Practical High-Resistivity Silicon-on-Insulator Solution for Spiral Inductors in Radio-Frequency Integrated Circuits

The effect of high-resistivity (high-R) silicon-on-insulator (SOI) substrates on spiral inductors in radio-frequency integrated circuits (RF ICs) has been investigated by experiment and simulation. The effect of the high-R substrates on the spiral inductors saturates at a resistivity above 2–3 kΩ cm, and the resistivity must be maintained high with a thickness of about 300 µm. The resistivity dependence of the high-R effect can be explained with a dielectric loss mechanism in silicon substrates. The thickness criterion of the effect can be explained with an inductor model that includes magnetically induced current in a ground plane. On the basis of experimental results and discussion, we conclude that a commercially available high-R wafer with carefully designed back-end process is sufficient for obtaining the maximum effect of high-R substrates.
A new torque and flux control method for switched reluctance motor drives

Switched reluctance (SR) motors have an intrinsic simplicity and low cost that make them well suited to many applications. However the motor's doubly salient structure and highly nonuniform torque and magnetization characteristics lead to the inability to excite the motor using conventional AC motor waveforms, or apply established AC motor rotating field theory to the motor. Furthermore, high torque ripple is inherent in the motor unless a torque ripple reduction strategy is employed. Thus, control of the motor is difficult and complex compared to other machines. Previous methods of control have fallen into two main categories: those which use a simplified linear model and those which account for the motor saturation. The simplified linear model schemes have the advantage of simplicity and tractability but are inaccurate in most practical SR drives, whereas the nonlinear schemes have the problem of high complexity and computational expensiveness which makes real-time implementation difficult. To overcome these problems, in this paper, a novel control method for the SR motor is derived from analysis of the nonuniform torque characteristics of the motor. The control method applies the philosophy of direct torque control (DTC). Unlike previous direct torque control schemes for the SR motor drive, the new method does not involve short flux patterns, a change of the motor winding configuration, or the use of a bipolar current drive. Thus, the scheme can be conveniently implemented on any normal type of SR motor drive. In addition, the scheme overcomes the problems associated with torque ripple control in the SR motor by regulating the torque output of the motor within a hysteresis band. Furthermore, the scheme is very simple and can be implemented in real-time with low cost microprocessor hardware.
ENVIRONMENTAL PROTECTION INVESTMENT AND BUSINESS PERFORMANCE OF ENTERPRISES UNDER THE INFLUENCE OF ENVIRONMENTAL REGULATION

The 11th Five-Year Plan of China has established obligatory targets for main pollutant emissions while the completion of the targets has been associated with the achievements of local officials. With the full implementation of this plan, many enterprises began to take forward-looking environmental protection strategies to cope with the increasingly stringent environmental regulations. Most of the existing literature have systematically studied the impact of environmental regulation from the perspective of industry or region, but they have not considered the dynamic response of enterprises to environmental regulation. The research on the economic consequences of enterprises adopting forward-looking environmental protection strategies for environmental protection investment at the micro level is relatively insufficient. This paper uses the data of China's listed manufacturing companies from 2011 to 2017 to study the effect of environmental protection investment on their business performance of enterprises. The results show that environmental protection investment has a positive cumulative effect on company’s business performance, especially in non-state-owned enterprises. Based on this conclusion, this paper puts forward relevant policy suggestions to promote enterprises to implement forward-looking environmental protection strategy and gain competitive advantage.
Adjuvant Radiotherapy Is Associated with an Increase in the Survival of Old (Aged over 80 Years) and Very Old (Aged over 90 Years) Women with Breast Cancer Receiving Breast-Conserving Surgery

This study is the first to examine the effect of adjuvant whole-breast radiotherapy (WBRT) on oncologic outcomes such as all-cause death, locoregional recurrence (LRR), and distant metastasis (DM) in old (aged ≥80 years) and very old (aged ≥90 years) women with breast invasive ductal carcinoma (IDC) receiving breast-conserving surgery. After propensity score matching, adjuvant WBRT was associated with decreases in all-cause death, LRR, and DM in old and very old women with IDC compared with no use of adjuvant WBRT. Background: To date, no data on the effect of adjuvant whole-breast radiotherapy (WBRT) on oncologic outcomes, such as all-cause death, locoregional recurrence (LRR), and distant metastasis (DM), are available for old (aged ≥80 years) and very old (≥90 years) women with breast invasive ductal carcinoma (IDC) receiving breast-conserving conservative surgery (BCS). Patients and Methods: We enrolled old (≥80 years old) and very old (≥90 years old) women with breast IDC who had received BCS followed by adjuvant WBRT or no adjuvant WBRT. We grouped them based on adjuvant WBRT status and compared their overall survival (OS), LRR, and DM outcomes. To reduce the effects of potential confounders when comparing all-cause mortality between the groups, propensity score matching was performed. Results: Overall, 752 older women with IDC received BCS followed by adjuvant WBRT, and 752 with IDC received BCS with no adjuvant WBRT. In multivariable Cox regression analysis, the adjusted hazard ratio (aHR) and 95% confidence interval (95% CI) of all-cause death for adjuvant WBRT compared with no adjuvant WBRT in older women with IDC receiving BCS was 0.56 (0.44–0.70). The aHRs (95% CIs) of LRR and DM for adjuvant WBRT were 0.29 (0.19–0.45) and 0.45 (0.32–0.62), respectively, compared with no adjuvant WBRT. Conclusions: Adjuvant WBRT was associated with decreases in all-cause death, LRR, and DM in old (aged ≥80 years) and very old (aged ≥90 years) women with IDC compared with no adjuvant WBRT.
Measuring Variability in Traffic Conditions by Using Archived Traffic Data

