent tumor control with acceptable CN and neurological morbidity.

Authors: Lu Yao , Hao Huilian , Liu Pengcheng , Feng Yibo , Wang Jianjun 
Published: March 2020

Abstract
Graphene quantum dots (GQDs) have been synthesized via one-pot hydrothermal approach using glucose as precursors. The obtained products have a size around 3.5 nm, which can be controlled by changing the reaction temperature. With the increase of preparation temperatures, the glucose molecules are dehydrated under hydrothermal conditions and then converted to GQDs. The high temperature helps to increase the graphitization degree of GQDs. The GQDs show the blue color emission under excitation of 300-450 nm, which can be used in electrochemical luminescence devices.

Authors: Zhang Qingquan , Zheng Yunhong , Huang Xumin , Gao Haiyan , Yang Guizhi 
Published: March 2020

Abstract
Aiming at the speed sensorless control system of permanent magnet synchronous motor which embedded in rotor magnet steel, a new method for detecting the initial position of the rotor is proposed in this paper. This method is injecting a high-frequency rotating voltage to generate a high-frequency current in the stator windings that contains the spatial position information of the rotor. Compared with the traditional high-frequency injection method, this paper uses Discrete Fourier Transform (DFT) to demodulate high-frequency current. It avoids the signal phase delay caused by the use of a large number of filters when demodulating the traditional heterodyne method. At the same time, this method has nothing to do with the initial phase of the injected signal. Compared with the heterodyne method, the extracted rotor position angle is more accurate, and the structure is simple Number system. The validity and feasibility of the method are verified by simulation and experimental platform based on dSPACE.

Authors: Zhou Xia , Liu Sha 
Published: March 2020

AbstractThe LSSVM-based NARMAX model and the identification of the model are studied in the paper. By extending the immune cell subset theory and clone selection principle, a novel adaptive immune multiobjective algorithm (AIMA) is proposed. It is shown that, according to the variation of subsets in the memory set, the AIMA can produce different cell subsets adaptively, and thus regulate the related model parameters adaptively to realize the optimization. The simulation result demonstrates that with the parameters identified by the AIMA, the LSSVM-based NARMAX model has a satisfactory accuracy and it can be used to solve dynamic modeling problems.

Published: March 2020

Abstract
From the perspective of competition, the competition of value chain has gradually become the main form of competition among enterprises, and is no longer merely the internal competition between enterprises. At the same time, the upstream and downstream related industries as well as the competition between peer enterprises also came. As one of the important ways to create enterprise value, cost management should adapt to the changes in the market environment. If enterprises want to reduce enterprise costs on the premise of ensuring product market demand, they can apply value chain cost management to achieve cost minimization and value maximization through strengthening and improving each link.

Published: March 2020

Abstract
Urban rail transit projects have large investment, long construction period, large scale, and complex professional technology, which leads to problems such as cumbersome construction management and unclear regulatory content. Based on grounded theory, this study uses semi-structured interviews to determine the core content of project supervision: market supervision, contract supervision, and administrative supervision. This paper constructs the supervision content demand model of the urban rail transit project general contracting project, and analyzes the three types of supervision content from the perspective of the government to enhance the government’s supervision awareness and optimize the supervision content.

Published: March 2020

Abstract
Transfer entropy (TE) has been broadly used in the field of neurosciences. In this paper, the partial information decomposition algorithm is employed to decompose multivariate TE into synergistic, redundant and unique parts. In this work, the synergistic part is believed as more suitable as the computation method. We recorded the magnetoencephalogram (MEG) data of 6 subjects with depression and 13 normal subjects under different emotional stimulations, and studied the coupling between multiple symmetric channels in the frontal area in the brain of subject. The experimental results show that under different emotional stimulations, normal people present significant difference from the depression patients, especially in the right frontal area. Furthermore, under negative emotional stimulation, the difference in synergistic value between normal people and depression patients is smaller. The synergistic value of depression patients has become bigger, which indicates that the brain complexity of depression patients has grown, and their brain activities have increased.

