Directions of the 100 most cited chatbot-related human behavior research: A review of academic publications (2021)

Chatbots are becoming a common trend in the service industry, education, and daily life. Increasing evidence has shown that chatbots have the potential to change the way people learn and search for information in human behavior. However, a systematic review of chatbot-related human behavior research with high citation rates has not been performed. Papers with high citation rates represent the latest changes in a particular research field, and reflect the current issues or research trends. By reading highly cited papers, researchers can identify important research questions. Therefore, this article presents a systematic literature review exploring the latest changes in chatbot research, and reviews the top 100 highly cited articles. The review shows that the highly cited chatbot-related studies have proposed new conversation strategies and compared different modes of human–human online conversations and human–chatbot conversations to find more effective methods of online communication. In addition, existing research has focused on high-level statistical performance and system development and testing. The findings also show that chatbots have started to be applied to the field of education, and there is much potential for the use of chatbots to improve the learning process and learning outcomes.

High sensitivity gas sensor based on high-Q suspended polymer photonic crystal nanocavity (2014)

We present high-sensitivity, multi-use optical gas sensors based on a one-dimensional photonic crystal cavity. These devices are implemented in versatile, flexible polymer materials which swell when in contact with a target gas, causing a measurable cavity length change. This change causes a shift in the cavity resonance, allowing precision measurements of gas concentration. We demonstrate suspended polymer nanocavity sensors and the recovery of sensors after the removal of stimulant gas from the system. With a measured quality factor exceeding 104, we show measurements of gas concentration as low as 600 parts per million (ppm) and an experimental sensitivity of 10 ppm; furthermore, we predict detection levels in the parts-per-billion range for a variety of gases.
C2-O-02Dimorphic secretory vesicles produced from the Golgi stacks of mucilage secreting root cap cells (2015)

Non-cellulosic cell wall polysaccharides are synthesized in the Golgi and packaged in secretory vesicles (SVs) that are targeted to the plasma membrane (PM). Golgi stacks in mucilage-secreting root cap cells produce large amounts of polysaccharides and the ultrastructure of the root cap Golgi stacks exhibit signs of massive biosynthesis. In this study, we examined Golgi stacks and TGN compartments in the root cap cells of alfalfa and Arabidopsis with electron tomography. The TGN compartments of root cap cells usually consist of one large SV (LSV) and numerous small SVs (SSVs) that are connected by tubules. Diameters of the SSVs range from 50 nm to 100 nm, equivalent to those of meristem cell SVs [ 1 ]. The average size of LSVs measured 218.54 nm, significantly larger than diameters of SSVs. In root cap cells of pikb1/pikb2 double mutant plants, SVs of sizes intermediate between LSVs and SSVs appeared. This disappearance of the distinction between LSV and SSV indicates that the RabA4b-PIKb complex is required for the normal production of SVs in the root cap cells. The COPII, COPIa, and COPIb-type vesicles were identified in the ER export site, cis-Golgi, and medial/trans-Golgi, respectively, in the root cap cells. The onset of pectin biosynthesis begins from the medial Golgi cisternae of which rims begin to swell. The swellings of adjacent cisternae often crammed on one side of the stack instead of forming a spiral arrangement. These swellings separate from the medial- and trans-Golgi to become sausage-shaped vesicles. Our results illustrate the structural plasticity of the plant Golgi stack in response to changes in their biosynthetic activities. It also shows that the basic features such as types of Golgi vesicles and assembly of new cisternae prior to activation of biosynthesis are conserved in the usual Golgi stacks of the root cap cells.
METHOD FOR EFFICIENT REPRESENTATION OF THE INFORMATION ON THE WEIGHTING COEFFICIENTS OF A TRANSMITTING BEAMFORMER IN WIRELESS DIGITAL COMMUNICATION SYSTEMS WITH MULTIELEMENT ADAPTIVE ANTENNAS A. A. Mal'tsev, ∗ S. A. Tiraspol'sky, and (2008)

We consider the problem of transmission of channel state information for a transmitting beamformer in digital communication systems with adaptive transmitting and receiving antennas. It is shown that using the unitary property of the weighting matrices of the transmitting beamformer, we can significantly reduce the amount of transmitted information with the help of the wellknown Givens decomposition. We propose a method for determining the optimal bit allocation for quantization of the complex weighting coefficients of the transmitting beamformer. Results of mathematical simulation of a wireless digital communication system with multielement adaptive antenna arrays are shown for a multipath Rayleigh channel.
PrxBa1-xCoO3Oxide Electrodes for Oxygen Evolution Reaction in Alkaline Solutions by Chemical Solution Deposition (2015)