The predictability of transportation service is of great importance to travelers. Whereas most transportation performance measures deal more directly with congestion, such as through delay measures, few quantify the level of predictability of travel. A new measure that effectively measures predictability of transportation service, the variability index, was developed and demonstrated. The variability index is a good example of the application of data mining in large transportation databases. Conceptually based on multivariate statistical quality control (MSQC), the variability index is computed by measuring the size (spatial volume) of the confidence regions defined by MSQC by using large sets of archived traffic data. In other words, experience (archived traffic data) is mined to measure the level of variability experienced by time and location. A case study application of this procedure demonstrates how this measure can clearly identify times of day and days of the week that experience relatively high degrees of variability in traffic conditions—or less predictable service for the traveler.
Photovoltaic Power Plant Collection and Connection to HVDC Grid with High Voltage DC/DC Converter

Photovoltaic (PV) power plant collection and connection to a high voltage direct current (HVDC) grid has many advantages. Compared with the traditional AC collection and grid-connection scheme, it can reduce the power conversion links and improve the system efficiency. As one of the most important devices in the application of a PV HVDC collection and grid-connection system, a high voltage, large capacity, high step-up ratio DC/DC converter is the critical technology. A DC/DC converter scheme based on a boost full bridge isolated power module cascaded in input parallel output series (IPOS) structure is proposed to meet the technical requirements of PV power conversion with high voltage, large capacity, and high step-up ratio. The operation mode of the power module is analyzed, the soft switching method is proposed, and the constraint to realize the soft switching of the power module is deduced. Aiming to resolve the problem of multi-module voltage and current equalization in a cascaded DC/DC converter, a distributed module equalization control strategy is proposed to realize the reliable operation of a power module and converter. A 5 kV/80 kW standard power module is developed, the DC/DC converter experimental platform is built, and the proposed system scheme and control strategy are verified by experiments. Based on a 14-power module input parallel output series connection, a ±30 kV/1 MW PV DC/DC converter is developed, a ±30 kV PV HVDC collection and grid-connection demonstration system is established, and the experimental test is completed to realize the stable operation of the system.
Coming attractions in software architecture

Software architecture has emerged as an important topic in software engineering. This paper examines what is new about the subject, and what is not, and what research trends we may expect in the future. We discuss the promise that work in the field holds, and organize the work into five predominant themes: selection, representation, evaluation, development, and recovery. Technology for the formal representation of architectures is examined in detail, along with notions of architectural styles and patterns. The paper begins by examining the range of meanings associated with the term in order to provide a context for its treatment.

Proceedings of the First International Conference on Transportation Information and Safety, held in Wuhan, China, June 30-July 2, 2011. Sponsored and organized by Wuhan University of Technology; Transportation and Development Institute of ASCE; China Communications and Transportation Association; National Natural Science Foundation of China; Canadian Society for Civil Engineering. This collection contains 355 reviewed papers examining the problems and opportunities addressed by a multimodal approach for the sustained development of the transportation system in China. Modern information technologies and innovations in transportation safety management are key to improving the system efficiency and enhancing traffic safety. Multimodal and system-wide approaches are needed to develop solutions that are technically effective, socially equitable, environmentally sound, and economically viable. These papers promote sustainable transportation system development in the context of information systems and safety for four transportation areas: highways, air, rail, and water.
In Vitro Fertilization Using Preimplantation Genetic Testing in a Romanian Couple Carrier of Mutations in the TTN Gene: A Case Report and Literature Review