Published: March 2020

AbstractDue to the large number of sources and wide area of domestic sewage, the sewage treatment facilities in Kunming are mainly distributed in scattered market towns and villages and have a wide variety. With the wide application of IoT technology, sewage treatment plants are heading towards intelligence and unmanned technology, with better treatment monitoring, higher treatment quality and lower operation cost. Based on IoT technology, this paper constructed an intelligent system for monitoring and management in sewage treatment plants in Dianchi lake basin and Niulan river basin. The overall architecture of the system was achieved by modularized function design, and was divided into three systems : device end system, network transmission system and application management system. This system realizing centralized management and display can monitor the operating status of sewage treatment process online, improve the efficiency of facility management and operation, as well as the work efficiency of relevant departments. The dilemma related to sewage management in Dianchi lake basin and Niulan river basin can be solved significantly.

Published: March 2020

Abstract
The paper considers a new approach to determining the external noise of road construction and earthmoving machines. The article shows that the existing method gives overestimated measurement results for earth moving vehicles. It was also revealed that due to the fact that the known methods for determining the external noise of road construction machines do not give a real picture of the external noise emitted by the machines, there are no devices for measuring the real noise of the vehicles. The authors provide the results of experimental studies performed at the plant of JSC “Bryansk Arsenal”.

Abstract

Background
Multi-morbidity and polypharmacy increase the risk of non-trivial adverse drug reactions (ADRs) in older people during hospitalization. Despite this, there are no established interventions for hospital-acquired ADR prevention.

Methods
We undertook a pragmatic, multi-national, parallel arm prospective randomized open-label, blinded endpoint (PROBE) controlled trial enrolling patients at six European medical centres. We randomized 1,537 older medical and surgical patients with multi-morbidity and polypharmacy on admission in a 1:1 ratio to SENATOR software-guided medication optimization plus standard care (intervention, n = 772, mean number of daily medications = 9.34) or standard care alone (control, n = 765, mean number of daily medications = 9.23) using block randomization stratified by site and admission type. Attending clinicians in the intervention arm received SENATOR-generated advice at a single time point with recommendations they could choose to adopt or not. The primary endpoint was occurrence of probable or certain ADRs within 14 days of randomization. Secondary endpoints were primary endpoint derivatives; tertiary endpoints included all-cause mortality, re-hospitalization, composite healthcare utilization and health-related quality of life.

Results
For the primary endpoint, there was no difference between the intervention and control groups (24.5 vs. 24.8%; OR 0.98; 95% CI 0.77–1.24; P = 0.88). Similarly, with secondary and tertiary endpoints, there were no significant differences. Among attending clinicians in the intervention group, implementation of SENATOR software-generated medication advice points was poor (~15%).

Conclusions
In this trial, uptake of software-generated medication advice to minimize ADRs was poor and did not reduce ADR incidence during index hospitalization.

Abstract
We studied whether exposure to parental smoking in childhood/adolescence is associated with midlife cognitive function, leveraging data from the Cardiovascular Risk in Young Finns Study. A population-based cohort of 3,596 children/adolescents aged 3–18 years was followed between 1980 and 2011. In 2011, cognitive testing was performed on 2,026 participants aged 34–49 years using computerized testing. Measures of secondhand smoke exposure in childhood/adolescence consisted of parental self-reports of smoking and participants’ serum cotinine levels. Participants were classified into 3 exposure groups: 1) no exposure (nonsmoking parents, cotinine &lt;1.0 ng/mL); 2) hygienic parental smoking (1–2 smoking parents, cotinine &lt;1.0 ng/mL); and 3) nonhygienic parental smoking (1–2 smoking parents, cotinine ≥1.0 ng/mL). Analyses adjusted for sex, age, family socioeconomic status, polygenic risk score for cognitive function, adolescent/adult smoking, blood pressure, and serum total cholesterol level. Compared with the nonexposed, participants exposed to nonhygienic parental smoking were at higher risk of poor (lowest quartile) midlife episodic memory and associative learning (relative risk (RR) = 1.38, 95% confidence interval (CI): 1.08, 1.75), and a weak association was found for short-term and spatial working memory (RR = 1.25, 95% CI: 0.98, 1.58). Associations for those exposed to hygienic parental smoking were nonsignificant (episodic memory and associative learning: RR = 1.19, 95% CI: 0.92, 1.54; short-term and spatial working memory: RR = 1.10, 95% CI: 0.85, 1.34). We conclude that avoiding childhood/adolescence secondhand smoke exposure promotes adulthood cognitive function.