Perovskite PrxBa1-xCoO3 (PBCO) thin film electrodes were used in a water splitting electrolysis cell for oxygen evolution reaction (OER) and studied by cyclic voltammetry. We systematically varied the composition of the PBCO deposited by spin-coating using different Ba to Pr ratios. The influence of Pr-content in the perovskite on catalytic OER activity is discussed for two different substrates, namely platinized Si and laser polished Ti. The crystallographic structure of the thin films and the oxidation state of the metal ions in the perovskite is examined by XRD and X-ray photoelectron spectroscopy, respectively. In addition, we propose a laser-polishing process of the Ti substrates as alternative to the classical surface treatment, providing smooth and homogeneous surfaces. Accelerated life time tests have shown the advantage of the catalytically active films deposited on laser polished Ti substrates.
On Using the Agenda to Influence Group Decisions: Theory, Experiments, and an Application (1975)

Three general claims are made in the paper. First, the agenda or groupings in which alternatives are considered for adoption or elimination is a major parameter in determining what a group will choose. Secondly, the nature of this influence is sufficiently systematic to yield to an analytical model. Finally, it is claimed that this discovery has important practical implications. In support of these claims, the paper offers a theory of the basis of the influence together with an attempt to capture this theory within a mathematical model. The results of an application of the theory to a real situation and the results of several series of experiments are reported.
Lens regeneration in juvenile and adult rabbits measured by image analysis. (1992)

Secondary cataract growth commonly occurs after extracapsular cataract extraction. The proliferation of this regrowth occurs at rates related to many factors. In this study, the authors analyzed the amount of lens regeneration after endocapsular lens extraction that leaves the anterior and posterior capsules relatively intact. The analysis was performed in New Zealand albino rabbits with the aid of image analysis measurements in young and adult animals. The effect of low vacuum suction of the anterior capsule on the growth was determined. Lens regeneration was used as a measure of the growth potential of the leftover epithelial cells in the capsule bag. The results showed that lens regeneration was significantly faster in younger rabbits. However, low vacuum suction had no effect on the growth rate. Potential therapeutic agents for preventing secondary cataracts may be better analyzed with image analysis processing of lens regeneration, a precise and rapid measurement technique.
Field-oriented control of an induction machine in the field-weakening region with DC-link and load disturbance rejection (1997)

A method of actively maintaining voltage margin in field-oriented induction machine controllers is proposed. A voltage-margin controller is developed that rejects DC-link and load disturbances, such that current regulation and field orientation is maintained. In addition, the voltage-margin controller coupled with rotor-flux-oriented control is shown to provide maximum torque capability equivalent to stator-flux-oriented control.
RGB Color Patterning for AMOLED TVs (2013)

RGB color patterning is one of the key technologies for manufacturing large‐sized AMOLED TVs. Two competing approaches are currently being used to realize RGB subpixels. One requires a more difficult manufacturing process but has better color purity; the other is easier to manufacture but requires optimization in algorithms to overcome some weaknesses.

Inflow Cannula Pressure Sensor for Autonomous Dynamic Ventricular Assist Device Control (2022)

Background: Through significant technological improvement and shortage of donor organs, ventricular assist devices (VAD) have become an important part of end-stage heart failure treatment. However, VADs are still associated with adverse effects, such as congestion or ventricular wall collapse. These adverse effects are the result of the inability of current generation VADs to dynamically adapt the pumping power to the real time perfusion needs of the human body.
Robust temperature control of thermostatic oven based on adaptive and fuzzy algorithm (2003)

The authors propose a simple robust temperature control system for a thermostatic oven based on a fuzzy I-P controller and a fuzzy passive adaptive compensator. The proposed control algorithm suppresses the state error caused by dynamics variation, disturbances, and dead time. Numerical results that confirm the validity of the proposed robust temperature control of a thermostatic oven are presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Moisture effects on mechanical behavior of CNF-RGO nanocomposites showing electrical conductivity (2022)

Water-processed nanocomposites based on cellulose nanofibrils (CNF and 2D platelets are sustainable alternatives to nanocomposites from fossil-based polymers. The degree of dispersion of 2D platelets in CNF matrix is critical to mechanical properties, but reduced graphene oxide (RGO) has poor hydrocolloidal stability. This is addressed by forming electrically conductive and strong CNF-RGO nanocomposites by green chemical reduction of wet, vacuum-filtered CNF-GO cakes, taking advantage of the colloidal dispersibility of GO platelets in CNF, as characterized in the solid nanocomposite by SAXS, WAXS and FE-SEM. CNF-RGO nanocomposite with 2 wt% RGO shows a Younǵs modulus of 20.4 GPa and tensile strength of 319 MPa, with considerable ductility at 50 % RH. Although CNF-GO shows much higher moisture sorption than CNF-RGO at 90 %RH, the CNF-GO mechanical properties are higher, for thermodynamic reasons, MD simulations predict dry, hydrogen-bonded CNF-GO interfaces even in wet conditions, and this can explain the better performance of CNF-GO.
U-Groove Assisted Passive Assembly of 30x Single-Mode Fiber Array to Edge Couplers for Silicon Photonics (2021)

