Bibliometric analysis of research on thyroid ultrasonography.

Background The incidence of thyroid diseases has increased, which may be partly related to the widespread use of thyroid ultrasound resulting in a large number of asymptomatic thyroid nodules to be found. Research has found that many thyroid ultrasound examinations are completely avoidable. However, the purpose of the present study was to use bibliometrics to analyze the relevant research literature of thyroid ultrasound and understand the overall status of the current research in this field. Methods We searched the Science Citation Index Expanded (SCI-E) database in the Web of Science Core Collection. Search terms were "ultrasonography" and "thyroid gland". The date range for the document search was from 1900 to May 10, 2021. Export the full record of the search results and the references in txt. format, and use the CiteSpace software to analyze the annual publication of literatures, the distribution of countries and institutions where the literatures came from, the distribution of journals and authors. The keywords used in the literature were also analyzed. Results A total of 1,241 publications were included in the results, and the frequency of citations was 27,149. The top 5 countries for the number of publications published were the USA, Turkey, Italy, South Korea, and China; the top 5 countries by centrality were the USA, Germany, Italy, Canada, and China. The number of institution-published papers was generally low, and the centrality score was low. Research in this field was relatively scattered among institutions and cooperation between institutions was few. There was little collaboration between authors from different institutions. The most cited authors were mainly from European and North American countries. Journals, such as Thyroid, Journal of Clinical Ultrasound, and Journal of Endocrinological Investigation, had great influence in this field. Keyword analysis results showed that research is mainly focused on the differentiation of benign and malignant thyroid nodules. Conclusions There was an increase in thyroid ultrasound research, but there was few cooperation exist between institutions. The main research direction was the differentiation of benign and malignant thyroid nodules.
Asymmetry issues in power system restoration

This paper is one of a series presented on behalf of the Transmission Operation Subcommittee with the intent of focusing attention on EHV asymmetry issues during restoration. Many existing EHV lines have unsymmetrical (horizontal) conductor spacing without being transposed. These characteristics generate unacceptable negative sequence currents (NSC). Under light-load condition and during restoration, NSC has caused cascade tripping of a number of generators resulting in an area wide blackouts, has prevented synchronization of incoming generators, and has blocked remote cranking of thermal units. The paper describes a simple and approximate method for assessing the extent of NSC in EHV lines and then determining corrective measures. It recommends that when attempting to provide an offsite source to a thermal power plant the extent of NSC be determined and if unacceptable, either the operation be deferred to after the initial restoration phase, or the appropriate "underlying load" be determined for connection to the receiving end of the EHV lines.
Broadside Radiating, Low-Profile, Electrically Small, Huygens Dipole Filtenna

An electrically small, low-profile, Huygens dipole filtenna is presented that operates near 1.28 GHz. The design incorporates a pair of magnetic and electric near-field resonant parasitic (NFRP) elements and a driven element. Two pairs of interdigitated capacitor structures are integrated into the magnetic NFRP element to produce two deep radiation nulls at both the lower and upper frequency edges of the passband, respectively. The two nulls can be independently controlled to achieve good out-of-band suppression levels. A prototype was fabricated and tested. The measured results, in good agreement with their simulated values, demonstrate that the Huygens dipole filtenna is electrically small (ka = 0.943) and low-profile (0.0385 λ0), together with enhanced out-of-band rejection performance characteristics. Its fractional bandwidth, broadside realized gain, front-to-back ratio, and overall efficiency values are, respectively, 1.16%, 2.33 dBi, 8.45 dB, and 63.1%.
Technological Approach to Mind Everywhere: An Experimentally-Grounded Framework for Understanding Diverse Bodies and Minds

