Owing to rapid progress in field of nanotechnology, various mathematical model has been proposed regarding the flow of nanofluids. Based on boosted thermal properties, multidisciplinary applications of such materials has been claimed in various engineering and industrial processes. In current work, a theoretical analysis is performed for bioconvective flow of Carreau fluid with applications of magnetic dipole. The significance of magnetic dipole are presented with interaction of ferrofluid. The applications of viscous dissipation have also been entertained. The flow is subject to applications of stretched surface. Similarity variables are used for making transformation to obtain set of nonlinear ODEs from set of PDEs. The numerical computation is also made by using of well-known numerical method termed as bvp4c. Influences of various non dimensional fluid parameters like Brownian motion, viscous dissipation, Curie temperature, Weissenberg number, motile difference parameter and bioconvection Paclet number are examined and expressed graphically. It is perceived that ferrofluid's concentration declines when Brownian diffusive variable is augmented while opposite characteristics are reported for Schmidt number. Current results conveying applications in the biofuels, better heat transport medium, fertilizers, catalysts, electronics, paints, semiconductors, speakers, drug delivery, fertilizers etc. © 2024 The Author(s)

Large-scale pretrained language models are the major driving force behind recent improvements in performance on the Winograd Schema Challenge, a widely employed test of commonsense reasoning ability. We show, however, with a new diagnostic dataset, that these models are sensitive to linguistic perturbations of the Winograd examples that minimally affect human understanding. Our results highlight interesting differences between humans and language models: language models are more sensitive to number or gender alternations and synonym replacements than humans, and humans are more stable and consistent in their predictions, maintain a much higher absolute performance, and perform better on non-associative instances than associative ones. Overall, humans are correct more often than out-of-the-box models, and the models are sometimes right for the wrong reasons. Finally, we show that fine-tuning on a large, task-specific dataset can offer a solution to these issues. Copyright © 2020, The Authors. All rights reserved.

We use quantum mechanics (QM) to determine the states formed by B dopants in diamond. We find that isolated B sites prefer to form BB dimers and that the dimers pair up to form tetramers (BBCBB) that prefer to aggregate parallel to the (111) surface in the direction, one double layer below the H-terminated surface double layer. These tetramers lead to metallic character (Mott metal Insulator Transition) with holes in the valence band near the Γ point and electrons in the BBCBB tetramer promoted band along the X direction. Our experiments find very significant anisotropy in the superconductivity for boron-doped diamond thin films prepared with Microwave Plasma Assisted Chemical Vapor Deposition using deuterium-rich plasma. This leads to much higher conductivity in the X direction than the Y direction, as predicted by the QM. This phase transition to the anomalous phase is linked with the emergence of boson quantum entanglement states behaving as a bosonic insulating state. These anisotropic superconducting properties of the diamond film might enable applications such as single-photon detectors. We expect that this formation of a dirty superconductivity state is related to the BBCBB tetramers found in our QM calculations. © 2024, The Authors. All rights reserved.

There are considerable obstacles against realizing practical quantum computing: a significant amount of computation errors and the restricted qubit count. As a unified method of noise-agnostic quantum error mitigation (QEM) methods, i.e., the quantum subspace expansion and virtual purification, a generalized quantum subspace expansion (GSE) has recently been proposed that is significantly robust against stochastic and coherent errors. However, GSE requires entangled measurements between copies of the quantum states, which is a significant drawback under the current situation of the restricted number of qubits and their connectivity. In this work, we propose a resource-efficient implementation of GSE, which we name "Dual-GSE", circumventing significant overheads of state copies by constructing an ansatz of error-mitigated quantum states via dual-state purification. Remarkably, Dual-GSE can further simulate larger quantum systems beyond the size of available quantum hardware with a suitable ansatz construction inspired by divide-and-conquer methods that forge entanglement classically. This also significantly reduces the measurement overhead because we only need to measure subsystems’ Pauli operators. The proposed method is demonstrated by a numerical simulation of the eight-qubit transverse-field Ising model, showing that our method estimates the ground state energy with high precision under gate noise with low mitigation overhead and practical sampling cost.

