In a three-dimensional dissipative chaotic system circuit, by superimposing a cubic magnetron-type memristor and connecting a feedback circuit, a new four-dimensional synchronous controlling system is established. The control parameters have a significant impact on the system, and the system displays rich dynamic features such as hyperchaos, chaos, and period states. At the same time, the synchronization scheme for the chaotic system is designed based on the linear quadratic regulator (LQR), which effectively improves the system response speed and reduces the complexity of the synchronous controlling system. Further, numerical verification is carried out. Finally, a detailed verification of the chaotic system's dynamic characteristics is performed by hardware simulation. Simulation results and performance analysis show that the proposed method has synchronous controlling performance. Compared to some existing synchronous controlling schemes, this method is more widely applicable. [ABSTRACT FROM AUTHOR]

The main purpose of dredging is to maintain the required depth of harbors and marine and inland waterways. Any investment work in port infrastructure should be planned in such a way as to minimize interference with the port operations and vessel traffic. The research aims to analyze work scenarios involving a proposed dredging fleet using a Navi-Trainer Professional 5000 navigational and maneuvering simulator connected to the Transas Navi-Sailor 4000 navigation information system. An analysis performed using these electronic chart display and information system (ECDIS) simulators allows the operational parameters of the dredging project to be determined. These parameters include driving time, time taken to fill a TSHD dredger to full capacity, scale of maneuverability of the dredger within the port area, and determination of the safe distance between dredging vessels and other ships. The proposed solution may be supplemented with additional computer-based programs, providing a valuable tool in the research and monitoring of planned and current dredging projects.

Scientific data visualization is a critical aspect of fully understanding data patterns and trends. To date, the majority of data visualizations in nursing research – as with other biomedical fields – have been static. The availability of electronic scientific journal articles (which are quickly becoming the norm) has created new opportunities for dynamic and interactive data visualization which carry added cognitive benefits and support the ability to understand data more fully. Therefore, here we highlight the benefits of R, an open-source programming language, for scientific data visualization, with a specific focus on creating dynamic, interactive figures using the R shiny package. For R users, we have included a tutorial with example code to create three increasingly complex shiny applications. For individuals more interested in understanding the potential of R shiny as an innovative tool to interact with research data, we have included links to online versions of the examples that do not require any programming or R experience. We believe that widespread adoption of dynamic and interactive scientific data visualization will further support nurse scientists' higher-level mission of advancing our understanding of health and wellness of individuals and communities.

Recognizing the multifunctional capability of spinels, synthesis, and properties of oxide spinel with an equal concentration of Jahn Teller active Mn3+ and geometrically frustrated Cr3+ with non-magnetic Zn2+ have been explored. ZnCrMnO 4 , resulting from the room temperature oxidation reaction, has an average crystallite size of 16 nm. Nearly 25% of Zn occupies the octahedral sites along with Cr and Mn, as revealed by the successful structural refinement in the Fd-3m space group. Electron microscopic results confirm cubic spinel formation. Raman spectrum shows the disordered nature of the spinel. X-ray photoelectron spectral (XPS) analysis establishes mixed valences of manganese ((III), (IV)) and chromium ((III) and (VI)). ZnCrMnO 4 displays electronic transitions typical of Mn3+ and Cr3+ in its UV–Visible diffuse reflectance spectrum. Spin-glass frustration at 26 K, followed by an antiferromagnetic ordering at 10 K, is noticed for the sample from the magnetic measurements. The sample exhibits a surface area of 138 m2/g (BET measurements) and catalyzes the oxidation of aromatic alcohols (phenol, benzyl alcohol) and reduction of nitroaromatics efficiently.

Effective management of the electronic nautical charts (ENCs) preparation process using the electronic chart display and information system (ECDIS) is crucial to ensure the safety of ships. Delays or failures in this process can prevent the creation of a safe voyage plan and result in delays or maritime accidents, which may damage a company's reputation. To identify risk factors causing such issues, the quadratic mean method-based Fuzzy Analytical Hierarchy Process was used to weigh and determine the most prominent ones. Additionally, the study proposes specific solutions to eliminate each risk factor. The study's outputs are expected to improve the management of ENC preparation, which is a frequent task for ships using electronic navigation. [ABSTRACT FROM AUTHOR]

By working under the framework of the Helmholtz potential as a functional of the equilibrium density matrix, in this contribution, we provide theoretical evidence about a particular thermodynamic situation, where electronic species display their highest susceptibility to exchange electrons to or from surroundings. This situation is denominated as the electronic temperature condition. Neutral chemical species display their lowest possible hardness value at the electronic temperature condition, and remarkably, under this circumstance, the exchange of any amount of electronic charge will necessarily be translated into a net increase in the corresponding chemical hardness. Chemical response functions defined as partial derivatives of the Helmholtz potential with respect to the (average) number of electrons and evaluated at the electronic temperature condition provide comparable results than those obtained from the coarse quadratic approximation to the exact dependence of the electronic energy vs the number of electrons, including composite quantities as the electrophilicity index. In this context, we show that the exact Helmholtz potential dependence with respect to the number of electrons can accurately be approximated by "temperature dependent" polynomial fits (up to fourth order), evaluated at the electronic temperature condition.