Scission of the epoxy ring in 4,5α‐epoxymorphinans: A convenient synthesis of β‐dihydrothebaine, 6‐demethoxy‐β‐dihydrothebaine and desoxycodeine‐A (Chemistry of opium alkaloids, Part XXI) (1986)

Abstract The use of zinc and aqueous potassium hydroxide for the reductive epoxy ring opening of thebaine ( 1 ) and 6‐demethoxythebaine ( 2 ) is described. The reaction affords exclusively β‐dihydrothebaine ( 3 ) and 6‐demethoxy‐β‐dihydrothebaine ( 4 ), respectively. The synthesis of desoxycodeine‐A ( 9 ) has been improved and evidence for its configuration is discussed.
Deliberate Clipping and Iterative Distortion Recovery for UCA-Based OAM Multiplexing Systems (2021)

Deliberate amplitude clipping is a simple and well-known technique to reduce the peak-to-average power ratio of orthogonal frequency division multiplexing (OFDM) systems. In this paper, we propose a clipping technique for peak power reduction in orbital angular momentum (OAM) multiplexing systems with uniform circular array (UCA) antennas. In the proposed technique, clipping is performed on digital baseband signals prior to OAM beamforming and pulse-shaping filtering, which helps to avoid out-of-band radiation and affecting the orthogonality of the OAM modes. In addition, an iterative distortion recovery algorithm is proposed in order to mitigate performance degradation in bit error rate (BER) due to the clipping. The algorithm is derived by unfolding the clipping noise cancellation (CNC) algorithm for OFDM systems into layers and by introducing layer-wise learnable parameters. Simulation results show that for a realistic OAM multiplexing system with 256QAM signaling, the unfolded CNC exhibits excellent BER performance even when the conventional CNC suffers from a high error-floor. The combination of the proposed clipping and distortion recovery schemes provides a significant reduction in the peak power of the OAM signals at the cost of only a slight degradation in BER performance.

Context-Based Web Service Clustering (2009)

Under web service environment, services' calling or called relationships are usually represented as links. Based on link- or link-content analysis, it may produce tight clusters, which is useful for resource management. However current work only considers the existence of collaboration and it seldom takes service usage context into consideration. In this paper, we suppose to cluster similar services by introducing service usage context which is the complete stories for services' activities and helps to improve clustering performance. Being different with link- or link-content-based clustering methods that considering one-linkdistance-away-neighbors (part of the activity story), this work proves that in team-up work situation, all collaborators (long-distance-neighbor) can provide information for distinguishing services.
SqueezeSegV3: Spatially-Adaptive Convolution for Efficient Point-Cloud Segmentation (2020)

LiDAR point-cloud segmentation is an important problem for many applications. For large-scale point cloud segmentation, the \textit{de facto} method is to project a 3D point cloud to get a 2D LiDAR image and use convolutions to process it. Despite the similarity between regular RGB and LiDAR images, we discover that the feature distribution of LiDAR images changes drastically at different image locations. Using standard convolutions to process such LiDAR images is problematic, as convolution filters pick up local features that are only active in specific regions in the image. As a result, the capacity of the network is under-utilized and the segmentation performance decreases. To fix this, we propose Spatially-Adaptive Convolution (SAC) to adopt different filters for different locations according to the input image. SAC can be computed efficiently since it can be implemented as a series of element-wise multiplications, im2col, and standard convolution. It is a general framework such that several previous methods can be seen as special cases of SAC. Using SAC, we build SqueezeSegV3 for LiDAR point-cloud segmentation and outperform all previous published methods by at least 3.7% mIoU on the SemanticKITTI benchmark with comparable inference speed.
Perceptual Organization in User-Generated Graph Layouts (2008)

Many graph layout algorithms optimize visual characteristics to achieve useful representations. Implicitly, their goal is to create visual representations that are more intuitive to human observers. In this paper, we asked users to explicitly manipulate nodes in a network diagram to create layouts that they felt best captured the relationships in the data. This allowed us to measure organizational behavior directly, allowing us to evaluate the perceptual importance of particular visual features, such as edge crossings and edge-lengths uniformity. We also manipulated the interior structure of the node relationships by designing data sets that contained clusters, that is, sets of nodes that are strongly interconnected. By varying the degree to which these clusters were "masked" by extraneous edges we were able to measure observers' sensitivity to the existence of clusters and how they revealed them in the network diagram. Based on these measurements we found that observers are able to recover cluster structure, that the distance between clusters is inversely related to the strength of the clustering, and that users exhibit the tendency to use edges to visually delineate perceptual groups. These results demonstrate the role of perceptual organization in representing graph data and provide concrete recommendations for graph layout algorithms.
Strength of Interference Screw Fixation to Cuboid vs Pulvertaft Weave to Peroneus Brevis for Tibialis Posterior Tendon Transfer for Foot Drop (2018)