Synthetic biology and bioengineering provide the opportunity to create novel embodied cognitive systems (otherwise known as minds) in a very wide variety of chimeric architectures combining evolved and designed material and software. These advances are disrupting familiar concepts in the philosophy of mind, and require new ways of thinking about and comparing truly diverse intelligences, whose composition and origin are not like any of the available natural model species. In this Perspective, I introduce TAME—Technological Approach to Mind Everywhere—a framework for understanding and manipulating cognition in unconventional substrates. TAME formalizes a non-binary (continuous), empirically-based approach to strongly embodied agency. TAME provides a natural way to think about animal sentience as an instance of collective intelligence of cell groups, arising from dynamics that manifest in similar ways in numerous other substrates. When applied to regenerating/developmental systems, TAME suggests a perspective on morphogenesis as an example of basal cognition. The deep symmetry between problem-solving in anatomical, physiological, transcriptional, and 3D (traditional behavioral) spaces drives specific hypotheses by which cognitive capacities can increase during evolution. An important medium exploited by evolution for joining active subunits into greater agents is developmental bioelectricity, implemented by pre-neural use of ion channels and gap junctions to scale up cell-level feedback loops into anatomical homeostasis. This architecture of multi-scale competency of biological systems has important implications for plasticity of bodies and minds, greatly potentiating evolvability. Considering classical and recent data from the perspectives of computational science, evolutionary biology, and basal cognition, reveals a rich research program with many implications for cognitive science, evolutionary biology, regenerative medicine, and artificial intelligence.
DEVELOPMENT OF A µBRDF GONIOSPECTROPHOTOMETER FOR BRDF MEASUREMENT ON TINY SURFACES

A µBRDF goniospectrophotometer has been developed at LNE-CNAM. This device performs traceable BRDF measurement with a measurement surface of 30 µm of diameter. All angular configuration of measurement belonging to the hemisphere are possible. The spectral range is the visible. This device intends to help to progress in the effort to extent the BRDF metrological scale from the centimetre size to micrometre size. Traceable µBRDF measurement are requested today to validate physical based rendering models used in virtual prototyping and to progress in the comprehension of the appearance of natural material like wool, wood, or leather.
Modulated Carrier Control for Single-Phase Active Power Filter

In this paper, an improved modulated carrier control for a single phase shunt active power filter(SAPF), which eliminates harmonic currents at the ac main drawn by nonlinear loads, is introduced. In contrast to conventional methods, since this control method does not need to generate a current reference for SAPF, only the ac main current is sensed instead of the load current and SAPF current. With the proposed control method, the ac main current is directly controlled to be sinusoidal and in phase with the supplied ac voltage by simply comparing the modulated carrier signal with the ac main current. The operation of the proposed SAPF is analyzed and simulation results verify its performance.
Coordination of steering and individual wheel braking actuated vehicle yaw stability control

Active safety of road transport requires, among other things, the improvement of road vehicle yaw stability by active control. One approach for yaw dynamics improvement is to use differential braking, thereby creating the moment that is necessary to counteract the undesired yaw motion. An alternative approach is to command additional steering angles to create the counteracting moment. The maximum benefit, of course, can be gained through coordinated and combined use of both methods of corrective yaw motion generation in a control strategy. This problem has been approached by using a revised model regulator here as the main controller that utilizes coordinated steering and individual wheel braking actuation, with the aim of achieving better vehicle yaw stability control. Independent use of the individual means of actuation are treated first. Possible strategies for combined and coordinated use of steering and individual wheel braking action in a vehicle yaw dynamics controller are then presented. Simulation results on a nonlinear two track vehicle model are used to illustrate the effectiveness of the coordinated approach.
Efficient Thinning Algorithm for Malaysian Car Plate Character Recognition

The thinning algorithm is one of the approaches of identifying each character printed on the car plate. Malaysian car plate characters appear in different character sizes, styles, customized printed characters etc. These variations contribute to difficulty in thinning successfully segmented and extracted license plate characters for recognition. To address these problems, an improved thinning operation for Malaysian car plate character recognition is proposed. In this algorithm, samples from segmented and extracted license plates are used for a thinning operation which is passed to Zhang-Suen thinning algorithm that could not guarantee one pixel thick and then to single pixelate algorithm that provides one pixel width of character for recognition. From the simulation, the result obtained has clearly proven to be the best for character recognition systems with least number of white pixels (777 pixels) and 0.26% redundant pixel left in the medial curve.
Comment on “Optimal exercise parameters of tai chi for balance performance in older adults: A meta‐analysis”