In professional team sports, the collection and analysis of athlete-monitoring data are common practice, with the aim of assessing fatigue and subsequent adaptation responses, examining performance potential, and minimizing the risk of injury and/or illness. Athlete-monitoring systems should be underpinned by appropriate data analysis and interpretation, to enable the rapid reporting of simple and scientifically valid feedback. Using the correct scientific and statistical approaches can improve the confidence of decisions made from athlete-monitoring data. However, little research has discussed and proposed an outline of the process involved in the planning, development, analysis, and interpretation of athlete-monitoring systems. This review discusses a range of methods often employed to analyze athlete-monitoring data to facilitate and inform decision-making processes. There is a wide range of analytical methods and tools that practitioners may employ in athlete-monitoring systems, as well as several factors that should be considered when collecting these data, methods of determining meaningful changes, and various data-visualization approaches. Undeipinning a successful athlete-monitoring system is the ability of practitioners to communicate and present important information to coaches, ultimately resulting in enhanced athletic performance.

Graphene bilayers display peculiar electronic and mechanical characteristics associated with their two-dimensional character and relative disposition of the sheets. Here, we study nuclear quantum effects in graphene bilayers by using path-integral molecular dynamics simulations, which allow us to consider quantization of vibrational modes and study the effect of anharmonicity on physical variables. Finite-temperature properties are analyzed in the range from 12 to 2000 K. Our results for graphene bilayers are compared with those found for graphene monolayers and graphite. Nuclear quantum effects turn out to be appreciable in the layer area and interlayer distance at finite temperatures. Differences in the behavior of in-plane and real areas of the graphene sheets are discussed. The interlayer spacing has a zero-point expansion of 1.5 × 10−2 Å with respect to the classical minimum. The compressibility of graphene bilayers in the out-of-plane direction is found to be similar to that of graphite at low temperatures and increases faster as the temperature is raised. The low-temperature compressibility increases by 6% due to zero-point motion. Special emphasis is placed on atomic vibrations in the out-of-plane direction. Quantum effects are present in these vibrational modes, but classical thermal motion becomes dominant over quantum delocalization for large system size. The significance of anharmonicities in this atomic motion is estimated by comparing with a harmonic approximation for the vibrational modes in graphene bilayers. [ABSTRACT FROM AUTHOR]

A prototype inorganic material‐based solid‐state electrochromic device (ECD) using an active WO3 layer has been demonstrated followed by testing its potential application in blocking infrared (IR) radiation. A cost‐effective hydrothermal method has been used for fabricating WO3‐based electrodes. Prior to application, the structural and morphological characterization of the WO3 has been done using X‐ray diffraction, X‐ray photoelectron spectroscopy, and Raman spectroscopy. A solid‐state ECD has been fabricated in a sandwiched geometry with a supporting gel electrolyte. The solid‐state inorganic ECD displays a color contrast of more than 40% at 600 nm wavelength while toggling between transparent (OFF state) and blue (ON state) colors under a bias of as low as 2.5 V making it a power‐efficient device. The device is capable of maintaining its absorbance switching for longer than 2400 s without altering its absorbance rate. The device is capable of blocking IR radiation with more than 100% in its ON state as compared to its OFF state. A power‐efficient electrochromic performance has been reported from an inorganic‐alone solid state ECD while displaying its potential as an electronic curtain. [ABSTRACT FROM AUTHOR]

Traditional marine navigation methods are replaced by new solutions that use computers. Electronic Chart Display and Information Systems (ECDIS) are mandatory almost on every vessel [24],[25]. ECDIS not complying with regulations is an existing problem and a hazard for seafarers and the marine environment. But unfortunately, there is a deficit or even lack of procedures for checking whether ECDIS meets related performance standards. Regulatory bodies of the maritime industry are now contemplating how to tackle this blunder [1]. SOLAS regulations V/18 and V/19 [24], requires that in order to achieve chart carriage requirements (in terms of SOLAS Convention), the ECDIS equipment must conform to the relevant IMO performance standards. ECDIS units on board of the ships are required to comply with one of three performance standards (either IMO resolution A.817(19) [18], as amended [19],[20], or resolution MSC.232(82)) [21], or resolution MSC.530(106) [23], depending on the date of their installation. In this article, the author tries to explain the differences in these three documents. Along with technological progress, the equipment becomes more and more advanced and technologically sophisticated. This applies to both hardware, software and databases. ECDIS software developers should use the right tools, including incorporate automated self-tests into their products and shipping companies should employ maintenance strategies to improve ECDIS compliance [1], taking into account that time is running quickly.