Severe congenital myopathy with fatal cardiomyopathy (EOMFC) is a rare genetic neuromuscular disorder inherited in an autosomal recessive manner. Here we presented a successful pregnancy obtained by in vitro fertilization (IVF) using preimplantation genetic testing (PGT) in one young Romanian carrier couple that already lost mutation(s) within the TNN gene and whose first baby passed away due to multiple complications. It was delivered via emergency C-section at 36 weeks and fully dependent on artificial ventilation for a couple of months, weighing 2200 g and an APGAR score of 3. The aCGH + SNP analysis revealed an abnormal profile of the first newborn; three areas associated with loss of heterozygosity on chromosome 1 (q25.1–q25.3) of 6115 kb, 5 (p15.2–p15.1) of 2589 kb and 8 (q11.21–q11.23) of 4830 kb, a duplication of 1104 kb on chromosome 10 in the position q11.22, and duplication of 1193 kb on chromosome 16 in the position p11.2p11. 1. Subsequently, we proceeded to test the parents and showed that both parents are carriers; confirmed by Sanger and NGS sequencing—father—on Chr2(GRCh37):g. 179396832_179396833del—TTN variant c. 104509_104510del p.(Leu34837Glufs*12)—exon 358 and mother—on Chr2(GRCh37):g.179479653G>C—TTN variant c.48681C>G p.(Tyr16227*)—exon 260. Their first child died shortly after birth due to multiple organ failures, possessing both parent’s mutations; weighing 2200 g at birth and received an APGAR score of 3 following premature delivery via emergency C-section at 36 weeks. Two embryos were obtained following the IVF protocol; one possessed the mother’s mutation, and the other had no mutations and was normal (WT). In contrast with the first birth, the second one was uneventful. A healthy female baby weighing 2990 g was delivered by C-section at 38 weeks, receiving an APGAR score of 9.
Autonomous driving on a road network

In order to drive a vehicle without manual intervention, short range information about the visible surrounding in front of the vehicle is extracted by machine vision: a fast, region-based tracking of lane boundaries and-at a lower frequency-an evaluation of the entire video imag in order to detect intersections. This is combined with internal map-based knowledge about the road network, which is supplied by the navigation system Travelpilot, commercially offered by Robert Bosch GmbH. The modules have been integrated into an experimental vehicle. Given a desired goal-position on a suitable selected road network, the vehicle is able to perform the necessary driving mission autonomously. <<ETX>>
Study on Irrigation Model Based on Plant Ultrasonic Acoustic Emissions

Produced by cohesion between water molecules or adhesion to the conduit wall, the plant cavitation is accompanied by the vessel walls vibration which is the indicator of the water stress. The ultrasonic acoustic emissions (UAEs) are used to detect the plant cavitation events which are the transmission of vibration. The UAEs could be detected in ultrasonic frequencies between 100K Hz and 1 MHz. The PCI-2 data acquisition (DAQ) equipment and R15 sensors are used to improve the precision of cavitation detection. When the water stress and dehydration gets heavier, the UAEs rate gets higher. Use the tomato practice data with the empirical deduction under the modern greenhouse conditions, the UAEs and Transpiration Index (UAETI) and the UAEs Irrigation Index (UAEII) irrigation model are draw from the relationship between transpiration and UAEs. UAETI can be used to analysis the transpiration, and UAEII can be used to analysis the irrigation time. It is better to use UAEs technique to carry out automatic and precise irrigation for the plant and to improve the effect of Water-saving irrigation.
Structure from motion with planar homography estimation: a real-time low-bandwidth, high-resolution variant for aerial reconnaissance

We propose a new algorithm variant for Structure from Motion (SfM) to enable real-time image processing of scenes imaged by aerial drones. Our new SfM variant runs in real-time at 4 Hz equating to an 80× computation time speed-up compared to traditional SfM and is capable of a 90% size reduction of original video imagery, with an added benefit of presenting the original two-dimensional (2D) video data as a three-dimensional (3D) virtual model. This opens many potential applications for a real-time image processing that could make autonomous vision–based navigation possible by completely replacing the need for a traditional live video feed. The 3D reconstruction that is generated comes with the added benefit of being able to generate a spatially accurate representation of a live environment that is precise enough to generate global positioning system (GPS) coordinates from any given point on an imaged structure, even in a GPS-denied environment.
Improved Decomposition Strategy for Joint Entity and Relation Extraction

The joint entity and relation extraction task detects entity pairs along with their relations to extract relational triplets. A recent study (Yu et al. 2020) proposed a novel decomposition strategy that splits the task into two interrelated subtasks: detection of the head-entity (HE ) and identification of the corresponding tail-entity and relation (TER) for each extracted head-entity. However, this strategy suffers from two major problems. First, if the HE detection task fails to find a valid headentity, the model will then miss all related triplets containing this head-entity in the head role. Second, as Yu et al. (2020) stated, their model cannot solve the entity pair overlap (EPO) problem. For a given head-entity, the TER extraction task predicts only a single relation between the head-entity and a tail-entity, even though this entity pair can hold multiple relations. To address these problems, we propose an improved decomposition strategy that considers each extracted entity in two roles (head and tail) and allows a model to predict multiple relations (if any) of an entity pair. In addition, a corresponding model framework is presented to deploy our new decomposition strategy. Experimental results showed that our approach significantly outperformed the previous approach of Yu et al. (2020) and achieved state-of-the-art performance on two benchmark datasets.
Implementation of a battery back-up system for generator set downsizing