To the Editor: A recent study by Wang et al. searched the available databases and conducted a systematic review and meta-analysis to investigate the optimal parameters of a tai chi intervention to improve balance performance of older adults, which was published in the recent issue of Journal of the American Geriatrics Society. They came to the conclusion that “Tai chi is effective at improving the balance ability of adults over 60 years of age and a medium duration and high frequency of 24-form tai chi may be the optimal program for improving balance. ” Although the results are of great importance, we would like to underline some issues as to registration of the studies, quality assessment, and data analysis that we feel ought to be considered when interpreting these findings. First, there was no published protocol or registration for this study. Registering a meta-analysis protocol is important as it enables the promotion of transparency and avoidance of potential biases including both selection and selective outcome reporting biases. Second, the authors have clearly mentioned that “The methodological quality of included studies was assessed using the Physiotherapy Evidence Database (PEDro) scale” in the Methods section. However, the results of some evaluations may be inaccurate. For example, the studies of Lu et al. and Li et al. did not explain the specific methods of randomization. Furthermore, the Kappa score, which measures agreement between the reviewers, should also be provided in the article. Finally, according to the Cochrane Handbook for Systematic Reviews of Interventions 5.0, a high interstudy heterogeneity makes definitive conclusions hard to draw, thus high heterogeneity in the outcomes is our biggest concern. The authors attempted to explain the source of heterogeneity by adequate metaregression and subgroup analyses, but these did not guarantee that the outcomes were sufficiently stable. Compared with the random effects model used by the authors in the article, a model called inverse variance heterogeneity (IVhet) could have been used as an improved alternative to the random effects model. It was shown that the known issues of underestimation of the statistical error and spuriously overconfident estimates with the random effects model could be resolved by the use of an estimator under the fixed effect model assumption with a quasi-likelihood based variance structure. Therefore, we recommend using the IVhet model to re-analyze the outcomes in this meta-analysis. We respectfully appreciate that Wang et al. provided us with an important meta-analysis which can provide a guide for clinical decision-making. However, more studies with large sample size and good scientific design should be carried out to clarify this issue. We would welcome some comments by the authors as this would help us to further support the findings of this important clinical trial.
Interactive Infrastructures Distributed Interfaces for the Built Environment

An interactive infrastructure allows users to have access to the parameters of a building in real time, potentially leading to an increased productivity, lowering of energy and material consumption, and generally greater user satisfaction and experience. The aims of this research are to investigate and design new ways for interacting with the infrastructure of buildings, and to research and develop the basis for an interactive infrastructure communication language which enables the distributed elements of the infrastructure to communicate with each other and with the users. The effectiveness of infrastructure in buildings can be significantly improved with this approach.
Applications of the operator's model for controller design and optimization

Operator's models are attracting the interest of industry as they relate to monitoring and control complex large-scale processes. Modeling of the expert operator's experience is a perfect semiotic paradigm since the operator employs a variety of semea (atoms) or granules of information in order to establish an effect-cause relationship and take appropriate action in the event of an emergency. The operator plays a vital role in bringing the plant states back to a normal mode and takes advantage of mental behavioral models to predict future behavior patterns. The model presented captures the operator's and engineer's corrective actions that are based on their experience and their knowledge of the system's behavioral patterns. The operator's model is generic in nature and applicable to many complex industrial processes that require human intervention. It is tested first on the PID gain tuner and simulation results are presented; this is followed by an example from the mechatronics arena aimed at demonstrating the intelligent aspects of the proposed methodology.