Assessing innovative technologies and venture opportunities in the biopharma-life science space involves a complicated effort. However, should it be? This question is especially relevant when screening new opportunities. This paper addresses how established firms can quickly and efficiently assess new biomedicallife science ventures of different maturity (development and commercial) levels. Boni's (2012, 2019) "quick screen" and metaphorical "3 Ps" (project, product, platform) provide a practical framework to examine new biopharma-life science ventures (assets). Boni's works (2012, 2019) frame these elements. They intend to provide a framework to complement case studies for use separately in a workshop or "boot camp" format. Our present effort includes multiple case studies to provide practical guidance for the framework's use. Accordingly, this paper extends Boni's work by examining eight practical cases gathered via a purposeful sample to illustrate the use of the "quick screen" relative to each metaphorical category: project (4), product (2), and platform (2). Data sources included company and market information from company documents, firm websites, peer-review sources, market reports, and business portals. Data were mapped against "quick screen" criteria and categorized as positives, negatives, or uncertainties. Evaluation of the mapped data led to low to medium to high ratings relative to opportunity, monetary, and competitive advantage criteria. Descriptions provide qualitative insights to situate each case example relative to its specific "3 P" category, with six cases subclassified (e.g., moderatelow, low-moderate, high-moderate) when graded. This paper provides four practical contributions: 1) multiple "real world" cases to illustrate the framework, 2) a risk-opportunity-maturity relationship model, 3) scenarios of when or when not to use the "quick screen", and 4) engagement strategies based on "P" classification as practice contributions. It concludes that Boni's (2012, 2019) construct provides a useful and efficient tool for examining new biopharma-life science ventures (assets) at differing maturities. Future work should build on these case examples, findings, and contributions while embracing a more-structured case study evaluation methodology to further practice and theory contributions.

During a ship evacuation, many people panic as they do not know the direction that leads to the emergency muster station. Moreover, sometimes passengers get crowded in corridors or stairs, so they cannot save their lives. This paper proposes an IoT-enabled architecture for digital signage systems that directs passengers to the muster stations of a cruise ship by following the less dangerous route. Thus, crews' and passengers' safety risks during a ship evacuation can be low, and human health hazards may be limited. The system is based on a low-cost and open-source architecture that can also be used in a variety of fields in industrial IoT applications. The proposed modular digital signage architecture utilizes Light Emitting Diode (LED) strips that are remotely managed through a private Long-Term Evolution (LTE)/Fourth Generation (4G) cellular network. Publish–subscribe communication protocols were used for the control of the digital strips and particularly through a Message Queuing Telemetry Transport (MQTT) broker who publishes/subscribes every message to specific topics of the realized IoT platform, while the overall digital signage system centralization was implemented with an appropriate dashboard supported from an open-source RESTful API.

Display field communication (DFC) is a frequency-domain unobtrusive display-to-camera (D2C) communication, in which an electronic display serves as a transmitter and a camera serves as a receiver. In this paper, we propose a machine learning-based DFC scheme and evaluate its performance in a lab test scenario. First of all, we adopt the Discrete Cosine Transform (DCT) to transform a spatial-domain image into its spectral-domain equivalent. To reduce the computational complexity during the data-embedding process, addition allocation and subtraction data retrieval techniques are used. Moreover, channel coding is applied to overcome the data error caused by the optical wireless channel. In particular, robust turbo coding is used for error detection and correction. Afterward, we perform the experiments to validate the performance of the proposed system. After capturing the displayed image with a camera, data restoration is done using a deep learning technique. Extensive real-world experiments were performed considering various geometric distortions, noise, and different standard input images. As a result, we found that by increasing the transmit display image size (upsampling), the overall error rate can be reduced. In addition, real-world noise analysis is performed and it is notified that the actual noise is dominant in the low-frequency region of an image. The experimental results confirm the robust performance of the proposed DFC scheme and show that an error-free performance can be achieved up to a distance of 1 m in the given lab test environment setting.

The drill floor of an offshore drilling facility is equipped with a collision avoidance system to prevent collisions between moving equipment. In this paper, we present the visualization of the collision avoidance system using the digital twin concept. By classifying the core technologies of the digital twin, the elements necessary for the visualization of the collision avoidance system are derived, and the information for visualization is organized. We conduct 3D visualization of equipment and design IO devices necessary for the visualization. The movement of the floater is considered, and a database is built to efficiently search for the information required for the retrieval of stored 3D information. A collision detection situation is generated by operating the equipment using the input device required for simulation. Collision information is displayed as designed, and it is confirmed that the switching of the display between the present and past time is operating normally. The entire system functions normally as designed, including the input/output with other databases and equipment operation. Implementing a digital twin for an offshore platform is a time-consuming and costly process. It is expected that the improved anti-collision system can be expanded for the digital twin of an entire offshore platform. [ABSTRACT FROM AUTHOR]

Liquid crystals have numerous applications in various fields ranging from drug delivery, gene therapy in biosciences to electronic display and sensors in the field of opt-electronics and material science. In recent years, the properties of liquid crystals have been tailored by truncating the terminal atom(s) or group of atoms and/or by doping different types of nanomaterials; such as nanodots, nanorods, nanotubes, nanoplatelets, etc. Controlled assembly of nanoparticles in liquid crystal media can provide an alternative method to tailor new and desired opto-electronic properties in uniquely arranged quantum dots. This self-assembly of nanoparticles produces new hybrid (composite) materials having large number of applications. Here, we review different applications of nanoparticles and liquid crystal systems and highlight different approaches for achieving the hierarchical arrangement of nanoparticles in liquid crystal media. Here, phenomena like quantum dot self-assembly, formation of hollow microstructures, memory effect, and formation of microcapsules, etc. in presence of liquid crystal media are revisited and discussed critically. Band-gap-tailoring has emerged as a major thrust area because of numerous applications in making opto-electronic devices. Band-gap of liquid crystals can be also be tailored either by doping (metal) atoms or by nucleating their nano-clusters after removing their terminal groups. This phenomenon creates a lot of attraction among scientists. Hierarchical arrangement of nano-dots in liquid crystal media has gained a lot of interest, as they can possess special functional properties; many of which are known whereas many others need to be discovered. Hierarchical arrangement of nano-clusters can be obtained either by doping atoms into liquid crystals followed by a nucleation process or by forming molecular architectures by weak coupling between quantum dots because of van der Waal forces. Functional properties such as magnetic, physiochemical, and opto-electronic properties of the hybrid systems are different from their constituent parts, and thus the hybrid systems can find a vital role in the field of nanoscience and nanotechnology. Because of the aforesaid reasons, it has gained much attention in the last few decades. [ABSTRACT FROM AUTHOR]