A battery back-up system coupled to a micro grid network through a 2-level inverter/rectifier module has been designed and implemented. The local grid is primarily supplied by one diesel generator set (genset) and the battery back-up system can be connected to the grid if required to. The 2-level inverter/rectifier module consists of 6 IGBTs distributed in three legs with their anti-parallel diodes respectively. The system operates in three modes: charging, paralleling and stand-alone. Depending on the operation mode, the 2-level IGBT module acts as rectifier or as an inverter. When the system is operating in charging mode, the 2-level module acts as an active rectifier and its output is used to charge the two battery packs, which are connected in series. In the charging mode the batteries are firstly charged in current mode and then in voltage mode to maintain the charge. These batteries are used to supply the system when it is operating in paralleling or stand-alone mode. In the stand-alone mode, the system is capable of maintaining the output voltage when operating in unbalanced load conditions.
Effects of uniform-allocation constraints in networked common-pool resource extraction games

Communities that share common-pool resources (CPRs) often coordinate their actions to sustain resource quality more effectively than if they were regulated by some centralized authority. Networked models of CPR extraction suggest that the flexibility of individual agents to selectively allocate extraction effort among multiple resources plays an important role in maximizing their payoffs. However, empirical evidence suggests that real-world CPR appropriators may often de-emphasize issues of allocation, for example by responding to the degradation of a single resource by reducing extraction from multiple resources, rather than by reallocating extraction effort away from the degraded resource. Here, we study the population-level consequences that emerge when individuals are constrained to apply an equal amount of extraction effort to all CPRs that are available to them within an affiliation network linking agents to resources. In systems where all resources have the same capacity, this uniform-allocation constraint leads to reduced collective wealth compared to unconstrained best-response extraction, but it can produce more egalitarian wealth distributions. The differences are more pronounced in networks that have higher degree heterogeneity among resources. In the case that the capacity of each CPR is proportional to its number of appropriators, the uniform-allocation constraint can lead to more efficient collective extraction since it serves to distribute the burden of over-extraction more evenly among the network’s CPRs. Our results reinforce the importance of adaptive allocation in self-regulation for populations who share linearly degrading CPRs; although uniform-allocation extraction habits can help to sustain higher resource quality than does unconstrained extraction, in general this does not improve collective benefits for a population in the long term.
Urgent-Start Peritoneal Dialysis: A Comparison of Catheter Insertion Using Seldinger Technique and Surgical Operation

Background: Urgent-Start Peritoneal Dialysis (USPD) is increasingly used worldwide and represents a safe, convenient and cost-effective method to initiate dialysis. However, good catheter insertion techniques are imperative to avoid postoperative complications. While percutaneous catheter insertion by Seldinger technique is considered a safe method with few post-operative complications, comparisons with surgical operation technique are needed, especially in China, where there a few reports on the outcome of percutaneous catheter insertion by Seldinger technique in USPD patients.
A New Prognostic and Therapeutic Immune-related Risk Signature of Colorectal Cancer

BackgroundAlthough some advanced colorectal cancer (CRC) patients could select immunotherapy, but still most microsatellite stability (MSS) CRC patients did not respond. Our present study aims to set up a novel system for prognostic prediction and immunotherapeutic responsiveness for MSS CRC patients.MethodsUnivariable Cox regression survival analysis and least absolute shrinkage and selector operation (LASSO) regression analysis were performed to identify prognostic genes and establish immune risk signatures. Multivariate Cox regression analysis was performed to verify whether these clinical features could predict prognosis. R package was used to analyze the relationship between the immune-related risk model and these immune cells, effector molecules, and immune checkpoints.ResultsWe constructed an immune-related signature and verified its predictive capability. Immune-related signature included 12 differentially expressed IRGs (12 DE IR MSSGs), including CXCL1, CD36, FABP4, MS4A2, NRG1, VGF, GRP, HDC, XCL1, NGF, MAGEA1, and IL13. The signature consisting of 12 DE IR MSSGs was an independent and effective prognostic factor for the overall survival of CRC patients. In addition, the signature consisting of 12 DE IR MSSGs reflected the infiltration characteristics of different immunocytes in tumor immune microenvironment. The signature consisting of 12 DE IR MSSGs also had a significant correlation with immune checkpoint molecules.