The results indicate that early active dorsiflexion and protected weightbearing may be safe for clinical evaluation, with potential benefits for the patient compared with cast immobilization.
Voxel shapes in two-photon microfabrication (2003)

Maximization of scan speed and throughput while maintaining resolution is critical for commercialization of two-photon microfabrication technology. We report contrast curves for cationic and free radical two-photon polymerization. An unusual relationship between voxel shape and dose is observed where the voxel ranges from highly asymmetric (aspect ratio of 4:1 or greater) at high dose to nearly spherical low dose (aspect ratio 1:1 or lower). Similar behavior is observed for both types of polymerization systems suggesting that the change is aspect ratio is not a function of the specific type of chemistry. It is found that a simple optical model describing the intensity distribution near the focal point can predict the change in aspect ratio.
Pepsin immobilized on inorganic supports for the continuous coagulation of skim milk (1977)

The milk-clotting enzyme pepsin was immobilized onto beads of alumina, titania, glass, stainless steel, iron oxide, and Teflon for treating skim milk in a fluidized-bed reactor. Two covalent attachment procedures using silanized supports and glutaraldehyde and two adsorption procedures were evaluated. The three best catalysts were titania and glass, using the covalent attachment procedure, and alumina, using the adsorption procedure at pH 1.2. The pepsin adsorbed on alumina catalyst has commercial potential compared to the previously used glass catalyst. Attempts to increase the stability of pepsin adsorbed on alumina by cross-linking with glutaraldehyde were unsuccessful owing to the low pH necessary for optimum pepsin adsorption; Desorption of pepsin from alumina during reactor operation was determined. Regeneration of spent catalysts was only partially successful.
A Fuzzy Hybrid Sequential Design Strategy for Global Surrogate Modeling of High-Dimensional Computer Experiments (2015)

Complex real-world systems can accurately be modeled by simulations. Evaluating high-fidelity simulators can take several days, making them impractical for use in optimization, design space exploration, and analysis. Often, these simulators are approximated by relatively simple math known as a surrogate model. The data points to construct this model are simulator evaluations meaning the choice of these points is crucial: each additional data point can be very expensive in terms of computing time. Sequential design strategies offer a huge advantage over one-shot experimental design because information gathered from previous data points can be used in the process of determining new data points. Previously, LOLA-Voronoi was presented as a hybrid sequential design method which balances exploration and exploitation: the former involves selecting data points in unexplored regions of the design space, while the latter suggests adding data points in interesting regions which were previously discovered. Although this approach is very successful in terms of the required number of data points to build an accurate surrogate model, it is computationally intensive. This paper presents a new approach to the exploitation component of the algorithm based on fuzzy logic. The new approach has the same desirable properties as the old method but is less complex, especially when applied to high-dimensional problems. Experiments on several test problems show the new approach is a lot faster, without losing robustness or requiring additional samples to obtain similar model accuracy.
Immunomodulatory effects of functionalised chalcones on pro-inflammatory cytokine release from lung epithelial cells (2009)

Chalcones, prepared in high yield in polyethylene glycol, Mw = 300 (PEG300), were screened for inhibition of the thrombin-mediated release of pro-inflammatory interleukin-6 (IL-6) and interleukin-8 (IL-8) from the A549 lung epithelial cell line. Several show significant down-regulation of these pro-inflammatory mediators in a dose-dependant manner with one exhibiting pro-inflammatory properties. Computational studies on selected chalcones revealed a detailed understanding of the structure, electron density and biological activity relationship.
Generalized binary splits: A versatile partitioning scheme for block-based hybrid video coding (2019)

Block partitioning is the basis of every modern hybrid video coding standard. It specifies how the video pictures can be subdivided into blocks for prediction and residual coding. In H.265/HEVC, quad-tree partitioning is one of the key technologies allowing for flexible mode allocation and providing a substantial part of the gains over H.264/AVC. The current draft of the upcoming standard Versatile Video Coding (VVC) provides over 30% bit-rate savings over HEVC and almost one third of the gain is achieved by using a more flexible partitioning scheme than the quad-tree partitioning used in HEVC. In this paper, we describe a partitioning concept that generalizes many of the ideas developed during the exploration and early standardization phase of VVC. In fact, our method includes the VVC partitioning as well as many other state-of-the-art methods. The proposed method can be implemented in a fully configurable design. For instance, it can be configured to match the performance of VTM-1.0 at much faster runtime (69%) or it can be configured to obtain additional bit-rate savings of up to 3% by exploiting additional degrees of freedom.