Electronic holography is an ideal 3-D display technique to ameliorate the vergence-accommodation conflict, which is a possible cause of visual fatigue and discomfort from viewing conventional stereoscopic 3-D displays. Previous studies have measured accommodative and vergence responses to holographic images and to real objects, and the results showed that these responses are in good agreement. To demonstrate the effectiveness of electronic holography as a possible solution to the vergence-accommodation conflict caused by viewing conventional stereoscopic 3-D displays, we measured both accommodative and vergence responses to reconstructed images of holograms and super multiview holographic stereograms. We also measured responses to real objects located at various distances and conventional two-view stereo images for comparison. The results indicate that the accommodative responses to the electro-holographic display and super multiview holographic stereogram change with the vergence response in a similar manner, as is the case with real objects as compared to conventional two-view stereo display. This suggests that the electronic holographic display and super multiview holographic stereograms are promising candidates for resolving the vergence-accommodation conflict. [ABSTRACT FROM AUTHOR]

There is an undeniable recognition that maritime cybersecurity risk management should involve process, technology, and people. However, thus far, most studies have focused on the technical and process aspects of maritime cybersecurity, more than on the human element. On a vessel, the Electronic Chart Display and Information System (ECDIS) is, amongst all the electronic devices on the bridge, a complex and indispensable maritime sociotechnical system that must consider both technical and human aspects. In the context of maritime cyber resilience, it is important to note that when developing strategies for maritime cybersecurity, one cannot only consider technical security measures and ignore human error, as this does not adhere to good cybersecurity practice. To address this, this study aims to identify the navigating officers' responsibilities for ECDIS cybersecurity and find the human error probabilities during these tasks via the SLIM-based human reliability analysis method. The outputs of this study provide an insight for industrial policies and best practices, in ECDIS cybersecurity risk management in terms of the behavioural and cultural aspects of shipping.

With the development of video technology, a large amount of video data generated from video conferences, sports events, live broadcasts and network classes flows into our daily lives. However, ultra-high-definition video transmission is still a challenge due to the limited network bandwidth and instability, which further affects the quality of video service closely linked with consumer electronic video display. To address this challenge, we propose a deep-learned perceptual quality control approach, which can significantly improve the video quality and visual experience at the same bandwidth. The proposed scheme mainly involves saliency region extraction, perceptual-based bits allocation, and video enhancement. Firstly, we exploit a multi-scale deep convolutional network module to predict the static saliency map that semantically highlights the salient regions. Secondly, we develop a recurrent neural network model to extract the dynamic saliency regions. Finally, a three-level rate allocation scheme is developed based on the resulted saliency guidance, which is more reasonable by taking into account the visual characteristics of human eyes. Experimental results on a large dataset show that our method achieves an average gain of 1.5dB on the salient regions without introducing an extra bandwidth burden, which significantly improves the visual experience and paves the way to intelligent video communication.

Most hospitals and clinics utilize commercial grade displays for viewing wrist radiographs. There is no evidence regarding the role of the imaging display used to evaluate the radiographs. The aim of this study was to compare the rates of scaphoid fracture diagnosis by commercial grade and medical grade displays. Wrist radiographs of patients that had clinical signs of scaphoid fracture without findings on plain radiography (suspected scaphoid fractures) were retrospectively collected from ER department and interpreted for radiographic signs of fracture by four orthopedics seniors commercial grade and medical grade displays. The difference in fracture diagnosis rates were studied. Inter- and intra-observer variability were also studied. Study population comprised of 175 high quality wrist radiographs were interpreted. Mean 48.25 (27%) scaphoid fractures were observed on commercial grade display compared to 66 (38.2%) on medical grade display (p = 0.076). The total inter-observer agreement could be defined as a moderate agreement (κ = 0.527, Accuracy = 0.77). Total agreement between all observers were observed in 86 (49.1%) cases compared to 89 (50.9%) cases when reviewing X-rays on commercial and medical displays, respectively. The scaphoid fracture detection rate on medical grade display was not statistically higher compared to non-medical grade displays, but we did find a tendency toward medical grade display. We found that in a substantial number of cases, our observers recognize signs of fracture that were initially evaluated as "suspected fracture" by the ER physicians. As a pilot study, we found evidence that support the need for a prospective study designed to compare the observations to a gold standard modality, such as MRI. We believe utilizing medical grade displays can increase the rate of diagnosis in cases of clinically suspected scaphoid fractures and better manage the clinical scenario of a suspected scaphoid fracture.