The cybernetic essence of the data extraction process at the level of end nodes (intermediate links of the information exchange path) is considered in the article. Authors consider and generalize the context-oriented problem of control action transferring to a specific activation point (transfer perceptron (response node)).The authors consider the subject area - distributed response networks. The role of addictive technologies in the process of formation of a complex control action or command and their transmitting is indicated. A simulation balance model is being developed for a routing model in the spatial field of an industrial computer network. It implements the method of filtering and disaggregation of automated technological process control lines according to a group criterion (by the method of sets determination).The introduction of hardware control of the model of the authentication system of automated line devices using the method of data multiplexing and the apparatus of fuzzy mathematics is given, formalized and considered, taking into account the use of a cryptographic flow limiter (unidirectional hash function, which has an integrated address controlled impact).Authors generalize a probabilistic model for calculation of the efficiency and expediency of the functioning of this system for a four-loop motion control line. Calculation of the standard deviation and variance for the emulating output of the considered perceptron is given. In conclusion, a block diagram of the developed device is presented.

In many practical applications, deep neural networks have been typically deployed to operate as a black box predictors. Despite high amount of work on interpretability and high demand on reliability of these systems, they typically still have to include a human actor in the loop, to validate the decisions and handle unpredictable failures and unexpected corner cases. This is true in particular for failure-critical application domains, such as medical diagnosis. We present a novel approach to explain and support an interpretation of a decision-making process to a human expert operating a deep learning system based on Convolutional Neural Network (CNN). By modeling activation statistics on selected layers of a trained CNN via Gaussian Mixture Models (GMM), we develop a novel perceptual code in binary vector space that describes how input sample is processed by the CNN. By measuring distances between pairs of samples in this perceptual encoding space, for any new input sample, we can now retrieve a set of most perceptually similar and dissimilar samples from an existing atlas of labeled samples, to support and clarify the decision made by the CNN model. Possible uses of this approach include for example computer-Aided Diagnosis (CAD) systems working with medical imaging data, such as Magnetic Resonance Imaging (MRI) or Computed Tomography (CT) scans. We demonstrate the viability of our method in the domain of medical imaging for patient condition diagnosis, as proposed decision explanation method via similar ground truth domain examples (e.g. from existing diagnosis archives) will be interpretable by the operating medical personnel. Our results indicate that our method is capable of detecting distinct prediction strategies which enables to identify most similar predictions from an Copyright © 2020, The Authors.

Waste application, beneficial in terms of soil abundance in nutrients, cannot lead to soil contamination. The incubation experiment aimed at assessing the effect of applying sulfur pulp (waste material containing elemental sulfur) and ground phosphate rock on the availability of heavy metals in soils. The experiment was conducted on two soils with different soil category: Medium and heavy, both of acid reaction and not contaminated with heavy metals. Doses of sulfur pulp and phosphate rock were set based on soil abundance in sulfur and phosphorus, guidelines on the limit content of these elements in soils, and on the principles of crop fertilization. Doses of 20 and 40 mg S as well as 40 and 80 mg P · kg-1 DM were added to medium soil;30 and 60 mg S as well as 60 and 120 mg P · kg-1 DM were added to heavy soil. The experiment comprised: Control soils (without additions), soils with only sulfur addition (in both doses), soils with simultaneous sulfur and phosphorus addition (in both doses). The content of available forms of heavy metals (Zn, Mn, Ni, Cd, Pb) in the soils was determined after 90 days of incubation. The elements were extracted with: 1) a mixture of 0.1 mol ∙ dm-3 hydroxylammonium chloride and 1 mol ∙ dm-3 ammonium acetate;2) 0.01 mol ∙ dm-3 calcium chloride. The element content in the solutions was determined by inductively coupled plasma optical emission spectroscopy (ICP-OES). A higher content of trace elements was recorded after extraction with a mixture of hydroxylammonium chloride and ammonium acetate than after extraction with calcium chloride. Trace content of Cd and Pb was extracted with calcium chloride from both soils. Moreover, trace content of Ni was extracted from the medium soil with both reagents and trace content of Cd was extracted from the heavy soil with the mixture of hydroxylammonium chloride and ammonium acetate. Introduction of sulfur pulp and phosphate increased the content of manganese extracted with calcium chloride (especially