Implementing Energy Efficiency & ESD from a Development Perspective

This note discusses the difficulties currently being experienced in implementing Ecological Sustainable Development (ESD) from a development perspective. It looks at what motivates developers and examines what is needed, either through mandatory measures or incentives to change the development culture in Australia. The note draws on experience from a number of current and recently completed projects and incorporates input from developers. It also includes discussion on the evolving outcomes of current industry initiatives aimed specifically at changing development processes and culture in Australia. The note focuses on new buildings. The way in which new buildings are financed and delivered generally differs significantly from retrofit projects being undertaken by building owners. Building owners can more easily factor long term operational costs of their buildings into their retrofit project financing. Typically, building developers are not the long-term owners, operators or tenants of the buildings that they deliver. Their projects are normally sold before or soon after completion to unrelated parties such as property trusts, superannuation funds, and other investors. It is this discontinuity in development and ownership of new buildings that creates perhaps the single biggest challenge to the uptake of ESD for the property industry.
Power Factor Correction Circuit with a Soft-switched Boost Scheme

In this paper, a new power factor correction circuit(PFC) based on a soft-switched boost scheme is proposed. Except for some soft-switching transition intervals, it operates exactly like the conventional boost scheme. Thus the desirable features of both high efficiency and easy control can be obtained. The design guidelines are suggested to achieve high efficiency. To verify the superior performance of the proposed circuit, experiment and simulation is carried out.
Factors Affecting Long-Term Compliance of CPAP Treatment—A Single Centre Experience

Continuous positive airway pressure (CPAP) has been the standard treatment of obstructive sleep apnoea/hypopnoea syndrome (OSA) for almost four decades. Though usually effective, this treatment suffers from poor long-term compliance. Therefore, the aim of our one centre retrospective study was to assess factors responsible for treatment failure and long-term compliance. Four hundred subsequent patients diagnosed with OSA and qualified for CPAP treatment were chosen from our database and compliance data were obtained from medical charts. Many differing factors kept patients from starting CPAP or led to termination of treatment. Overall, almost half of patients ended treatment during the mean time of observation of 3.5 years. Survival analysis revealed that 25% of patients failed at a median time of 38.2 months. From several demographic and clinical covariates in Cox’s hazard model, only the presence of a mild OSA, i.e., AHI (apnoea/hypopnoea index) below 15/h was a factor strongly associated with long term CPAP failure. The compliance results of our study are in line with numerous studies addressing this issue. Contrary to them, some demographic or clinical variables that we used in our survival model were not related to CPAP adherence.
Analysis and Design of a Gaussian Backscatter Antenna with Ring Focus Feed

This paper presents analysis and design of a Gaussian backscatter antenna with ring focus feed. The curvature of main re∞ector is Gaussian, and the subre∞ector is a portion of an ellipse. The antenna has axial symmetry. A backscattering technique is used with the main re∞ector to achieve wide beamwidth. The input parameters of the proposed antenna are derived in closed form. Physical theory of difiraction (PTD) is used to analyze the radiation pattern of the proposed antenna and verifled with experimental results. The efiects of the support structures on the radiation patterns of the proposed antenna have been investigated experimentally. The proposed antenna can produces high gain and wide beamwidth (coverage angle µ = §65 - ). This antenna can be used for realizing earth coverage beam in LEO satellite or indoor wireless LAN applications.
From Immediate Acceptance to Deferred Acceptance: Effects on School Admissions and Achievement in England

Countries and cities around the world increasingly rely on centralized systems to assign students to schools. Two algorithms, deferred acceptance (DA) and immediate acceptance (IA), are widespread. The latter is often criticized for harming disadvantaged families who fail to get access to popular schools. This paper investigates the effect of the national ban of the IA mechanism in England in 2008. Before the ban, 49 English local authorities used DA and 16 used IA. All IA local authorities switched to DA afterwards, giving rise to a cross-market differencein-differences research design. Our results show that the elimination of IA reduces measures of school quality for low-SES students more than high-SES students. After the ban, low-SES students attend schools with lower value-added and more disadvantaged and low-achieving peers. This effect is primarily driven by a decrease in low-SES admissions at selective schools. Our findings point to an unintended consequence of the IA to DA transition: by encouraging highSES parents to report their preferences truthfully, DA increases competition for top schools, which crowds out low-SES students.