Display-to-camera (D2C) communications has emerged as a key method for next-generation videos that offer side information to camera-equipped devices during normal viewing. This paper presents Deep learning-driven Complementary Color Barcode-based Optical Camera Communications (DeepCCB-OCC), a D2C system using multiple deep neural networks built for imperceptible transmission and reliable communication in a D2C link. DeepCCB-OCC takes advantage of a the You Only Look Once (YOLO) model to provide seamless detection of a color barcode area in electronic displays. To identify transmitted color barcode symbols in the received image, we define various color barcode patterns caused by the synchronization jitter between the camera and the display. Then, DeepCCB-OCC incorporates convolutional neural network (CNN) models to accurately detect the pilot and data symbols in the transmission packets, regardless of the various D2C environments. Experiments with a commercial monitor and a smartphone demonstrate that DeepCCB-OCC outperforms the conventional CCB-OCC system from various distances and angles of a D2C link. The experiment results prove that, when the alignment angle was 20 degrees at a distance of 90 cm between the display and the camera, the proposed scheme achieved approximately 79.1 bps, which showed a performance improvement of 14.1% compared to the existing technique.

Computational linguistics is concerned with understanding language from a computational perspective and constructing artifacts that are useful in processing and generating language. In the use of language, whether human language or programming language, there can be an error that makes the language not understood properly. One of the errors that often occurs is syntax error. In language, a syntax error is a mistake in using a language that involves organizing words and phrases that do not make sense. While in programming, a syntax error is an error in writing code in a program that makes the format or information unrecognizable by the computer system. Such errors are the simplest of errors but can affect many aspects of the final code output. This article aims to show how writing errors or typos in programming code can affect some or all of the results. The data obtained is data from web programming code that is used to make the website display the Geographic Information System Clustering the Distribution of Stunting Disease in Banggai Regency with K-Means, and also the R programming code used to calculate the stunting distribution using K-Means. The results of this article will show that a typo, even just a letter or any single punctuation, can affect the program's final result. [ABSTRACT FROM AUTHOR]

Across three experiments (N = 1565), we investigated how forecasts about the spread of COVID 19 are impacted by data trends, and whether patterns of misestimation predict adherence to social-distancing guidelines. We also investigated how mode of data presentation influences forecasting of future cases by showing participants data on the number of COVID-19 cases from a 5-week period in either graphical, tabular, or text-only form. We consistently found that people shown tables produced more accurate forecasts compared to people shown line-graphs of the same data; yet people shown line-graphs were more confident in their estimates. These findings suggest that graphs engender false-confidence in the accuracy of forecasts, that people's forecasts of future cases have important implications for their attitudes concerning social distancing, and that tables may be better than graphs for informing the public about the trajectory of COVID-19.

As a representative of the new reflective display technology, electrowetting display (EWD) technology can be used as a video playback display device due to its fast response characteristics. Direct current (DC) driving brings excellent reflectivity, but static images cannot be displayed continually due to charge trapping, and it can cause afterimages when playing a dynamic video due to contact angle hysteresis. Alternating current (AC) driving brings a good dynamic video refresh ability to EWDs, but that can cause flickers. In this paper, a dynamic adaptive display model based on thin film transistor-electrowetting display (TFT-EWD) was proposed. According to the displayed image content, the TFT-EWD display driver was dynamically adjusted by AC and DC driving models. A DC hybrid driving model was suitable for static image display, which could effectively suppress oil backflow and achieve static image display while ensuring high reflectivity. A source data non-polarized model (SNPM) is an AC driving model which was suitable for dynamic video display and was proposed at the same time. Compared with DC driving, it could obtain smooth display performance with a loss of about 10 absorbance units (A.U.) of reflective luminance, which could solve the flicker problem. With the DC hybrid driving model, the ability to continuously display static images could be obtained with a loss of 2 (A.U.) of luminance. Under the AC driving in SNPM, the reflected luminance was as high as 67 A.U., which was 8 A.U. higher than the source data polarized model (SPM), and it was closer to the reflected luminance under DC driving.

In this paper, the test of residual DC voltage was carried out on the test cells with different combinations of liquid crystal (LC), polyimide alignment film (PI) and color resist flat layer (PFA). Combined with the circuit simulation results, the residual DC voltage was comprehensively analyzed, it is its characteristics of "fast accumulation" and "slow release" that lead to the decrease in the reliability of TFT‐LCD display. By analyzing the characteristic parameters of related materials, we have given the optimal combination of materials to reduce the residual DC voltage. As various application scenarios require higher and higher panel performance and their material combinations become more and more complex, the research results in this article will be of great significance for improving the reliability of TFT‐LCD displays.

This paper presents the findings of an environmental scan conducted as part of a Digital Exhibits Intern Librarian Project at the Edmonton Public Library in 2016. As part of the Library's 2016-2018 Business Plan objective to define the vision for a digital exhibits service, this research project aimed to understand the current landscape of digital displays in learning institutions globally. The resulting study consisted of 39 structured interviews with libraries, museums, galleries, schools, and creative design studios. The environmental scan explored the technical infrastructure of digital displays, their user groups, various uses for the technologies within organizational contexts, the content sources, scheduling models, and resourcing needs for this emergent service. Additionally, broader themes surrounding challenges and successes were also included in the study. Despite the variety of approaches taken among learning institutions in supporting digital displays, the majority of organizations have expressed a high degree of satisfaction with these technologies.

Imaging image acquisition and display has always been an important application field of visual communication art. A good imaging acquisition and display system can give the audience an excellent visual experience. However, conventional imaging image acquisition equipment is too bulky and expensive. At the same time, the existing imaging acquisition technology is generally only suitable for two-dimensional plane design. It is difficult to construct the three-dimensional and realistic sense of actual objects, which makes the development of the entire imaging system slow. Existing imaging acquisition technologies have difficulty keeping pace with the technological age. In this paper, according to the actual needs, a three-dimensional imaging technology was proposed to improve the efficiency of imaging image acquisition. And the principle of imaging information display was used to enhance the visual communication effect. Then, at the algorithm level, virtual reality technology was combined with convolutional neural network-related algorithms to improve the overall accuracy of the algorithm and control the error well. The experimental results showed that the optimized VR technology leads the whole stage in terms of mean square error. Among them, after testing 400 samples in the two experiments, the error performance is controlled below 0.32, and the best error control performance is 0.07; the unoptimized virtual reality technology error control is not ideal. The minimum error failed to break below 0.2, and the optimized algorithm had a high accuracy of 99.3%, which greatly improved the feasibility of the imaging information acquisition and display system.

The arrival of the digital information age has realized the transformation of people's production and lifestyle, which has also promoted the vigorous development of the art field. At present, the application of informatization in oil painting techniques is increasing. The purpose of this paper is to realize the research on the visual planarization of oil painting techniques in the digital information environment to promote the ecological development of the computer and art field. By using the advanced methods and technologies of its information display, this paper proposed the use of image processing algorithms in the digital information age to guide the integration of digital information technology and oil painting techniques. This helped to analyze and solve objective problems such as the profound meaning of the objective existence in the art field and the inability to understand the emotion in it. It can be seen from the analysis of the oil painting color model that, in the RGB model, when the wavelength is within a certain range, it can be used. But when the wavelength is between 444 nanometers and 526 nanometers, the red intensity is too low. That is to say, it can not effectively express its corresponding color in this wavelength range. This model is very challenging. In the XYZ color model, when the wavelength is in a certain region, the output of red light becomes a value less than 0. Any color in this space can be well represented by a linear combination of X, Y, and Z. Therefore, the study of visual flattening of oil painting is very important in the field of art.

Iris presentation attack detection (PAD) is still an unsolved problem mainly due to the various spoof attack strategies and poor generalisation on unseen attackers. In this paper, the merits of both light field (LF) imaging and deep learning (DL) are leveraged to combine 2D texture and 3D geometry features for iris liveness detection. By exploring off‐the‐shelf deep features of planar‐oriented and sequence‐oriented deep neural networks (DNNs) on the rendered focal stack, the proposed framework excavates the differences in 3D geometric structure and 2D spatial texture between bona fide and spoofing irises captured by LF cameras. A group of pre‐trained DL models are adopted as feature extractor and the parameters of SVM classifiers are optimised on a limited number of samples. Moreover, two‐branch feature fusion further strengthens the framework's robustness and reliability against severe motion blur, noise, and other degradation factors. The results of comparative experiments indicate that variants of the proposed framework significantly surpass the PAD methods that take 2D planar images or LF focal stack as input, even recent state‐of‐the‐art (SOTA) methods fined‐tuned on the adopted database. Presentation attacks, including printed papers, printed photos, and electronic displays, can be accurately detected without fine‐tuning a bulky CNN. In addition, ablation studies validate the effectiveness of fusing geometric structure and spatial texture features. The results of multi‐class attack detection experiments also verify the good generalisation ability of the proposed framework on unseen presentation attacks. [ABSTRACT FROM AUTHOR]

[Display omitted] Electrowetting-on-dielectric (EWOD) phenomenon is widely employed for liquid actuation at the micro scale. Due to its simple structure, low cost, low power consumption and fast response speed, diverse applications are developed and commercialized based on EWOD, such as digital microfluidics, tunable lenses, electronic displays, small-scale propellers etc. However, the liquid actuation with EWOD requires a high-voltage but low-current power source. The accessory equipment (e.g., waveform generator and amplifier) not only attenuates the benefits originated from microscale liquid actuation, but also limits its portability, wearability, and environmental friendliness of the EWOD inspired applications. Triboelectric nanogenerator (TENG) is a promising technology to convert arbitrary mechanical energy to electricity based on triboelectrification and electrostatic induction. The output electric signal shows a high-voltage but low-current property which well matches the demands in EWOD devices. This paper reviews the technical advances in the TENG powered EWOD devices developed in recent years. The mechanisms, structures, and performance of each application are reviewed. The challenges and future perspectives are put forward. The review and discussion in this study open up opportunities for the development of TENG and EWOD based self-powered liquid actuators.

E-navigation provides the opportunity to apply modern digital and other electronic enhancements to improve the safety and efficiency of maritime navigation. Under the broad banner of e-navigation, the International Hydrographic Organization's S-100 product specification framework is facilitating the establishment of a standard maritime data structure to enable a free-flowing exchange of navigation information between ships, ship-to-shore and shore-to-ship. There are currently over 30 S-100 based product specifications at various stages of development. For the data standard to be properly used, navigation software products must be capable of reading as well as comprehending the data format and content. To develop robust and stable software, the S-100 data models and product specifications must be consistent, accurate and interoperable in conveying various types of information. This paper describes the results of research on S-100 based product specifications from the viewpoint of developing maritime navigation software. In particular, issues related to software development for Electronic Chart Display Information System (ECDIS) and Vessel Traffic Service (VTS) are discussed, including appropriate data model analysis, processing of features, and symbols overlapping with other product specifications. Proposed solutions for some identified issues are presented. [ABSTRACT FROM AUTHOR]

Regarding the constantly increasing cooling demands in the building sector due to climate change effects, strategies for reducing the cooling demands are vital. Among the major strategies is thermal insulation, however, overheating phenomenon during the summer months is a frequent problem in over-insulated buildings. In this study, a typical dwelling was examined in ten Mediterranean regions concerning the influence of the envelope's thermal transmittance on its cooling performance. A passive dynamic insulation system was also developed and implemented, while its cooling performance was optimized through a rule-based control strategy for the cooling period of each region. Regarding always the occupants' thermal comfort perception, increased cooling loads were recorded for most of the regions with the highly insulated envelope, which reached up to 12% for the city of Damascus, while in the hot-desert regions the picture is reversed. The dynamic insulation system displayed great potential, as its efficiency was maximum with the super-insulated envelope, resulting in up to 61% less cooling demands for the city of Seville. Finally, by disregarding the occupants' interference in the cooling system, as most of the national legislations do, higher cooling needs are calculated, that in our study reached up to 49% for the super-insulated envelope.

Four examples of para-nitro substituted 2-(arylimino)pyridine-nickel(II) bromide complexes of general formula, [2-{(2,6-R-4-NO2C6H2)N=CMe}C5H4N]NiBr2, but differentiable by the steric/electronic properties displayed by the ortho-groups [R = i-Pr (Ni1), Et (Ni2), CHPh2 (Ni3), CH(4-FPh)2 (Ni4)], have been prepared in good yield. For comparative purposes, the meta-nitro complex, [2-{(2,6-i-Pr2-3-NO2-4-(4-FPh)2C6H)N=CMe}C5H4N]NiBr2 (Ni5), has also been synthesized. The molecular structures of mononuclear Ni3·xH2O (x = 2, 3) and bromide-bridged dinuclear Ni4 and Ni5 are disclosed. Upon activation with either ethylaluminum dichloride (EtAlCl2) or modified methylaluminoxane (MMAO), all precatalysts displayed good catalytic performance at operating temperatures between 30 °C and 60 °C with higher activities generally seen using EtAlCl2 [up to 4.7 × 106 g PE (mol of Ni)−1 h−1]: Ni2 ~ Ni5 > Ni1 ~ Ni4 > Ni3. In terms of the resultant polyethylene (PE), Ni4/EtAlCl2 formed the highest molecular weight of the series (Mw up to 1.4 × 105 g mol−1) with dispersities (Mw/Mn) ranging from narrow to broad (Mw/Mn range: 2.2–24.4). Moreover, the melting temperatures (Tm) of the polymers generated via EtAlCl2 activation fell in a narrow range, 117.8–126.0 °C, which resembles that seen for industrial-grade linear-low density polyethylene (LLDPE). Indeed, their 13C NMR spectra revealed significant amounts of uniformly distributed long-chain branches (LCBs), while internal vinylene groups constituted the major type of chain unsaturation [vinylene:vinyl = 5.3:1 (EtAlCl2) and 9.9:1 (MMAO)].

Visual inspection is the traditional method behavior analysts use to interpret functional‐analysis results. Limitations of visual inspection include lack of standardized rules, subjectivity, and inconsistent interrater reliability (Fisch, 1998). To address these limitations, researchers have developed, evaluated, and refined structured criteria to aid interpretation of functional analyses of destructive behavior (Hagopian et al., 1997; Roane et al., 2013; Saini et al., 2018). The current study applied the structured criteria Saini et al. (2018) described to functional analyses of inappropriate mealtime behavior. We assessed its predictive validity and evaluated its efficiency relative to 3 post hoc visual inspection procedures. Validity metrics were lower than those in Saini et al. however, ongoing visual inspection increased the efficiency of functional analyses by more than 30%. We discuss these findings relative to the procedural differences between functional analyses of destructive behavior and inappropriate mealtime behavior. [ABSTRACT FROM AUTHOR]

In the course of developing the publication "Recommendations on usage of ECDIS and preventing incidents" [19] by members of the Oil Companies International Marine Forum (OCIMF), they have identified the importance of sharing information on a malfunction of an ECDIS. The problem was discussed in the forum of the International Maritime Organization (IMO). As a consequence, there was a necessity to modify the IMO's ECDIS -- Guidance for Good Practice. This guidance is intended to assist smooth implementation of ECDIS and its ongoing safe and effective use on board ships. In the new version of this document (second revision), new important terms appear, such as: type approval authority (TAA), type approval certificate (TAC), letter of acceptance (LOA), declaration of conformity (DOC). In this article, the author tries to present the problem and describe the actions taken by the appropriate IMO bodies. [ABSTRACT FROM AUTHOR]

The article discusses research which focused on the development of a gated and cascaded temporal RNA transcription process. Topics explored include the activation of transcription scaffolds due to the presence of RNA polymerase (RNAP) aptamer strand and ribonucleoside triphosphates, the transient RNA synthesis following the application of the aptamer-RNAP autoinhibiting complex, and observations of the temporal transcription of transient ribozymes.

Organic light-emitting diode (OLED) fibers with favorable electroluminescence properties and interconnectable pixel configurations have represented the potential for wearable electronic textile displays. Nevertheless, the current technology of OLED fiber-based textile displays still leaves to be desired due to several challenges, including limited emission area and lack of encapsulation systems. Here we present a fibrous OLED textile display that can attain a large emission area and long-term stability by implementing addressable networks comprised of integrated phosphorescence OLED fibers and by designing multilayer encapsulations. The integrated fiber configuration offers decoupled functional fiber surfaces for an interconnectable 1-dimensional OLED pixel array and a data-addressing conductor. Tailored triadic metal/ultrathin oxide/polymer multilayer enables not only the oxygen/water permeation inhibition but also the controllable conductive channels of dielectric antifuses. Together with reliable bending stability, the long-term operation of OLED textiles in water manifests the feasibility of the present device concept toward water-resistant full-emitting-area fibrous textile displays.

Purpose: Drug shortages are anticipated to worsen with time as the Coronavirus Disease 2019 (COVID-19) pandemic continues. The aim of this study is to track drug shortages within Illinois and identify causes and trends to this time-sensitive problem. Methods: In order to communicate between health systems within the state, the Illinois Council of Health-System Pharmacists (ICHP) developed a medication shortage dashboard, which collects information from health systems in the state on current drug shortages. Classes of medications inquired about included: anti-infectives, neuromuscular blocking agents (NMBAs), sedatives/analgesics, vasopressors, and "others." Data was gathered from 6 different medication shortage dashboards, ranging from May 20, 2020 to June 22, 2020 and was used to track drug shortages within Illinois. Additionally, this data was analyzed in conjunction with the number of hospital beds utilized by COVID-19 patients at the time. Results: Illinois's medication shortage dashboard tracked the supply level of 42 medications used in the treatment of patient's hospitalized with COVID-19. Data from an average of 75 health systems was analyzed each week (average response rate: 52%). For each medication, health systems identified if they had ample supply, mild shortage, moderate shortage, or critical shortage. Overall the trends of these medications positively correlated with the number of hospital beds utilized by COVID-19 patients in Illinois (r 2 = 0.7). Conclusion: The data from this study supports the conclusion that increased hospital bed utilization by COVID-19 patients is correlated with increased drug shortages of medications used in the treatment of COVID-19. It is imperative that health systems take appropriate action to prevent and manage drug shortages. [ABSTRACT FROM AUTHOR]

Data visualization techniques are useful for examining large multidimensional data sets. In this exploratory data analysis (EDA) study, we applied a visualization pattern detection and testing process to deidentified data to discover patterns in whole‐person health for adults 65 and older. Whole‐person health examines a person's environmental, psychosocial, and physical health, as well as their health‐related behaviors; and assesses their strengths, challenges, and needs. Strengths are defined as assets and capabilities in the face of short‐or long‐term stressors. We collected data using a mobile application that delivers a comprehensive whole‐person assessment using a simplified version of a standardized instrument, the Omaha System. The visualization pattern detection process is iterative, includes various techniques, and requires visualization literacy. The data visualization techniques applied in this analysis included bubble charts, parallel coordinates line graphs, box plots, and alluvial flow diagrams. We discovered six patterns within the visualizations. We formulated and tested six hypotheses based on these six patterns, and all six hypotheses were supported. Adults 65 and older had more strengths than challenges and more challenges than needs (p < 0.001). Strengths and challenges were negatively correlated (p < 0.001). Unexpectedly, a subset of adults 65 and older who had many, but not all, strengths had significantly more needs (p = 0.04). The use of standardized terminology with its inherent data interrelationships was key to discovering patterns in whole‐person health. This methodology may be used in future EDA research using new data sets. [ABSTRACT FROM AUTHOR]

The emergency department (ED) is at the forefront of medical care, and the medical team needs to make outright judgments and treatment decisions under time constraints. Thus, knowing how to make personalized and precise predictions is a very challenging task. With the advancement of artificial intelligence (AI) technology, Chi Mei Medical Center (CMMC) adopted AI, the Internet of Things (IoT), and interaction technologies to establish diverse prognosis prediction models for eight diseases based on the ED electronic medical records of three branch hospitals. CMMC integrated these predictive models to form a digital AI dashboard, showing the risk status of all ED patients diagnosed with any of these eight diseases. This study first explored the methodology of CMMC's AI development and proposed a four-tier AI dashboard architecture for ED implementation. The AI dashboard's ease of use, usefulness, and acceptance was also strongly affirmed by the ED medical staff. The ED AI dashboard is an effective tool in the implementation of real-time risk monitoring of patients in the ED and could improve the quality of care as a part of best practice. Based on the results of this study, it is suggested that healthcare institutions thoughtfully consider tailoring their ED dashboard designs to adapt to their unique workflows and environments.
